01 — 300W pure sine wave
Two 110V AC outlets deliver 300W (375W peak) of pure sine wave power for laptops, fans, lights and small appliances, alongside a DC output. It is the size of a lunchbox and weighs 4.6 lb, so the backup box lives in a closet, not a garage corner.
02 — Five USB outputs
Five USB outputs cover the whole family's phones and tablets at once: two QC3.0 USB-A ports (18W max), two standard USB-A ports (15W max) and a USB-C PD port (18W). Everything charges from one box instead of a strip of adapters.
03 — Wall, car or solar in
Refill it from a wall outlet in about 6 hours, from a 12V car adapter in about 8 hours, or from a compatible solar panel (DC 16.4-24V input, panel sold separately). Two built-in LED lights — one with an SOS mode — mean it lights the room while it powers it.
How it works
Fill it from a wall outlet (about 6 hours), a car adapter (about 8 hours) or a solar panel.
The battery gauge shows the charge state; store it topped up so it is ready when needed.
When the power goes out or the tent goes up, plug in AC and USB devices up to 300W total.
