Lots of juice
When it comes to power banks, something is better than nothing. If you’re just trying to resuscitate your phone from the brink of death so that your family doesn’t think you’ve been eaten by wolves or something after you abruptly cease communicating with everyone, most power banks can do the trick.
This one, though?
This one does more than that.
It’s not the cheapest thing you can buy, but with 20,000 mAh on board, you’re not just talking about buying yourself an extra hour of battery life. You’re talking about taking your phone from 0 to fully charged, multiple times if you need to. You can power a tablet. You can power a laptop.
It’s a serious power bank for delivering serious power. Still just 40 bucks.
