How do I check the state of charge?

The battery icon on the LCD display shows the battery level and charge status.

What kind of devices can Bluetti AC50S power?

Please note that the AC output ports can only charge/power devices that operate at less than 300 Watts, and the gross power should be under 300 Watts as well or AC50S will shut off automatically for circuit protection. Please make sure your device is compatible with AC50S before purchase.

How do I figure out the recharge times of my device?

Working time = 500Wh* 85% / rated power of your device. For reference, assuming the device features rated power 60W (might be a laptop), the working time will be 500Wh*85% / 60w=7hrs (Estimated time). Please note: actual power consumption varies from different usages.

What is the depth of discharge (DOD)?

To prolong the battery life, the product has a DOD setting to 90%, which means that only 90% of the battery capacity can be discharged, and retain 10% to avoid damage to the battery due to excessive discharge..

What kind of battery cell is used in the AC50S power station?

A built an Auto-Level 3C rated Li-ion battery cell, it has a longer cycle time, low heat, higher discharge rate than other ordinary battery cores.

Can it charge and discharge simultaneously?

Yes, but it is not recommended to charge and discharge at the same time in order to protect the battery life.

How do I choose a compatible Solar panel?

It must meet: 1) Open Circuit Voltage (OCV): 12-40V/Max.10A, Max.120W (DC7907 to MC4 Charging cable is included) 2) MC4 Connector Tips: make sure the total OCV (open circuit voltage) is no more than 40V if you connect several solar panels in series.

Can the AC output carry a refrigerator or air conditioner?

Workable for low power, and over 100W is not recommended. The starting power of refrigerators and air conditioners are generally 5~7 times more than the rated power, which easily triggers AC overload.

How long should I recharge the AC50S power station if I do not use it for a long time?

We suggest recharging it every 3 or 6 months to better protect the battery cell and ensure a longer life cycle.

How to extend the using time of CPAP?

We recommend to turn off its humidifier, heater, and set a lower pressure.
