instaCHARGE Grab & Go 4-Pack 4000mAh Power Banks & Charging Station (Silver)

It doesn't hold a charge long. It doesn't power long.

A friend of mine received this as a gift. So I know it was great before I received mine. I would like to order more for gifts. Please get this back in stock:)

Waste of money. None of them will give a full charge on my phone. Too much wiggle room in the charging dock.I can see one being bad but not all 4.
