Have you ever been in that situation where your massive, heavy, ‘portable’ battery pack was out of juice and your phone was too and you’re stranded in the middle of nowhere and you need to call mom and tell her you’ll be a little late to get home. No?? okay. Well this is the solution if you were ever in that situation.

All you need to do is to jump in to coles or woollies or any store that has 9V batteries for sale. Just chuck two of them in (or one) and you’re ready to charge up your phone and call mom.

Plus, I’ve always thought that backup battery packs were another device you had to charge at night. This is for when you forget to do that.
