Suaoki via Amazon offers its Suaoki 20,000mAh Portable Battery Pack / Power Inverter for $209.86. Coupon code "IHG87OVZ" cuts it to $159.49. With free shipping, that's $11 below our mention from three weeks ago, $50 off, and the lowest price we've seen. It features two AC outlets, two DC outlets, and two USB ports. Deal ends December 15.

Note: While the seller calls it a generator, it's really just a large power bank / power inverter that can be charged via a wall or car power adapter (both included) or solar charger (not included).
