waste of money

i bought this power bank a year ago, only used it about 3 times, and it doesnt properly charge my phone and now it doesnt even recharge. it took so long to fully charge my phone and it used up all its battery to recharge just 1 phone. I regret buying this and wasting my money on this.

Needs some improvements when it comes to charging the device

Device works great for recharging other devices but when it comes time to actually recharge the unit it self there is definitely some flaws. Cord barely stays in place. Have to constantly readjust it to get it to charge. Also was using my regular power adapters for my cell phones and fried them all because I was unaware that it required a higher voltage. They should probably include the correct power adapter cause not every user has access to computers and such all the time. Just my two cents.

Waste of money

I bought this only four months ago and it has stopped recharging. The cord won't even stay in place firmly enough to make a connection. Waste of money.

It delivers !

I bought one a few months ago and I use it for my iPad. No issues. Charges my Windows & iPhone fast. It's true that the IN connector can cause the cable to fall out..but it's not really an

Bought the unit because my phone was almost dead. Worked great for charging the phone once, but I was unable to recharge the battery. Don't recommend this at any price.

Gets the job done, but has flaws

Overall this product is good enough for the everyday user. It'll hold a charge for a while and can charge most new phones at least once over, if not twice. The addition of an LED flashlight is interesting but I won't question it. The design suffers one major flaw, however: For whatever reason, the devices microUSB port lacks grooves that prevent the cable from falling out, which essentially means that the USB cable will fall out EXTREMELY easily when charging the device.

Retrak 8000 mAh Power Bank - Black

Ordered online- what was delivered says 7800 mah not 8000 , online also states life time warranty on parts yet box delivered says limit 1 yr warranty , i guess you should really shop in store if you want to be sure what your getting.

Works as promised. Been using this for about 3 months now, with not a single issue. Actually considering purchasing another unit just incase. So buy one, and you won't be let down.
