At A Glance


500Wh Li-on battery – 300W continuous / 450W peak power.

4-Mode Charging

Options to recharge to suit wherever you may be, indoors or outdoors.

Light & Compact

At 13.6lbs, you can take it almost anywhere away from the grid.

Multiple Ports

All the ports you need to power your devices and a 12V regulated socket.

300W continuous and 450W momentary surge power

High capacity 500Wh lithium battery cell provides you with plenty of power outputs to keep a wide selection of devices powered and charged (within its 300W rating), such as drones, camera equipment, laptops, phones, and more.

Perfect for indoor and outdoor use

Relatively lighter at 13.6lbs and compact measuring 11.6 x 7.5 x 7.7 inches this is just the sort of independent clean power free for dangerous fumes and noise you can have on standby in the home in case of a power outage so you can keep some basic essentials going. Outdoors, it would be an excellent companion for campers and those travelling long-distance by road.

Plenty of ports and outlets

A good variety of outputs are built into the AC50s, which include:

2xPure Sine Wave AC household outlets
1xPD 45W USB Type-C port
4x5V/3A USB Type-A port
1xRegulated 12V/10A car port
2x12V/3A DC ports
1X10W wireless charging pad


You have 3 +1 ways to recharge the AC50s, including the possibility of using a portable generator. These are AC wall outlet, car adapter, or the optional but recommended solar panel (the Bluetti PV120 (paid link) is an ideal partner).

Charging efficiency is greatly improved by the incorporation of MPPT, and when necessary the battery cell is cooled by an intelligent cooling system. Battery safety is further ensured by a Battery Management System (BMS) to protect you from any potential failures, such as overheating, or short-circuit.

Frequently Asked Questions

What can this device power?

The AC output ports can only charge/power devices that operate at less than 300-Watts. The total wattage of both outputs must also be under 300watts. Once exceeded,  the AC50 will shut down automatically. 

How long will AC50S power my device?

You can estimate the working time with this formula: 500Wh x 0.85 / operating power of the device, bearing in mind that actual conditions may vary this result (0.85 is the Conversion Rate).

Can I use a 2 Solar Panels in parallel?

Yes, you can use 2 Solar Panels in parallel provided that the total open circuit voltage (VOC) is between 12-40V, Max.10A and a maximum of 120W.

Can I take this power station on a plane?

No, the Li-on battery size exceed that permitted by the TSA for safety reasons.

Can I use the power station while it is on charge?

Yes, it outputs power even when the unit is being charged. However, charging the device will take longer and may reduce the life of the battery.

What does depth of discharge (DOD) mean?

DOD is the % of permitted battery discharge to avoid damage to the battery. It is set to 90%, and will never go below maintaining 10% on the AC50s.

Can I link two AC50s devices together like other inverter generators?

No, you cannot link two AC50s in parallel.
