There's a big Anker sale on Amazon that covers several well-regarded power banks and charging accessories. This includes the 737 portable laptop charger, which is just $88. That's the best deal of the bunch,

A fast power bank that conveniently comes with its own cable? Yes please! Especially now that it's 50% off on Amazon.

While it's normally $180, it can now be had for much less, thanks to a steep discount from Woot, dropping the price by nearly 40%, bringing it down to just $110. This is the lowest price we've seen on this model, and supplies are limited so you'll want to be quick if you're thinking about picking one up.
