Good,liked it,does what I want, better than my sandstrom,which takes forever to charge,fast charges android Motorola edge, using fast charge cable,also bike lights,and android tablet,with power to spare,will probably invest in another one.
great charger – easy to carry around – charge my watch and phone with ease.
Although this power bank works as described, it is pretty big and heavy. I wanted to use it while commuting (roughly 2 hours journey), but it didn’t seem practical as it can’t fit in my handbag and is heavy to carry around in my backpack along with my other essentials. So, I use it for short trips away from home (it is also ideal for camping) and it’s a great alternative if you are somewhere without easy access to sockets. I can charge more than two devices simultaneously and I found it to be very reliable, although as the number of devices charged at the same time increases, the charging speed decreases. The LED display is handy and gives you a clear indication of the remaining power.
As expected, it does take a while to re-charge once it’s finished, so I tend to leave it charging a night or two before my trip, ready for another journey.
It’s good quality, reliable, and I would be happy to recommend if you don’t mind the weight.
This is a massive 30000mAh Power bank. It is the same physical size as my iPhone XS, but three times as thick. It weighs 430g so this might need to be considered if you are taking this device when travelling.
This power bank has a USB C port, a micro USB port and two USB A ports.
It can be charged using the micro USB and the USB C ports. All the ports can be used to charge other devices.
It’s the receiving device that controls the amount of power drawn down. My phone charges from 20% to 80% in about about 40mins whilst my iPad mini was charging at the same time. The iPad was charging significantly slower as I was working on it and it was sharing the power with the iPhone. The iPad charged much quicker when it was charging alone, but about half the speed of when it is plugged in.
When charging my iPhone alone it can use a fast charging mode and a green icon is displayed next to the digital percentage display. This is very quick with my iPhone gaining 10% charge approximately every 5 mins.
The digital display shows the percentage of power in the power bank increasing when charging and decreasing when using it to charge devices.
This power bank comes with a USB A to USB C charging cable.
Overall this is a great device that seems a quality item and well made.
It is very useful when traveling, camping and when away from home.
This is a pretty good powerbank, it’s not the most powerful, but it’s also not physically too large to carry.
I tested it on my iPhone and iPad, it gave the iPhone a 50% charge and the iPad a 70% and 50% charge before it was used up. I realise the iPad Pro 12.9″ sucks a lot of power so the power output is fairly reasonable.
It has a handy digital display that shows you how much charge is remaining which is a good feature as often power banks with just status lights are often very hard to know how much power they have remaining.
It’s a solid unit and charges up my phone well, I like the digital display to show you the percentage of power left in it. I didn’t count how many charges I got out of it but it doesn’t last as long as another unit I have which is less power at 27500 hence the 4 stars instead of 5
If your out and about a lot then a power bank is essential so you can charge your devices on the go, the build quality is excellent this is a beast of a power bank and is the largest capacity I have had and it is the largest in size this will fill your whole pocket if carrying.
I took this to work with me so I could try it on a number of phones/watch on a single charge the devices was not that low on energy but did the job see the stats below
Iphone 14 pro max battery was at 66% this took 1 hour and 22 minutes to fully charge and the battery pack was at 88%
next Apple Watch series 8 battery was at 46% this took 1 hour and 7 minutes to fully charge and the battery pack was now at 86%
next Samsung A32 battery was at 43% this took 1 hour and 26 minutes to fully charge and the battery pack was now at 66%
next iPhone XS Max battery was at 34% this took 1 hour and 26 minutes to fully charge and the battery pack was now at 53%
Note I had to charge these devices one at a time as the people I got the devices from only had USB-C cables but the device has 2 USB-A ports, 1 USB-C port & 1 micro port overall I am happy with the power bank charged 4 devices and still at 53% remaining.
Ordered this for my son who loves weekends away camping , so having this battery pack allows him to have his phone charged no matter where he is. He has a Samsung galaxy s20 and this battery pack from full allows him 2 full charges and around half a charge on the 3rd attempt before the battery pack itself needs charged. So performance wise it is more than suitable for most weekends away. It also charges with a fair pace , taking around 80 minutes to fully charge his phone. The power bank is lightweight and slim and can easily fit in your pocket for carrying around. Price not available at the time of writing review so can’t comment on value for money but I’d be happy to pay around the 25 mark for this.
The device is quite chunky and weighs in at 430g and as quoted in the product specification does indeed weigh less than a 500ml bottle of water, which weighs 500g plus the weight of the bottle. It has rounded corners and a carbon-fibre like print on the top and bottom surfaces. All the ports clustered at one end, along with a power button. The connectors all work positively, and the various power cables that I tried it with all seated securely. The charging display give an indication of the power level, and you get a green LED and flashing numbers when charging. I did give this a lot of testing and my results were as follows.
USB-A ports are red and so are high power rated, and the product specification has these capable of discharge of 4.5A at 5v. In actual fact, they only achieve a maximum 3.47A at 4.1V. This is still good, but I really dislike a manufacturer that markets theoretical limits rather than what the product actually achieves. In any case, 3A at 5V is the max specification for this style of USB ports anyway. The capacity is also a bit disingenuous as 30,000mAh is only at 3.7V, and so when charging at 5V this capacity will be reduced.
The USB-C port is bidirectional and can be used to charge as well as draw power, and charging on USB-C can be 3A. The USB micro is for charging only and can be connected to a 2A power supply, but I had very poor results with this port, and it would not charge properly for more than a few seconds, although the power bank did recognize that there was a voltage present. The USB-C and USB mini ports are a little crowded together, I found.
Common adaptive voltage fast charging protocols QC2.0, QC3.0, AFC and FCP are supported on the USB-A ports only but not on the USB-C port. My Samsung settled in to charge at 9.1V quite happily. The power bank has impressive dual port charging capabilities as it would drive my test load at 3A and at the same time charge my Samsung phone.
The small charging cable is good from a power transmission point of view and is not just an afterthought with this product. I tested it with a 2A supply giving 5.40V at 10.80W and the cable only dropped this to 5.0V at 10.0W.
Despite these comments, I think it is a quite good power bank compared with some of its contemporaries, and with these devices, size does matter; the bigger it is, the larger the batteries are and the more power it has to give out. I particularly liked the multi-device charging capability. The positives out way the negatives, and the value for money is good, too.
For a portable power bank this is really quite chunky and heavy. But if you are going somewhere where there is no other way of charging then this is an efficient charger. It seems to hold its charge pretty well and you can put it on fast charge though I found it quite quick without doing this. It has two different charging sockets, one of them fitting an i-phone and a conventional USB slot. It works in much the same way as any other charger. The tiny print leaflet – typically Chinese – that comes with it warns you not to use it if it leaks or bulges which is somewhat alarming!! And the instructions are in completely incomprehensible English but the illustrations make it pretty obvious how it works. Not top of my list but it may well be just the ticket if you are going away to a non-technical place!
This is an essential item when you are travelling, as its perfect for charging my phone, it really makes a huge difference if you know you will not have access to power points. The item is small but quite heavy although not so as to put me off carrying it. Its easy to use, quick to charge from. I cant think of anything negative to say about it really. Recommend.
Brilliant size, capacity, power functions and finish, but the plastic has a slight chemically odour on first use. This disappears over time, so is likely just left over from manufacture. From then on, it’s a really impressive bit of kit though,.. Long lasting, powerful and dependable. Ideal for a weekend away for instance. Impressed!
Good quality power bank, really helpful when you are out and about and don’t have access to a power outlet to charge your phone. It is slightly on heavier compared to the ones I have had previously. It charges my phone quickly.
This is an excellent power bank. It has an indicator of charge left, which to me is the mark of a quality power bank, because the cheap ones never have that. It’s very easy to use, and charges rapidly: ten per cent charge in roughly ten minutes. It looks cool: solid black and weighty, so it feels it will last a lifetime.
Downside: it’s heavy, which i don’t mind, but practically speaking, you will need to be prepared to lug it around. The only real downside is the cost. I have tried two of these recently, both equally good, but the other was 25 pounds and this one was 32, so I’d be inclined to take the cheaper option. If you DO buy this,you won’t be disappointed..it is a quality item thar works very well. And if you can get one for less than 30 pounds, I’d jump at it. Great item, well worth having.
My 10,000mah power bank is 167g
This is three times the power and weighs 432g, that would equate to 144g per 10,000mah
This power bank is taller, wider and deeper, but not three times the size.
Measurements are 150mm high, 75mm wide and 27mm deep.
There is no bag to keep it in, all you get is the power bank and a very short subA to usbC cable.
On top of the unit you have two usbA ports, a usbC port ( PD) and a micro usb port, the later two will charge the power bank up.
On the side is the power button, to be fair plug it into something and power comes on anyway.
You know power is on because the display lights up with what percentage of battery is left.
If the unit is being charged the dis0lay flashes as power goes up.
This is a hefty unit, probably more than I would want to carry in a pocket.
It’s more suited to a bag or backpack but that is very much personal choice.
This power bank will happily charge a smartphone or iPad, it is holding a lot of power and will charge more than one device at a time.
Whilst I have been typing this on the iPad, the battery has remained constant and the power bank has gone down 1%
Good value
This power bank works well but it is heavy and bulky, not something you’d slip in your handbag for a night out. It’s currently priced at 29.99
The power bank has a large capacity and can charge an iPhone 8 times and most android phones 6 times before it needs to be charged again, it does charge pretty quickly too. There’s a battery indicator at the top of the power bank so you’ll always see at a glance how much power is remaining
The power bank has ports for both iPhone and android phones such as Samsung, Huawei etc. And it does charge pretty quickly which is good, just a pity its so heavy to carry around
The power bank comes with a USB C charging cable and a small instruction booklet, but it is really easy to use even without reading that
I think this power bank is ideal for camping trips or festivals when you won’t have access to a power socket, but not so on a night out as its quite heavy. It is a good power bank and I have been impressed with how quickly its charged my phone
