TNTOR5000mAh mini Power Bank, Ultra-Compact Portable Charger with USB C Input/Output, External Battery compatible with iPhone Samsung Galaxy and more (Black)

Very handy as can take USB A and USB C. Small enough to throw in bag and large enough capacity to get a decent phone charge from

Compared to my other power banks, this is one of the lower capacity ones which has a total of 5000mAh. This is more than enough to provide 1 full charge at the very minimum to the majority of the smartphones currently available.I've previously owned a TNTOR power bank and this mini one is quite a bit smaller but it's also chunkier.Another difference is that this is not QC compatible so it charges phones at a slower rate. However, this is perfect for my intended use as I only needed something with a small capacity to put in my car for emergencies as my car charger is used by passengers and there is only one cable.At £9.99, it's good value and has two ports that can allow you to charge two devices at the same time.All in all, exactly what I needed. As I've owned TNTOR power banks before, I know that they are reliable given the fact that my previous ones are still going strong!

I've always test batteries methodically since they vary so much in terms of actual vs claimed capacity, charge rates etc and some just need sending back. This one charges/provides power at the rate they advertise, supports pass through charging, can provide charge from either USB A or C port (or both at the same time), included USB C cable works ok, and weight is correct (97g on my scales). But actual capacity is as poor as cheap'n'nasty brands from years ago ... 77% of that quoted (i.e. 14.25 Wh vs the 18.5 Wh you'd hope for, so you'd market it as '3850 mAh' rather than '5000 mAh), when plenty of brands come up with as much as 95%. Build/finish quality is ok but a bit 'so-so' compared other ordinary/cheap brands I use (Iniu, Anker, easyAcc, Nokia). Charge efficiency (i.e. losses from the built in electronics) seem as good as anything, so it's the lithium cell that's poor, which also casts doubts as to how long it will last, but of course that's just conjecture for now. If it had been advertised as 4000 mAh (say) I'd have felt satisfied: the point is more compactness than capacity, and weight/volume is still fairly good for actual capacity.

Quite a good charge

It's nice a small which makes it very portable, but charging power was disappointing, as there wasn't enough power to recharge my phone from 22%. It only got to 85% which took 90mins, however it's handy to have as an emergency top up given its small size.

At first i thought these where compact and useful but both modules died almost immediately and never turned back on, dodgy product

Dimensions looks to be advertised so its a small form factor, with a bit of weight to it. LEDs showing charge not very big or bright but do the job. The USB B port is output only whereas the C port is 2 way. Short cable and mesh carry case included. Comes in a fairly premium looking packaging box. All seems fine. You will probably notice the weight if you have it in a pocket but not impossibly so. But if you plan on keeping in a bag it may make sense to go for a larger output, as 5000mAh is likely to be only around one charge of your phone - fine for me as bought as backup (eg on a day when using google maps a lot) rather than routine use. Giving a 4* review as nothing very exciting about any power bank that would warrant 5* but can understand why others might give 5*. A micro USB B port for my older cables/devices might have been useful at the margins.

It’s charging my iPhone extremely slowly. For +10% it take 30m… Also to re-charge it expect an entire night. Not great
