I've been playing with a Duo Plus Mini three quart Instant Pot (IP) lately. Sadly not the cute new Baby Yoda model, but the plain silver 700W
version. Working with the 6qt or larger IPs may be too large a draw on many inverters and battery banks, but the tiny 3qt not only fits better in the [email protected]
but uses far less power. And smaller food or water volumes also results in faster food prep times... and thus even less energy.
It only uses 1W when not heating (but with the display on). And many common recipes involve a heat cycle of 4-10 minutes to come up to pressure, then just a few minutes at pressure, after which you can turn it off or leave the 1W timer running until it naturally loses pressure over 10-20 minutes. Or you can just turn it off and wait for the pressure indicator to drop (if the recipe doesn't call for a quick release and all that sudden rush of steam and potential condensation in the camper).
If you have a 400 BD battery bank with solar, or have added a couple batteries to your 320, and in either case added a 2-3 roof or suitcase panels to your rig... you have plenty of juice for the IP.
The following three measurements were made using cold water.
Example 1. Frozen Mixed Vegetables. 8 oz of frozen veggies in a steamer basket. Enough water below for steaming. 3 minute steam cycle. 2 minute rest then quick release. 100Wh of energy used.
Example 2. Steel Cut Oats. 4 oz oats, 12 oz water. Pressure for 6m, natural pressure release. Also 100Wh.
Example 3. Beans n Rice. Can of rinsed chili beans, handful of corn, 1 cup of mixed rice, 1.2 cups of water, capful of fajita marinating sauce, dry spices. Pressure for 4m, natural release. 120Wh. (bigger quantity of food)
To put those numbers in perspective, the battery bank in the [email protected]
that is kind enough to host me has 2,800Wh of usable energy. And it has 300W of solar panels on the roof, which on a good day yields 1000Wh. In winter, or in clouds, it's half that or less. So my setup is slightly above bone stock average, but not unusually so. And typically one IP session a day is only 10-25% of the available juice.
Everyone has to do their own power budget for their rig based on how much fridge power, fans, or laptops they use. But even the tiny 3qt cooker makes enough food in 20 minutes to last two or three days for a solo traveler.
And one way to lower the electricity some recipes need by half is to pre-boil the water. If you have propane, it only takes a couple minutes to bring a cup of water to boil on the stove. Add that to the IP with the dry ingredients and the energy on some dishes drops to 60Wh
