Power Bank,【26800 mAh High Capacity】Portable Charger Fast Charge with 3 Outputs & Type-C Input External Battery Pack with 4 LED Lights Ultra Compact for Smart Phone, Tablet - Classic Black

To take on ling weekends away.

I have a USB voltage/current measuring device, they only cost a few pounds/dollars, I can recommend them. With this I can give you a direct comparison of this battery pack vs my three-year-old RAV Power Ace Series 22000 mAh unit that I was hoping to replace.They are of similar size and weight, which I took as a good sign.When it came to powering other devices, I found that it would charge my 80% charged iPhone 8 at 0.7 amps, roughly the same as my RAV Power, but was struggling (the voltage dropped). For a more power hungry device, it maxed out at 0.8 amps where my RAV Power battery provided 1.2 amps. Note that I have never seen the 2.1 amps these things claim to run at, and it really does depend on the cables and what the devices in question are prepared to take. My main point is that my three-year-old RAV Power battery pack of the same size and weight out-performed this one which claims to have higher specs in every respect.The unit ships empty, so I gave it a full initial charge. I have USB charge meter that counts voltage and amps, and it told me it unit charged at 0.8 amps for 8 hours, which adds up to 6400mAh, but as I didn't do the same test with my RAV Power unit, I don't want to make any claim about this number because I believe either my measuring device is broken or (more likely) every single manufacturer inflates their figures. As I said above, I've never seen 2.1 amps reported, except in a case where there was literally smoke coming out of the device at the other end.My conclusion is that this unit is about what you pay for. It will likely keep your phone going for about a week, and will do you nicely for a weekend away. Compare it to ones that claim to be 22000 mAh, and my advice is simply to go by weight: If one battery claims to have 50% extra capacity but weighs the same as another, consider the manufacturer of the one with the lower claim to be the more honest manufacturer.

Bought this power pack to keep my devices charge on camping trips. Work well keeping both my and my wife's phone and watch charged for two whole days and nights. If the indicators are accurate we could have at a pinch possibly squeezed another day or two charge. As there were 4 devises to charge an extra usb port would have been handy. You need to allow time to charge the battery pack as it is as slow. This is by no way a criticism as by the laws of physics this is to be expected. Its a little weighty but overall a good bit of kit. Well pleased with the purchase.

This is exactly what I was looking for. With recent news that there may be blackouts in the UK over this Christmas period, I wanted something that I could use to charge my smartphone, so I still have access to my alarms and it's torch feature in case of an emergency. I also wanted something to charge my phone and ps4 controller when their battery levels were running low, so I could keep them close to hand.This turned out to be the perfect solution. I used the device to charge my phone and controller regularly until it ran out of battery to guage how good the battery life is and it only ran out the other day after about 9 days of continuous use.I of course won't use it like this in the future, which means using it only when I desperately need it, will hopefully increase battery life even further.Charging the device up again takes a bit of time but that is of course expected due to size of the battery within it. It is fairly heavy but again this is expected and doesn't really stop from keeping it close by, especially if you use a longer cable and place at on say a side table.The device charges at a good speed and works like a charm for what I needed.I haven't had reason to take it out of the home as of yet, but I believe it would work perfectly on the go if your battery in your mobile is running low.It uses led's to tell you how much battery remains, which I may have preferred a digital screen, but this works perfectly too and allows me to keep an eye on how much is battery is remaining and allows me to guage when to charge it next.Overall, the device works perfectly for what I wanted/needed and I can only imagine it will continue from here on out.

Good quality

I don't often write reviews any more, but I was nervous about purchasing a power bank as I was so close to my holiday when I thought of it, I didn't have time to return it if any concerns.. thought it might help someone in the same position, as there are so many on the marketplace! I HAVE NO REGRETS ON MY PURCHASE! (maybe that should have been the title?!)Only downside is the weight - quite heavy in your pocket - but given its capacity I'm happy to carry it (not bulky - about the same size as my S8, a little thicker).Owned 6 weeks now, still happy.

It worked for the first charge. After I charged the device once and the lights were showing fully charged, I tried to use to charge my iphone and the lights simply don't light up and it doesn't charge. I have tried other devices and it stopped working to charge all devices. It seems it doesn't recognise. When I plug in the socket to charge the device itself, it shows one steady light but it doesn't light up the other lights like when it is charging.I bought this because I work mobile and need to ensure I can be online in between clients. I have also lost work because of this issue.Complete waste of money. Very disappointed.
