    A quality product. I carry it in an old sock to save it getting scratched in my laptop bag. It recharges my Lenovo laptop in a couple of hours over USB C. One point to bare in mind, when charging a laptop, the laptop thinks it’s connected to mains power, so remember to adjust your laptop power settings if you are seeking maximum run-time from this power bank whilst also using your laptop at the same time.

    I bought this for a long flight, but didn’t use it on flight. However when I tested it out, it provided 4.5hrs extra for my Windows laptop. So it literally doubled the battery life for my laptop. Extremely pleased with it. It is on the costlier side, but it is true PD100 (well my laptop charger is 65W so it is able to pump out that much atleast…)

    If you charge using a phone charger it will take forever to charge, that’s not really the battery banks’ problem. With my laptop charger (65W) it charges in a few hours.

    Phones/tablets it will charge multiple times, I wasn’t keeping track.

    Some people are complaining it isn’t charging. I noticed this too. This happens if your Earth line is open or other wiring weridities like neutral-live swapped etc. Try changing the plug point you have plugged it into. I had a dodgy plug point in my room where it just won’t charge.

    Power in einer Hand. Die Leistung ist sehr gut. Allerdings ist die Powerbank relativ gro und nicht sehr leicht. Aber das war mir vorher schon klar und fr mich zhlte die Leistung, welche mich auch berzeugt.

    Ich habe mir diese Powerbank gekauft, weil ich mit ihr die Aufnahmedauer meiner EOS R5 C verlngern wollte. Deswegen brauche ich auch die PD-Funktion, die einwandfrei funktioniert. Die Powerbank ist von den Auenmaen scheinbar nicht wesentlich grer als die in ihr verbauten Akkuzellen. Diese befinden sich in einem schlichten, schwarzen, an den beiden Seiten abgerundeten Gehuse mit 4 kleinen LEDs, der Powertaste zum Prfen des Ladezustands und eben den drei USB-Anschlssen (2x USB C, 1x USB A).
    Habe mit ihr erst einen Drehtag hinter mir, bei dem sie souvern die ntige Leistung zur Verfgung stellte und am Ende noch mehr Restladung hatte, als ich gedacht htte. Es ist sicher kein Leichtgewicht, aber wenn ich sie bei Aufnahmen im Kamerarucksack lasse, ist das kein Problem. Ich finde sie prima!

    I’m not saying it’s heavier than it says on the tin, but don’t buy this to stick in your pocket for a boost. This one is for a weekend away camping or something

    High capacity power bank with up to 100W on a PD charging port is capable to charge with no problems for most USB-C laptops including MacBook Pro. My Dell XPS 9650 is happy with the extra juice when I’m somewhere off the grid.
    It’s pretty big size-wise but it needs to be to provide such impressive charging power.
    It’s probably one of the best power banks in this price range in my opinion.

    True Powerhorese among the powerbanks

    I purchased this item to be a backup charger for my Microsoft Surface pro 8. And it charges it very well, to about 85 to 90 per cent. I’m a power user so can’t complain. The included c to c lead is great at 95 cm. The a to c lead is a meagre 45cm. For the price it would have been nice to include a wall charger. Overall very satisfied though.

    Powerful and well built power bank, I’ve used it to charge my laptop while on the go, it holds enough charge to charge 11 mobile phones so can last week’s on a single charge if your traveling.

    For those with more modern laptops and devices, having a power bank is one of the most useful things to own, especially when travelling.

    This power bank claims to have a capacity of 26,800mAh and an output of 100W. While it’s got a high capacity, I’m not exactly sure if this reaches its maximum claimed capacity as my Dell laptop battery has a capacity of ~7500mAh, but this power bank only manages to give it a full charge twice when it should be doing it at least 3 times..

    There are 4 LED’s that indicate the remaining capacity. Each LED will represent ~6700mAh so it serves as a good indicator of how long it’ll last and when it requires a recharge.

    There are 3 ports on this power bank – two USB-C ports that can be used as output (one of which can be used as an input to charge the power bank) and a single USB-A port. These ports all support Quick Charging with a compatible cable.

    Charging speed when using this is dependent on whether the laptop was still in use and what was being done.
    On an idle screen, the charging speed was fairly quick and met my expectations.
    When I was watching a video or doing some work, it did take longer understandably, but was still quite quick.

    For travel, it would be quite useful if you do not have an opportunity to use a wall charger. However, bear in mind that it is quite bulky and thick – this is not like the power banks for phones.

    Charging this power bank does take a while but this also depends on the type of cable / wall charger used. As long as the cable/wall charger support a high output (65w+), this does completely charge up to full in a few hours.

    At 89.99, I do think it is quite overpriced as the only thing that sets it apart from others with a similar capacity is the fact that this can handle an output of 100W.

    Overall, a solid high capacity power bank that does a good job in charging up USB-C laptops and other devices.

    This power bank is heavy duty, it charges up iPads and iPhones so much faster than any other one I’ve tried, and the capacity is huge.

    The device itself is quite hefty as you’d expect, but not too big or heavy that you wouldn’t want to carry it around in a backpack.

    It’s a sleek unit and seems really well made.

    I badly needed this type of power bank. Recently for teaching purposes, I have travelled to some rural areas in some developing countries where there was a power cut and I struggle a lot with my teaching work.

    The capacity of this power bank is good that’s why it is heavy as well. I am using it to charge my Macbook and so far it is doing a good job. For the last one month, I am using it for at least one charge and I have been not disappointed. This is really a great solution and back for my battery.

    I am glad I got this for review purposes and after one month of use I am giving it five stars and it also comes with two years warranty. I think it is a good product and very useful for backup power for laptops.

    I ordered this power bank for my MacBook.

    Arrived in small branded box with USB – C and USB – A leads.

    Very robust power bank, it is thicker than my MacBook but still looks sleek in aluminum casing.

    Has ability to charge 3 technology items at once, this is the first power bank that I have had that is capable to actually charge not just power my MacBook.

    4 LED indicators tell you the amount of charge on the power bank, on / off button ensures charge stays on bank when not used.

    Perfect solution to prevent any power emergency or just to be used if you are not able to be sitting near a mains power supply.

    Overall, excellent quality powerful and long lasting power bank, actually works for MacBook

    I would recommend this product.

    Amazing quality, seems robust, works finely with no issues, Very reliable, easy to use. Charges devices quickly, plenty of power. It Charged my phone twice while on a camping trip and still had power left.

    The portable charger has a few ports so you could charge multiple phones or iPads at the same time. By the way the Charging cable could be a bit longer.

    Only gripe is it’s rather heavy , a lot heavier than I expected, that’s the only reason I have not given it 5 stars , and takes quite a while to fully charge . It is very bulky and not something you want to carry around with you, but on the other hand it needs to be this way for that huge capacity.

    I got this laptop power bank as my backup power source whenever I am travelling and there’s no socket or power source available in the area.

    The power bank has a 100W PD port that supports most USB-C powered laptops. It has 2 USB-C ports which you can use to simultaneously charge two different devices without compromising the charging time. It can charge a MacBook Pro 13 from 0-45% in 30 minutes or an iPhone 12 from 0-60% in 30 minutes. It has a 26800 mAh battery capacity that can extend your gadgets battery life when needed. It can also be fully charged in only 2 hours and 30 minutes by using a 65W PD wall charger.

    In addition, once you purchase this you will be getting a PD 100W Power Bank, USB C-C Cable, USB A-C Cable and user manual. You will be also getting a 90 money-back guarantee and replacement if something goes wrong.

    Well, I didn’t expect this laptop power bank to be this good! It is indeed heavy-duty and charges my laptop well. Its build feels so solid even though it is big, however, that is acceptable since it has a large battery capacity and is super powerful. I tried charging my phone with this power bank and it charges faster than my usual mobile power bank. I think this one is also a great power backup at home in case of emergency.

    In all honesty, this product is a good investment for personal use, travel or even emergencies. It is not pocket friendly but still definitely worth it.

    This definitely is a very capable power bank, it’s designed for laptops and power hungry devices rather than phones and tablets, and it definitely delivers what it promises.

    The unit is compact in size, but it does weigh a fair bit, it won’t be my choice if I was planning on moving/carrying it, but it’s definitely my choice while stationary.

    Included cables are limited to 60W charging, but having tested it with PD cables it did deliver around 96W, which is really impressive for a sub 100 unit.

    Overall: At 79.99 at the time of reviewing, this is an excellent power source for anyone with power hungry devices on the go, it will definitely deliver. Would definitely recommend.

    : Top Tip : It has so many levels of protection, that it is a very safe and safety orientated product.

    : Top Tip : It will recharge most phones 5 or 6 times before needing recharged itself. Very impressive.

    : At 79.99, at the time of writing,

    This :

    : 2 USB-C Ports Laptop Power Bank, PD 100W 26800mAh Quick Charge Portable Laptop Charger, Fast Charging External Battery Pack for MacBook, iPhone, Samsung, HP, Dell, Lenovo and More

    Looks to be a great, and very handy, bit of kit, that could save your bacon…

    But…
    Is it any good?
    Is it good value?
    Will I get a lovely cup of tea , at any point during this review?
    And possibly even a biscuit ?
    Well… the answers to these, plus perhaps, one or two, extra, questions, we might accidentally stumble across, during the course of my meandering, and often erratic, review, we should take a closer look… …

    Packaging :
    It arrives in a lovely, shiny, professional, retail ready box.
    The level of packaging is not excessive, or profligate, and is just enough to keep the product safe, and out of the box in good condition.
    It makes a very good first impression.

    Recycling :
    All of the packaging can be recycled, including all of the inner contents.

    Contents :
    Out of the box, and the contents are easily catalogued:
    1 x PD 100W Power Bank,
    1 x USB C-C Cable,
    1 x USB A-C Cable,
    1 x User Manual
    Very nice.
    Everything required to get up and running, straight out of the box.

    Build Quality :
    It has no ragged edges, no mould marks, or dodgy junctions.
    The level of finish applied to the product is excellent.
    It’s all beautifully finished, and looks the business.

    I can’t put it any better than the manufacturer, who rather poetically described the power bank as follows:
    “This power bank is rather swish — it’s made of anodized aircraft-grade alumin[i]um-providing flame retardant and falling prevention. The frosted texture and slickly rounded edges offer a superb touch and stylish appearance.”
    Quite.

    Features :
    The power bank measures : 177.5 x 79.5 x 22 mm
    It weighs : 500g

    It has a huge capacity of : 26800mAh
    Enough to charge most mobile phones five. or six, times over from flat, to fully charged.
    That is a serious amount of power, from a relatively small power bank.
    It is very powerful too, recharging at 100W via USB-C (PD).

    It can charge three devices simultaneously.

    It utilises a Quick Charge 3.0 USB-A port, giving a super quick charging option.

    It has two USB-C ports plus one USB-A port, giving three fast outputs that can be utilised altogther.

    Pass-through charging is available.

    Safety wise, the powerbank has enough safety features to keep every one happy, safe, and not on fire.
    It has the following protections :
    circuit protection,
    overcharge protection,
    over discharge protection,
    overvoltage protection,
    over temperature protection,
    current limiting protection and
    over-current protection
    Very nice.
    That should keep my laptop, and phones the way I like them…. Not on fire .

    Set Up :
    Set up is genuinely easy.
    You simply plug it into the phone or laptop needing charged, and the smart powerbank will do the rest.
    It will detect the amount of power required, and what speed it is to transfer at, and it will safely charge until the item needing charged is full.

    Performance :
    In testing, the power bank performed flawlessly.
    It charged and charged, until it required charging.
    Which didn’t take too long, just two and a half hours, and then it was back charging again.
    It was not outfoxed by any rogue items we tried to plug in, refusing to charge any unsuitable items.
    The ones that needed charging were charged quickly, and without any fuss.
    It was very impressive, and was seriously professional in its speed and power.

    Downsides :
    No downsides were noted during testing.

    Value :
    At around eighty pounds, this feels like a bit of a bargain.
    It is terrific quality, and you are not paying a ludicrous amount, so it looks to be a great price.
    I would happily pay the asking price.

    Summary :
    Overall, this powerbank is brilliant.
    It is so well-made, so well-designed, and it performed perfectly in testing.
    It has a nice large capacity, and charges very quickly.
    It has everything you could ask for a compact powerbank.

    Recommendation :
    I do not hesitate to recommend it highly.
    It is a very good product.
    Now… about that cup of tea? Ooh, lovely.
    Biscuit ?

    I hope you enjoyed our time together .
    Thank you for reading my review .

    This is beast power bank amongst all power banks on the market. When comes to capacity it is nothing extraordinary, fits rather on top league but this power bank have advantage on power and charging possibilities. It does deliver massive 100W to charge big laptops such a Macbook pro, thinkpad and others laptops which suport usb-C and PD as well all tablets.

    When connected to device it detects output needed and possible and deliver just right to safely charge in fastest possible way. This is truly intelligent and powerful power bank. Very heavy in hand, on front you have access to 2x USB-C port as well 1x USB-A, power button as well 4 diodes indicating charge level of power bank. I love that producent supply power bank with 2 extra cables, usb-c and usb-a cable, great touch.

    It is just perfect power bank for my ipad Pro, extremely fast charging and also huge plus, you can charge up to 3 devices simultaneously so ipad pro and iphone without any problem. Very pleased with this power bank.

    Powerful on delivering massive charge 100W

    This is one of the best power banks I had so far with the largest capacity also.
    After having to return 2 chargers which were advertised as being compatible with my MacBook but they weren’t I decided to get a large power bank instead as it gives me more freedom while working away so I don’t have to rely on sockets.
    It charges my MacBook to full and there is still power left to charge my phone if needed. It’s my first power bank of such a large capacity and I’ve honestly expected this to be chunkier but it’s not so much bigger than my 10000mAh power banks, it’s quite compact actually and easy to carry. Very happy with it so far.

    This is a huge capacity powerbank that just seems to go on and on charging my Samsung Galaxy S20 Ultra. In reality it probably is five or six times.

    It delivers ‘Fast Charging’ to my phone. Its odd though as it starts off as ‘Ultra Fast Charging’ for a few seconds then reverts to just Fast Charging. Still Fast charging is good enough for me.
    It seems very well made and looks sleek and smart and isn’t heavier than I’d expect.
    It doesn’t get hot during use.

    This power bank is heavy duty and bulky in terms of size and weight-it’s like a small brick.
    The power bank works well and it is possible to charge up to 3 devices at once,including a laptop.The power bank has aircraft grade, aluminium housing and has a nice,black finish.
    It’s a little too large and heavy for everyday usage but for usage at home or for an extended trip it is effective.
    The product is well overpriced and a little too bulky for my liking.
    My rating is 4 Stars.I hope you find my review helpful.

    Built well and comes in at a costly 80 (at the time of review) it is one of your high end power bank. That said it will power a laptop (check notes or ask the company to make sure your laptop is supported) this is great for me when on the go and when I just can’t get to a power source. I have also used it on my Nintendo Switch which as people know doesn’t last long on the battery itself so this was a nice power brick to have with me.

    The downside is that it’s pretty heavy, nice to have on a table when using a laptop or on a armrest when playing my switch but not something I could easily hold in my hand for long periods of time.

    The push of a button will tell you how much battery is left, it comes with two cables a USBc to USBc and USBc to USBa. On the front there are slots for USBa and two USBc (in and out). The brick charges up quickly too, I didn’t have to wait longer than three hours for a full charge.

    Ideal for working where there isn’t power available and car journeys where there isn’t a power slot.

    *Doesn’t come with a PD cable.

    Having already used a similar product I bought for my other half that cost an awful lot more than this, I wasn’t expecting too much from this handy little power bank but I was wrong.

    This powerbank is designed for a laptop, many of the others will not charge a laptop hence the cost of this however, I bought my other half the Omnicharge power bank when laptop power banks were a new thing almost 4 years ago; it’s still going strong by the way and is around 20000mah. It cost 230. The new ones I note, still cost around 200 so this little one at 70 is an absolute bargain.

    Omnicharge = 496g — the square one on the right
    Easylonger = 555g — on the left

    I’ve been using this to charge my XPS13 and it pretty much does it once from empty to full which is what I expected and is what the Omni does — just. This one has a little to spare at the end.

    In action the two are absolutely comparable, the only difference is this one only has 4 little LEDS to give you any idea of the charge. No percentage figures or little lights for this and that. It’s basic but it is a viable cheaper option and I will be using this a lot on my travels.

    Great value for money

    This is a top quality professional power bank. It is big and heavy is this item but that’s alright it isn’t a carry in bag power bank and isn’t marketed as such. It is a power bank for the traveling professional who needs power when off grid. This power bank quickly re charged my laptop and a torch at the same time. With a capacity of 26800mah there is lots of spare power here. Comes with 2 USB-C & 1 USB-A ports. Perfect that. This power bank recharges at 45W. Very very pleased.

    In the box you get usb c cable doubleheader, instructions and of course the battery. However why the PD cable was not included is a missed opportunity, would have given a edge in the market place here.

    However I really impressed with power of this. Yes it will charge anything usb c, having in and out connections great addition

    Powered my multi adapter, 2 hdmi screens, keyboard, mouse, iPhone plugged into the adapter, whilst charging my laptop and working at same time for 3 hours.

    Where my laptop on it on cannot drive all those connections at one on it’s on.

    In summary a sturdy power bank that does it job, just wished a main PD cable was also included..

    Almost perfec

    This is one seriously heavy power bank – and I am literally just referring to the weight of it here – it’s 573g and feels like a small dumbbell. It’s not something I’d want to lug around in a bag BUT it’s ideal for using around the home, during a long journey, for a coffee shop work session or an intensive study session – anywhere, anytime you’re going to need a fast charge up – and it IS definitely fast, reliable and heavy duty in the amount of power it can hold for you.

    I can’t really fault the quality of this product, I just didn’t notice how heavy it was so it’s not quite the carefree, take-everywhere-in-my-bag power bank I was hoping for. Alas, I’m a small human and of course, the weight may not bother you… It’s a high quality power bank, heavyweight, heavy duty with a hefty price tag to match.

    This power bank has a USB-C and USB-A output charging cables ( that is a two port type-c and a port type-c charging cables).

    It has a large capacity of 26800aAh, and can even change three devices as same time. It has wide compatibility, can charge mobile phone, tablets and laptops, and the charging speed is quite fast. Its weight is 500g and its length is 17.8cm. Obviously not fit for a pocket,it’s more suitable for luggage if you’re traveling.

    It doesn’t have a display, just a battery indicator. Personally I think the price is quite expensive even though it’s large capacity.

    My laptop is a bit worn out in the battery department and doesn’t last as long as it used to so this is a very handy power bank for me as I can get a full charge out of it with plenty to spare so going a whole day is now very easy, the power bank itself is very well built and has some weight to it, I guess because it has a lot of batteries inside, all in all, a life saver for me so gets 5 stars.

    This power bank is aimed at the professionals. It’s a not in your face design with no outrageous lights or anything and looks very sleek. 26800mah should be plenty to charge any laptop and it can be easily recharged when you are back at home or have a power outlet.

    Comes with 2 USB-C & 1 USB-A so can cater for all your needs. 100W Charging means it can charge the most demanding laptops (being the MacBook Pro’s) whilst also catering for the less demanding laptops such as a chrome book. It can also be used to charge phones and any other devices. It also recharges at 45W so it is relatively fast in that respect too!

    This is definitely a power bank you will not need to replace for a long time.

    This thing is HUGE. About as wide as an iPhone X and longer. So imagine the big iPhone X and it’s 1.5 times that size. Heavy? Yes again I would say it’s 3 times the weight. Does it work? Oh yes. Lots of power. It’s definitely not for popping in your pocket and probably needs a back pack to be honest. Otherwise I was impressed it comes with 2 charging cables.

    I like it, but its cost is too high. It is a bit bulky, and the large-capacity power supply can charge mobile phones and computers. If it is outdoor camping, then this large-capacity power supply is really a must-have.
    But its cost is too high. Two USB-C port designs and one USB port. It doesn’t have a number to show the power balance, but a blue light; there’s no light bulb that doubles as a flashlight.
    It only has one advantage that it has a large amount of power storage, but other than this advantage, I would consider other products at this price.

    I’ve tested a good few power banks and they vary wildly in their power and size. The two are inextricably linked. From the small light bank that is handbag/pocket friendly up to the big old reserve that can power devices over a long weekend. This is decidedly the latter. It is heavy.

    It’s a big black smooth unit with four indicator lights to give you some idea of charge level. It comes with a USB A cable and USBC cable. If you don’t already have one it is well worth investing in a USBC plug and/or USBC phone lead, but is much quicker.

    There are two USBC and one USBA outlets – which should cover most needs.

    The bank powers up pretty quickly on a usb C, only a couple of hours.

    Once full I’d estimate it could recharge my MacBook Air two times and phone/ipad half a dozen or more times. I’ve only tried recharging things once and am judging by how much the cell has depleted.

    Whilst not particularly pocket friendly it is ideal for a weekend “off grid”, if youre camping or travelling on transport without power points.
