AnkerDirect (99% positive in the last 12 months from 15,0937 ratings) via Amazon is offering the Anker PowerHouse Compact 400Wh/120,000mAh Portable Outlet-Generator for $399.99 shipped. That’s $100 of the regular price, matching our previous low and the best we can find.

The PowerHouse is “an off-grid power supply” that works great on camping trips, during power outages, or just for some extra juice for your phone, laptop, TVs and more. Rated 3.8/5 stars from over 50 customers.

If this is a bit pricey for you, a lesser expensive solar option might do the trick.
