Using Old Tablet as Charger
Recycling is weird sometimes
Just a little idea I got when I was on vacation: My phone, which I use a lot, kept running out of battery and I didn't have a battery pack. However, I had my trusty ol' Android tablet with me. Tablets often have quite large batteries, this one had 4000 mAh which is about the same as a (slightly below average) battery pack. Using the host USB port, I could charge the phone when I was out. It's quite a lot bigger and heavier than a battery pack to lug around, but at least I didn't have to break my back... erm, I mean, the bank.
