For Christmas I'm looking at getting my wife an external battery/power bank to charge electronics on the go. I think she would use it frequently for charging her phone or a tablet my kids tend to use a lot. Having said that, I'm ready to move on from my cheap no-name solar battery pack I take into the backcountry so i'd like to get one for her that I could borrow for that application as well. Two birds with one stone, right? I know I'm an awful spouse.... Anyway any of you have any recommendations on a specific brand and or model to check out? Any to avoid? I think I want at least 10,000mAh to charge a tablet and that would get me a few charges on a phone. Any help is appreciated.
