senymin (3 packs) Lighter-Size Portable Charger the Smallest and Lightest Power Bank, Ultra-Compact External Battery, Compatible with iPhone 12/Xs/XR, Android smartphones, etc(Black&White&Pink)

I bought a pack of these perfectly powerful little batteries and some sticky backed velcro when faced with the vive battery shortage.They fit perfectly snug to the strap, are lightweight making them unnoticeable when wearing and have a longer battery life than the official vive batteries.This pack of three batteries comes with a tiny cable for each one, the perfect length for the trackers.For less than the price of one official vive tracker I have yet to see my trackers fall below 100% power even during an 8 hour play session.This item is so good that I bought them twice so I'll always have a spare.I cannot recommend this enough; great value for money.

I’m very impressed by the size - it really is small and light! Exactly what I was looking for. It does last longer than expected, and gives my iPhone 12 Pro a full charge (not sure how much more as I have only charged it once).Negatives:– Fairly slow at charging my phone (but difficult to say whether that is due to the charger or the cable).– Expensive. The ‘get three for the price of one’ is simply not true. Each charger is only 3000 mAh, and a 1000 mAh charger is usually around £10-16. No way would a 3000 mAh charger cost £23.– Should be possible to buy just one, or two. Feels like a bit of a waste getting three, as I don’t need that many.

Hi this is shown on picture as being compared to the size of a classic lighter .. it is 2-3 times wider .. very thick ! Thickest charger I’ve purchased ., thicker than a 20000 ma charger .. a lot longer and wider , does not fit in hand as portrayed .. a lot more bulky ., very misleading .

Not brilliant, only really wanted a small one for a heated scarf for my mum. These are very cheap looking and the build quality is not to be desired.Charge and work ok, but only really work on things that don't use much juice.I wouldn't really recommend.

Very cute. The pink one even comes with aPink cable. Quite handy。one fully charged can charge HuaweiP3 upto 55%. One set has three of them,so if one is not working I still have another 2. I think it's good:)

States has usb, lightning and type c charger cable...lie. has micro usb only, I wouldn't gave purchased if I had known.

Great compact power banks. Almost 1 charge from them but ideal for having with phone in pocket or bag for emergencies

The product was very good.It is easily transportable and has a very long charge time which is very convenient.Overall, I would recommend!
