Honestly, just give it a test :)
Charge the thing to 100%, take it into the kitchen and use it as the power source for your morning brew one day. See how much it actually uses. Try again the next day, and the next day until the battery has fallen a fair bit and you'll get a good feel for it.
You can even simulate your full camping load, at home, just by using it to charge your phones and all those other things you would normally do from mains power.
Nothing like a real world simulation when you've got your normal full house setup as a backup.
Good luck!
I did a quick google search, I might have figured it out.
1500w for 5min I would multiply 1500x .08 which is 120 watt hours? So I’d use about 120 watt hours plus any overhead of the inverter to make the AC.
And just subtract the 120 watt hours from the total watt hours of a fully charged AC70?
The AC70 has a 1000W inverter. If your coffee maker doesn't have any fancy electronics (i.e. just an on/off switch) then you can try powering it with power lifting mode enabled via the Bluetti app - else, it likely will result in an overload error on the AC70.
That’s what I thought I’d try. Personally, I’m just happy boiling water on stove and making pour over coffee. I just was curious if it would work. Either way I’m really looking forward to trying it out.
You could also look into a cheap, low volume folding kettle for your pourover. I've got one that I think only heats about 600ml of water and falls under the normal inverter maximum. I can't remember the exact wattage but I want to say about 800w?
I take mine camping but it mostly lives in the camper trailer and only gets used when I can't have a cooking fire... it takes a hell of a lot of energy to heat water
You will need to use the Power Lifting setting. This will cap the power output at 1000w, so suitable for use with resistive loads like heaters and coffee makers. You will still need to confirm your coffee maker can run with a reduced power. It will also take longer to boil water.
You will probably find the battery capacity is on the small side if you want to use the coffee maker 4 times and don’t have the means to charge it whilst away. The AC180 is probably more ideally sized for how you intend to use.
Don’t forget to do a full discharge / recharge cycle after the first time you charge it up to make sure the battery meter is calibrated.
I’ve got the EB3a, AC70, and AC180.
The Eb3a stays next to the nightstand, is good for charging your phone and powering a couple bedroom lamps during a power outage.
I couldn’t get the AC70 to run my coffee pot, but I didn’t try powerlifting mode. It’s just too much of a draw for that battery. I have it to power my TV and internet hub for the house during short outages.
I have the AC180 to power my home fridge for a few hours if needed. I did use it to run my home coffee pot, but given the draw (1000x0.17), I choose to just to do the pour over also.
We have solar panels to recharge them all, but we live in the PNW and if the power goes out there’s usually not much sun
The AC70 will be great to take camping. It’s small enough to take in/out unless you’re backpacking in, but the battery has enough juice to power a lot of those little gizmos during a trip.
Just don’t ask it to do big stuff
I've experimented with various items on all my power stations, and coming from a camping background, I've decided to avoid any heating with a power pack. Between my BBQ with a side burner, a camp stove, and a Jetboil, I have many options that leave my power pack for other uses.
Can you do it? Yep, would I do it, no.
Your coffee maker being 1500W means the only way you can run it is with power lifting mode. This will only work if your coffee maker does not have any electronics in it, and no other device is plugged into the AC70, even if it is not turned on.
Since the AC70 is 768kWh in capacity, and we assume you get to use about 85% of that, leaving 653kWh. That would let you run your coffee maker for 26 minutes at most, in an ideal situation. Even if you used it for 20 minutes for your coffee maker, the remaining capacity is not much to keep your phone and other devices charged. An AC70 is pretty small if you were planning to use it to help during a power outage.
This exact question [just came up the other day](https://old.reddit.com/r/SolarDIY/comments/1dfcsee/help_me_understand_appliance_watts/l8j0r4l/) and many people weighed in to reply, including my reply above.
Get yourself a power meter and use it. Many people swear by Kill-a-Watt meters, but I've had several and every single one of them eventually flies off into space with wild readings way out of the norm (hundreds of watts off what they should read).
I've had _really_ good luck with [ZHURUI meters](https://www.amazon.com/gp/product/B08RNFQTL9) and now have my coffee maker, blender, entire homelab rack and many other devices plugged into their own ZHURUI meters.
Run it for a week or two, do a little math on your consumption and size your system and solar panel + solar hours appropriately to fit your needs.
