FAQS

  • Q1: What devices can I power using the BLUETTI AC50B?
    A: The AC50B is capable of running devices up to 700W. It also features a Power Lifting mode designed for up to 1,000W pure resistance devices, like electric kettles and irons.

  • Q2: How long will the AC50B power my devices?
    A: Operation time = (448Wh x 0.9 x 0.85) ÷ (Load Power + 10W)
    AC50B's battery capacity: 448Wh
    Depth of discharge: 90%
    Inverter conversion efficiency: η = 85%
    AC50B's self-consumption: 10W

  • Q3: What kind of solar panel should I choose?
    A: To ensure optimal performance with your BLUETTI AC50B, select a solar panel that meets the following criteria:
    1. Features MC4 interface.
    2. Voltage range should fall within AC50B open circuit voltage (OCV) of 12-28V.
    We recommend 1 × BLUETTI PV120 / PV200.

  • Q4: Why does this power station lose charge even with no devices connected?
    A: The AC50B consumes a small amount of power in standby mode due to the AC inverter, DC regulator, and LCD screen. To prevent this, long press the AC/DC Power Button to completely shut down the unit when not in use.

  • Q5: Why is the AC50B heavier or larger than competitors？
    A: The AC50B is designed to balance durability and safety, which may result in a slightly heavier product. Key factors include:
    1. Higher Power Output: The AC50B offers a robust 700W output, compared to the typical 500W of many competitors.
    2. Quality Components: The AC50B uses high-quality components like heat sinks, inductors, transformers, and fans, which enhance stability and performance but may add to the size and weight.
    3. Solid Design: The integrated handle on the top cover provides better grip and load-bearing capacity.
    4. Double-Layer Battery Protection Structure: This design enhances impact resistance, ensuring the AC50B can withstand tough conditions.

  • Q6:  Most competitors offer both WiFi and Bluetooth control via an app. Why does AC50B only offer Bluetooth control?
    A: According to our research, low-power devices like AC50B are typically used for short-term outdoor activities or emergency situations at home, where users are usually nearby. To maximize cost-effectiveness and efficiency, we chose Bluetooth control, which provides reliable and convenient local connectivity without unnecessary complexity.

  • Q7: Why does the AC charge quickly up to 80% but slow down for the remaining 20%?
    A: Rapid charging over extended periods can accelerate battery capacity degradation due to instability in the chemical reactions within the battery. This affects the cycle life and energy density of the battery. To extend the lifespan of the LiFePO₄ battery, the AC50B is designed to charge quickly up to 80% and then switch to a slower charging rate for the remaining 20%. This strategy balances charging speed with battery longevity, ensuring efficient operation while maintaining a longer usage cycle. The Battery Management System (BMS) dynamically adjusts the charging current to optimize battery health and safety.

  • Q8: Why does the AC50B advertise a 0.02s UPS switchover time, while competitors advertise a 0.03s?
    A: The AC50B meets the standard for standby UPS and has been rigorously tested to ensure it can switch within 0.02s. This rapid switchover time ensures that your devices remain powered without interruption, providing a seamless and reliable backup power solution.
