    This is a great little charger. Compact and charges up with several types of leads and will charge your device no matter what lead you need. Charges up quickly.

    We bought a second one and I keep mine in my bag always.

    Would recommend.

    As stated above, this power bank gets to work as soon as it’s connected to a device. It’s lightweight and slim which makes it so much easier to carry around in say a handbag or jacket pocket. It’s got every port for all major devices and has a high output to charge fast which is wonderful for emergency reasons.

    5/5 stars for the price. Just note the size of this, it’s not something I would have in my pocket as a convenience but brilliant for camping or long journeys on the overnight ferry charging my laptop.

    This is an excellent portable charger – after hearing that not all battery packs on Amazon have the power they claim, it was a relief to test this and find that, from full, I could charge my phone (a Samsung S21 Ultra) four times. The pack feels well made and is a great size, just a little wider than a large phone, and comparable in length, depth, and weight. The number and variety of inputs/outputs is very good. I don’t think you’ll find better for the money and would highly recommend it.

    The charger is super easy to use. I have used it to charge my phone 5 times before having to charge it. There is an indicator that tells you how much charge is left. It is super sleek and skinny and easy to carry around. It comes with a carry case too.

    Golden Review Award: 4 From Our UsersGood, sturdy, pack -about the size of a large smartphone and a bit heavier, but slim enough to pack.easy. 5 input and 1 input/output socket (this includes a lightning and mirco USB).

    Mine came to me at 60% charge and took me 2 hours to get it to 100% on my Samsung branded charger.

    This power bank has a simple power level meter of 4 small LEDs – no digital display here

    One drawback are the 2 included usb cables. They’re very short at about 3-4 inches in length but more importantly, neither my Tab S7+ nor my A33 didn’t recognise them as fast charging, something to bear in mnd if you intend on using your device whilst charging. Use your regular branded cables.

    This product is more than impressive. Anker are usually my preferred device but I decided to give this on a go. It’s extremely powerful and not too heavy. I’ve charged many devices until it needed a charge itself. The power life is fantastic. Glad I bought it.

    The first thing I noticed with this was the weight of the unit. It was heavy for what it is! However, the charging output of the device is amazing and charges my phone extremely quick! It supports multiple inputs from different port types which is amazing!

    The only issue is it gets quite hot quite fast so I wouldn’t leave it plugged in for too long when charging. Apart from that, this is a great product and I never leave the house without it, especially because the iPhone battery is poor 🙂

    I can’t complain about how quickly this charges up my phone. Expect about 60% of charge within an hour. I took it abroad with me and managed to charge up at least 3 phones on a full charge. Would definitely recommend

    I’ll be as honest as I can be. I was very skeptical all the claims it does this and that. So I thought give it a try for the price it’s not a bank breaker. I can charge my iPad, charge my Grinder, phone, Chromebook. I’m super impressed am purchasing another to keep in car.

    1. Battery capacity is good for the size of powerbank.
    2. Sleek design, looks quite professional. Easy to carry in your jacket(if you don’t want to carry a bag)
    3. USB C inlet and outlet(same port)
    4. 4 parallel charges at a time(3 usb and 1 usb c)

    Golden Review Award: 3 From Our UsersI got it to charge my iPhone 14.
    First time is used it, it was charging slowly, like super slowly.
    I wanted to return it.
    After some Googling I found out that I was using the wrong charging port. Rather than charging through the USB connector port i began using the lighting USB type C port.
    Since then the phone has been charging within half an hour or less. I would definitely recommend it, lovely design, slightly heavy for obvious reasons and the colour is soo cute and girlie 10/10 I’m happy custome

    5.0 out of 5 stars WORKS REALLY WELL BUT…

    Golden Review Award: 11 From Our UsersFirstly I didn’t have high hopes for this powerbank at all. I wanted to buy an anker powerbank because I know they are the best brand but they’re just too expensive so I settled with this.

    Before this I had a 20,000mah baseus powerbank which used to charge my phone twice but after just a few weeks of use it broke and would only charge my phone once. That cost me 20 quid and baseus wasn’t helpful with returns so I was stuck with a heavy rubbish powerbank.

    I bought this and immediately loved the design. I like how you can charge with almost any cable be it usb c, lightning or even microusb. I like that it was thin and quite light but the weight made me suspect that it might have lied about it’s capacity (thankfully this wasn’t the case).

    Fully charged the powerbank up and drained my phone to 1%. Charged my phone up and over the course of 3 days I used this powerbank to charge my s23 ultra from 1% to 100%. It managed 3 full charges! This shows that the capacity of 26800mah is true.

    You need to remember that the 26800mah doesn’t mean you’ll get that much power out of it (even on an anker powerbank). You need to take into consideration the power factor and also that the phone charges at 5v, not at the 3.7v needed to achieve 26800mah. So after doing the calculations I was expecting between 3-4 full charges on my s23 ultra and the fact that it was correct proves that the capacity isn’t a lie.

    I also like that it comes with quick charging so I was able to fully charge my phone in just 1 hour and 20 minutes. If you use the slower USB A port to charge your phone then you’ll get more energy out of it because you the powerbank sacrifices some mah for speed when you use quick charge.

    Overall, fantastic product and I’m very happy with it. I hope it keeps it’s capacity unlike the baseus powerbank that I got before. If I don’t update this review it means that it’s still working perfectly. If it dies or gives me any issues I will update this review.

    Thank you charmast!

    5.0 out of 5 stars Charged my s23 ultra 3 times fully with a little more juice to spare

    I have several power banks, but this is the first one with a usb c outlet, it charges my iPhone promax really quickly to 80%, and not much slower to 100% and there is still plenty of charge left, ideal for a trip lasting a few days!

    Golden Review Award: 5 From Our UsersPurchased 2 of these for an imminent family trip to US. Used and charged about 10 times over the last 2 months…and they are brilliant…quick charge of phones and ipads…at least 5 charges before the need to re-charge unit. Comes with cables that suit both IPhone and Samsung charging lights plus 5 slots. What’s not to like. DWISOTT. 9/10.

    Golden Review Award: 6 From Our UsersI’ve had the Charmast power bank for nearly 3 months and so far it has been performing very well. I used it on a 5 day bike tour in my handlebar bag, and it easily kept my S21 Ultra plus topped up throughout each day of riding. This powerbank can charge my mobile 4 times and it does this very quickly. I also used it recently to charge up my Sony FX30 from 16% to 100% in a couple of hours. Having Charmast powerbank in my bag just gives me confidence and piece of mind knowing no matter how low my battery level is, I can just charge up while I’m out and about and on the move.
    The only thing I haven’t liked is the dirt marks on the white plastic body which I can’t get rid of, even with a screen cleaner spray, so I suggest you buy a black one.

    5.0 out of 5 stars Powerful and reliable. White prone to getting dirty..

    Golden Review Award: 129 From Our UsersOK, the first thing to say is that this power bank is VAST. Please read the dimensions before you buy it. I confess I didn’t and was amazed at how long and wide it is. It’s slim, but about 195mm long and about 95mm wide. It’s the exact size and shape of an 8″ tablet in fact, only thicker and heavier.

    For me, that makes it awkward. I would have prefered a more chunky shape but not so wide and long. Another power bank I bought, with slightly more capacity and a little bit heavier, was much easier to carry, but this one I can’t get my hand round it easily. I do not like the size and shape, although I didn’t read the dimensions, so that was my own fault and it loses no stars for that.

    But despite the awkward shape I’m probably going to keep it because it works very well indeed. I’ve measured the input and the output voltages and current levels and it performs pretty-much as advertised. Importantly, at maximum current output the voltage doesn’t drop much, and always stays above 5.0v Other power bricks I could mention suffer significant voltage drop at high current levels, and that will lead to slower charging. This one however manages tp keep the voltage up, and consequently keeps the Amps flowing at full speed.

    The other thing is that I wanted a power brick that supports pass-through charging. In fact I’m wanting to occasionally plug a tiny computer, like a Raspberry Pi, into its output, but also have the battery bank charging from the mains at the same time. I read that this one supports that function.

    Initially I thought that pass-through charging was not working, and in fact it wasn’t working to start with, but then I noticed that two of the ports had little lightning synbols next to them, and I wondered if those were for the pass-through power. Turns out they are, although the manual says nothing about that. With a mains charger plugged in via the USB-C port (which has that lightning synbol), and the load – the thing being charged – plugged into the one USB-A port with the lightning symbol, pass-through charging seems to work perfectly.

    However, if things are plugged in via either of the other two USB-A outlet ports then it all goes haywire: the output voltage drops badly and most of the current from the wall charger just gets sucked into the battery bank, leaving very little left for the phone or whatever plugged in. So I reckon if you’re going to use the pass-through power function you should not plug anything else in at the same time

    I checked this out using a USB power meter, so I could see the voltages at both inputs and outputs, and I am confident that the pass-through function works well. (I’m confident that the whole things worls well in fact. I hear what the manufucturers say in the answered questions here about how pass-through charging will work but it’s not really advised because it can shorten the battery life, but it does seem to work perfectly, and I’m happy with that. It’s not like I’ll be keeping it plugged in like that 24/7.

    So overall I think this battery bank works very well indeed. I just wish it were not so vastly long and wide. I would have been happier with the same weigth and volume but in a small brick-shape, something you can hold comfortably in one hand. But the thing works so well that I reckon I’ll live with the 8″ tablet shape.

    (Now if you actually had an 8″ tablet and you wanted to blutak this to the back of it to triple your battery life then that might work well!)
