There are plenty of portable chargers out there, but we doubt you’ve ever seen one quite like this. Despite its compact and lightweight form factor, the ZMI USB PD Portable Backup Battery & Hub packs a massive 20,000 mAh battery that can charge all of your gear on the go. And when we say “all,” we really mean it. Whether you want to power something compact like a smartphone or Kindle, or you’re looking to refuel something larger like a Nintendo Switch or even your MacBook or Chromebook laptop, this handy gadget has you covered. It comes from a trusted brand — ZMI has sold more than 80 million portable chargers over the years — and it’s a bargain at $69.95 considering how much use you’ll get out of it.

Wait, did we say $69.95? Use the coupon code B9TRJ754 at checkout, which is exclusive to BGR readers, and you’ll save $20! That drops the price of the ZMI USB PD Portable Backup Battery & Hub to a nickel under $50, which is an absolute steal.
