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)

Good little battery, I use this every day as my charging port is broken on my phone so it has saved me a fortune on a new phone or repair 👍🏻

Bought the 10,000mAh in 2019, used occasionally over the years, dug it out again in August 2024 and it's still as good as new.This charged my iPhone twice without issue, then recharged in a few hours.Perfect for going going out for the day. Small enough to carry, and powerful enough to make it worth the effort.

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.

These are great for heating jackets that require an external heating battery. They are lightweight enough to fit comfortably in the pocket. They also can charge a mobile phone.

These are just the right size to pop into a pocket and will give your phone at least one full charge. They have a couple of different connections for charging up phones, so as far as I can see, as long as you have a charge cable for your phone, you can use one of these blocks. These have been dropped many times now, yet they are showing no signs of any damage, making me think they are well made and very resilient, but I would not go out of my way to try to break it.

It's small in length and width but it's very bulky not something you can put in your pocket as it would get in the way, but would be ok in a laptop bag

Great value for money, works well.

I have found this very useful for the two and a half years since I bought it, however the cable broke and when I used a different cable, although it appears to be charging up, there is no power from it when you plug something in to it - the lights don't light up. I am not sure what has happened to it as surely using a different cable shouldn't cause it to fail. I would however buy it again.
