Does not hold a charge, starts to lose it after about 3 days and drops quickly to nothing within hours of intial drop. Charger cable does not seat properly, and connector became lose after first charging. Button indicator broke first time pressing it. Fully charged it will only recharge a Samsung cell phone 1 time and then is almost depleted. Did not return it because didn't actually use right away, but was severely disappointed after trying and testing it. I do not recommend at any price, the mah rating has to be deceptive as it was shown through my testing of unit. I purchased at a sale price and was not worth that.
