Portable Power Bank Chargers 10000mAh, High Capacity External Battery Packs 2.4 A 2 Ports with USB Type C Compatible for iPhone Samsung Android Mobile Phone Nintendo Switch and Tablets (10000mah)

Feels like it's working really well. It seems to do a lot of charges (for an iPhone 6s) before running out, and does charge full within a few hours (using the micro USB, haven't tried any others). It does seem that it'll only charge with the micro USB cable included - or at least I've tried 3 and only 2 work. But the ability to charge via usb, lightning and micro USB is handy. Lightweight and compact which I've found very useful for putting in my running backpack, and hanging in my dry bag to charge my phone when out walking. I have yet to use it to try charging my laptop or watch.

Useful and work as described.

This review is for:Portable Power Bank Chargers 10000mAh Model T1, High Capacity External Battery Packs 2.4 A 2 Ports with USB Type C Compatible for iPhone Samsung Android MobileGood? but how good? read on.Bought on 2 June 2022Tested this Power Bank and measured it's performance with a USB Power Meter and here are my findings.1/ fully charge it.2/ fully discharge it3/ Connected my usb power meter and fully recharged it from flat. This power bank does not charge at the rate of 2.4 amp as stated in the Specifications. I used a thick high 3 amp usb lead plugged into a charger that deliver 2.5 amp output. It only charged this power bank at 1.5 amp for the first 3 led lights, then on the 4th led light the charge slowly fell to 0.400 amps until all 4 leds were lit. At this point of full charge, my usb power meter only measured 8 ah total into the power bank battery. NOT the 10ah as stated.4/ Connected my usb power meter and from fully charged to the 4 leds. This power bank does not discharge the 8 ah that it took in to fully charge it. On the discharge test it only managed to output 6 ah.5/ So, a 10 ah power bank only takes 8 ah in and then can only gives 6 ah back out. A whole 4 ah of it's 10 ah is lost. 40% loss.(See photos)Conclusion:The power bank seams a little low on battery capacity and charge speed. It is normal for a power bank to have about 1/3 of power losses due to voltage and other power factor conversion losses. This has a full 40% of power loss from 10ah to only 6ah, so not as good as expected there.The power bank is the physical size that I wanted and has the plug sockets that I wanted. That is good.The power bank has tapered sloping sides on it making it difficult to stand on it's side to view the leds while charging without it falling over. That is NOT good.The power bank fits well in any pocket or a folding solar charger pocket. That is good.The power bank is the right weight for anyone. That is good.One las word: Cover the bottom of the case with two strips of Sellotape to protect the printed specs that is printed on it, otherwise it will wear out and all scratch off.Would I buy it again? YES.

Great little charger

I've lost count of how many of these I now have but the quality is fantastic same for battery life.Charging the power bank takes approx 3-4 hours and is more than adequate to power all my usb devices. I really like the simplistic approach (on/off, charge capacity indicator, and auto on when a device is connected) the housing is as tough as old boot which is why this power bank carries a little more weight than others similar in size. I don't reccomend having these out in the rain but even so they've never let me down in a wet environment.For basic portable power, you won't get much better value for money without any unnecessary compromise.

Took an age to charge, and is very heavy. Not a lightweight powerbank. Does, however, last a decent while once it is charged and working.

I bought this for my wife so she could charge her phone when we're out, it's absolutely great would recommend it to anyone

Works well, well madeWorth the money. Having now tested it with my other two 10000 mah power banks this for some reason lasts a lot longer. Even though they should be power
