Griffin PowerJolt Reserve Backup Battery for iPhone and iPod touch


The Griffin PowerJolt Reserve Backup Battery [$34.95 - iMore Store Link] is one nifty little iPhone/iPod touch accessory, One of the biggest gripes people have with Apple's iPhone is the lack of a removable battery. Sure you have some other battery charging options but if you don't want to be bothered carrying around cords or bulky cases then the PowerJolt Reserve just may be for you. Get the full rundown after the break!

I've been using the Griffin PowerJolt Reserve for iPhone & iPod for a little over a month now and it has turned into one of those things I need to carry around with me whenever I leave the house. You simply plug it into your vehicle's cigarette lighter or 12 volt power outlet which then allows you to plug in your standard iPhone USB charging cord to charge your device while on the road.


A simple car charger alone would be on the boring side, what makes this accessory so special is that it also happens to have a built in rechargeable battery attached to it which you can carry with you in your pocket for backup power wherever you go. While it takes only a short time to fully charge, the backup battery will provide you with a 50% charge on your device. I was hoping to get a bit more but beggars can't be choosers and I've learned that it's usually all I need. Some more great features are as follows:

  • Charges any iPhone and iPod touch.
  • Charge your device the same time you are charging the backup battery.
  • The battery connects to the charger magnetically so it is a breeze to attach and detach.


The Griffin PowerJolt Reserve Backup Battery for your iPhone or iPod touch [$34.95 - iMore Store Link] is a must have accessory for any road warrior who needs that extra juice to make it through the day. With the PowerJolt you will never have to worry about battery life again and even better there will not be any need to carry your charger with you everywhere you go as it provides instant power on demand.

Roman says:

What exactly is the button with the battery on it do? I just used it for the first time today and it looks like it starts charging when it's connected. I push the button and the green lights show up. Is it just to see the battery level on the the external pack?

Scott says:

Hi I have one of the griffin gizmos and a iphone 4 and at first I thort wow this is going to be grate but after using if I'm starting to think maybe it could be a wast of money sins it only gives me about 13% extra battery power I was told at the 02 shop that this would charg my iPhone 4 at lest 40% and I made a point that I hade a iPhone 4 I really am disappointed with this I meen in a emergancy if I hade let's say 4% battery then I think if I plugged a fully charged battery in I could only make one 6 min call the backup battery should be for that extra boost wen u need it but with this I just don't think it's worth it 13% if it's not being used before the backup is depleted the battery should be for convenience not for that emergency last 10 of 15 min call to the wife
