    Does anyone want my never used charger? This was not compatible with my cell phone and did not hold a charge. My fault for forgetting about it as it was in my car's backseat. I want credit please.

    I purchased 2 of these in preparation of a power outage like last years big freeze power outage. My daughter and I both charged them, even though the package said they’d have some charge straight out of the package. We kept trying to charge our iPhones and neither one of us could get our cell phones to charge. After reading the instructions, we tried both cell phones while they were off, while they were on, we tried charging the battery packs until they were fully charged, and nothing. Unfortunately, I didn’t read the return instructions until just now and looks like I just bought myself 2 useless expensive paper weights. I’m going to attempt to take them back to Best Buy but I think I may be out of luck.

    Not worth the money. I bought one to take to Orlando with me and it didn’t even work. It didn’t charge or anything. I was too annoyed at the time to return it so I just threw it out.

    After it was fully charged and turned on, it did not seem to reliably charge my phone. Also, I wanted it primarily to supplement my laptop, hooked it up and it was not compatible despite it being 'universal' and for "USB enabled devices

    I guess it just may be a good product but I’ll never know, because the wire was missing from the package and it clearly stated no missing pieces so I’m retuning it to the store, I just opened the package 3 days ago …
