Proceed with caution.

Power banks are a dime a dozen these days. You’ll find them in checkout aisles and the weird sub-par electronics section at the grocery store—places like that.

They’re usually cheap, plastic, and occasionally have an inexplicable leopard print exterior. The one thing they reliably have in common, though, is that you don’t want to be plugging your expensive devices into them.

Your phone or tablet or whatever is electronically delicate, meaning your power bank probably shouldn’t be made by a company that just retooled their factory after the fidget spinner gold rush and is now getting into the auxiliary battery game before eventually pivoting to knock-off faux vintage Tamagotchis.

You want something from Aukey, is what we’re saying. They exist. They have offices. The website works (and is even updated frequently enough to have a fun Halloween theme right now). These are all things you like to see when it comes to accessories like this.

The only downside? Kinda pricey. And our retort to this, literally every time? NOT TODAY IT ISN’T.

So get yourself some serious and reliable power in your pocket for just twenty bucks. 20,000 mAh and quick charge!
