This little thing is awesome. It's so small and lightweight, it's shocking how much capacity it has (540Wh). It can handle a peak surge of 500 watts. Plenty of USB plugs for charging multiple phones, and the AC output can run laptops, small appliances, and pretty much anything 300 watts or less. I've plugged in heat lamps, coffee grinders, a small blender, LED lighting, the works. SUPER Quiet operation as well.

I'm currently using this as a battery backup for my fish tanks to be able to run their pumps and heaters during a power outage. Lasts longer than some of the UPS backups I've had and it's 1/20 the weight!

This is my first WANROY product! As a retired electrical engineer, after 6 months of use, I summarize some interesting content:
First the cardboard outer packaging and well-designed product box provide fantastic shipping protection (looks great!)
Both buttons/connectors and LED display are high quality and work well
The LED display has 5 bars (each bar shows 20% battery)
Best value 500 watt output on the market + light weight for me to take to camping
