Design – attractive, compact, handy; has a good grip.
Performance – as described. Charging is quite fast. It has auto off mechanism when your mobile battery is fully charged, or when you disconnect the load (mobile). Haven’t checked the exact capacity, but I can charge my moto g 5 several times.
Customer service – can’t comment now. Haven’t had the reason to contact customer service; hoping that I don’t have to.
Verdict – a dependable compact power house. Go for it.
If at all looking for a con in this, then I think the weight is bit heavy (not much but yeah little which is manageable ).
Almost 6 months of use and the battery capacity has somehow reduced. I have a note 8 which has a 3300 mah battery. I can charge my note 8 0-100% only twice. The power bank just dies after that.
Very very disappointed
Avoid buying. There are better options there.
Also it charges very slowly. So keep that in mind.
It takes around 7-8 hours for getting fully charged and the 4 blue LED indicators blinks to let you know the status of charging. Which is also a good night lamp. One hack I found is that you can purchase a USB LED laptop light and plug-in to get a nice emergency lamp too. Overall I recommend the product. I personally believe this product is better than the Ambrane, Intex, Mi and Huawei power banks.
Update : Jan 2019, Still works without any problem.
2 days backup for 2 phones
good build quality
soft touch body - non slippery
LED torch bit dim
Battery capacity indicator is NOT screen (as seen in image) but simply numbers backlight by individual LEDs
