These days, so many of our devices are charged and powered by USB chargers. I've gotten to the point now that pretty much everywhere I sit, has a wireless charger pad or a charge cable. And I mean everywhere. I have a ton of these things. Well worth it. I shopped around with a lot of different options and I'm really hooked on the quality of the Anker stuff.
Be really careful with the wall chargers out there. Some of them overheat really easily. The Anker has been the only one so far that works well.
