Hello everyone, My name is Thomas, I’m 66 and I’m very new to using Bluetti devices. I have two units the EB3A and the Elite 100. My questions center around battery usage and how much the battery seems to discharge during usage.
Example 1, on the EB3A: I was charging my Samsung A series tablet 2 days ago (the EB3A was at 100%, the tablet was at 5%) and was also using it to watch some videos. The battery went from 100% to 84%. Then yesterday, charging the same tablet (which was at 14%, powered down and not being used) the battery went from 84% down to 50% and only charged the tablet to 80%. This is the part I don’t understand, why so much more battery usage the second time around.
Example 2 is with the Elite 100: The battery on the elite was at 48% and I needed to use it to boil water for my coffee (there was a short power outage here at the time). Using a 1500 watt electric kettle the battery went from 48% down to 8% in just a few minutes and the water didn’t even come to a boil.
I know I’m new to this and I don’t yet understand how these portable power systems work so I really want to understand why the batteries seem to drain so fast and if it is all supposed to work this way.
Thanks for reading this and thanks for your help and guidance. I apologize in advance if I’ve posted this in the wrong place.
Cheers.
My first thought is Calibration. You need to do this, then re test consumption. It may be that what showed on the display was not correct.
To calibrate either power station, put a constant modest to medium AC load on each until the power station battery shuts down when fully discharged. Then recharge it from the grid via AC in Silent mode, to be kinder to the battery, until it is at 100%. Do this without DC or AC loads connected and with those output switches in the OFF position.
Constant charge/discharge cycles eventually caused calibration to “wander”. I do this to all my power stations every 6 months regardless and if something seems odd, at that time as well. If it keeps happening, then there may be an issue with the power station, even, possibly the device you are powering.
Thank you so much for your response and for teaching me about calibration. I will do this and see if anything improves.
Thanks again.
