There was a problem filtering reviews right now. Please try again later.
But it is really heavy in comparison to other chargers.
Ask yourself, will you really need to recharge your device more than once or twice?
Maybe best for international travel - given the long days, or if you need to charge phones for more than 2 people.
I'd like it better if it had lighter batter cells. Or were a bit smaller.
Dec 28th Just 3 months owned, never used. DEAD!
The product has never been used outside of being charged and stored at room temperature the week it was received.
On Dec. 28th, three months later, the power bank was dead. Never used.
Try to recharge the device and it doesn't hold a charge.
Revise: After charging for 12 hrs it was at 25% capacity (1 of 4 lights). Ended up fully draining that charge and charging again.
It appears to fully charge after about 16 hrs. Used a different USB charger so its voltage may differ from previous one.
Reserving judgement pending next recharge cycle. My other external battery (6500amh) has been easier to use and holds a charge for months.

I use my cellphone all the time when I go out, so the battery runs so fast, after I used that power bank, it just solved my problem as well, I love it.
