I have an EB70’s and decided to run my very small slow cooker off it. I hooked up a Kilowatt meter to measure total watts drawn. The EB70s is now down to 20% only have run at 60 watts on low for three hours for a total draw thus far of 170 watt hours. This unit is rated at 716 wh, I was thinking 580 wh usable, I’m nowhere near that

I should note the unit is only three years old and has been cycled less than 25 times. And it went into the test full charge

I should add that the unit is only about three years old, has been cycled fewer than 25 times, and it went into the test at a full charge. Given those factors, the results are definitely unexpected.

I did a bit of research, and it seems the BMS needs a ‘reset’, whatever that is. I left it overnight on a 11 watt LED lamp and I’ve drawn 250wh so far, display still showing zero. I’m going to plug in a 200 watt slow cooker this morning and see what I get. Unfortunately, I will have to keep a close eye on it since the Killowatt meter zero’s out accumulated WH when the source is cut off

So I ended up with 350wh over 18 hrs. From what I understand the EB70’s has a 8w inverter draw, so that added to the 350 gives me about 494wh of total ac power. I suspect these units perform better with higher wattage loads, closer to 100 watts. Thoughts?

Try a full charge/discharge/recharge. Make sure it fully charges to 100%. Discharge at between 100W and 200W, not anything max. If the fans are running when you get down to 0%, let it rest for 5 or 10 minutes before recharging to 100%.
There is also the fact the inverter uses power. Low wattage items using AC are not as efficient as you would think.
See this thread: New EB70S.. Only get 414whr out - Defective?
I have an EB70S and the manual shows an estimated discharge chart:
Which brand of slow cooker and which model? I found this chart of various models and the wattages they use:
Sorry I can’t seem to get this to insert paragraphs. Super annoying.

The slow cooker is a 1.5 quart generic. 49 watts warm, 69 watts low and 119 watts high. I had it on low

I’m running two USB fans now on the DC side, 3 watts total, I will log that to at least test battery capacity since there will be no phantom load or minimal
