I've had one sit in a drawer for 30 days and still hold 90% of the charge.
Sorry, there was a problem. Please try again later.I have kept a fully charged Dynex in my car for a trip of 9 days. We used it at the end of the trip, and it was able to charge my iPhone from <20% to 100% full charge. I do not know if it could have charged anything else after that (didn't try). Hope this helps.
Sorry, there was a problem. Please try again later.Not sure of how long it will stay charged but if you charge your cell phone the charger needs to be recharged after that. It's good for one charge before needing to be used again.
Sorry, there was a problem. Please try again later.My husband's worked last night. His hasn't been recharged since Christmas day. I don't know if this helps or not...
Sorry, there was a problem. Please try again later.Dynex must be fully charged and you will get about 6 hours depending on your phone and the battery inside the phone itself!
Sorry, there was a problem. Please try again later.Should hold a charge for a long time we haven't had any troubles
Sorry, there was a problem. Please try again later.This device charges about 2 to 3 iPhone 6's. depends also on how long you charge them We used them in Mexico and took a wall charger along with us and charged them that way. But we always had the Dynex with us. It was great.
Sorry, there was a problem. Please try again later.I have kept mine in my purse for days and it gave my phone a charge. I don't know if they are different, but that's how mine worked for me. Keep you charger cord with you, so if you have to charge it you can. After use of course.
Sorry, there was a problem. Please try again later.not sure but I sometimes wait about 4 hours before I use the charger and it will still charge my phone to the max quickly.
Sorry, there was a problem. Please try again later.Mine only lasted about 10 minutes
