Frequently Asked Questions

Can this power sensitive electronics like laptops and medical devices (CPAP)?
Yes. It features pure sine wave technology, ensuring smooth and stable power delivery identical to grid power, protecting your sensitive equipment from damage.

Can I use this unit while it is being charged (Pass-through charging)?
Yes, this unit supports pass-through charging. It can act as a reliable UPS (Uninterruptible Power Supply), seamlessly supplying power to your devices while plugged into the wall.

How long will it hold a charge in storage?
Thanks to its advanced Battery Management System (BMS), it has a low self-discharge rate. We recommend charging it to 80% every 3 to 6 months to maintain optimal battery health.
