    Bluetti / PowerOak AC200P low load inverter inefficiency, and terrible support

    Yes, I definitely would have appreciated if this information was more readily available too. 88% efficiency sounds good enough, but really that’s only peak efficiency if your load is exactly right. I went ahead and bought a 300W pure sine wave inverter and connected it to the cigarette port. So...

    Bluetti / PowerOak AC200P low load inverter inefficiency, and terrible support

    Bluetti / PowerOak AC200P low load inverter inefficiency, and terrible support

    Hi, I recently purchased a PowerOak AC200P (UK model) and I’m experiencing some weirdness with the output at low wattages. I noticed that with low AC loads, the reported load is often much higher. I bought a wattmeter to verify the actual load on the device. For example, as you can see in the...
