| * carry extra fuses in case you blow the ciggy port fuse |
| * unplug before removal from water to avoid overheating the element |

[[https://amzn.to/3LmlZMs|Instant Pots]] are becoming increasingly common as some [[electrical:12v:intro|vandweller power systems]] become beefier. While convenient, they are effectively electric [[food:cooking:cookware#pressure_cookers|pressure cookers]] + [[food:cooking:crockpot|crockpots]], both of which are much less demanding of power.((traditional pressure cookers are heated on the [[food:cooking:stoves|stove]])) | Analog cooking appliances (knobs, not electronics) run fine off inexpensive MSW [[electrical:inverter|inverters]]. |
| |
Note: instant pots typically require more power than most vehicle-dwellers have on tap, but [[https://www.reddit.com/r/vandwellers/comments/7nyvos/instant_pot_yay_or_nay/ds5ntc6/|it can be done]] if one understands the issues. | * [[food:cooking:crockpot|crock pots]] typically take 125w-200w on HI and half that value on LO. |

=== crockpot vs instant pot === | === crockpot vs instant pot === |
| |
| There are some major ways the two differ: |
| |
Instant Pot advantages: | * cost - used crockpots are cheap in thrift stores |
| * current - crockpots demand much less current, which may also increase the cost of wiring, batteries, and [[electrical:inverter|inverter]], but... |
| * energy use - instant pots will generally use far fewer watt-hours to took the same meal((due to better insulation, temperature control, and pressure cooking)) |
| |
* much faster cooking times possible | |
* temperature control (heating element runs as needed)for more accurate cooking and reduce power consumption | |
* better insulation will likely reduce power consumption | |
* pressurized modes will result in consistent cooking at high altitude | |
| |
| |
Crockpot advantages: | |
| |
* much lower cost, particularly if bought used at thrift stores | |
* much lower current demand (150w vs 1000w), which means a crock can run on components that cost 1/6th as much | |
* analog crocks (physical controls, no digital components) run happily on inexpensive [[electrical:inverter#msw_and_electronics|MSW inverters]] | |

[[electrical:12v:ports|Ciggy outlet]] power is typically limited to 10A (~120w). | see [[electrical:12v:alternator#isolator_without_a_house_battery|this article]] |
| |
If you wanted to extract more power from the alternator you could wire in [[electrical:12v:alternator|an isolator]] (plain solenoid or VSR). Instead of feeding an auxilliary battery this isolator would be used to pull more current into the living area. You could run 12v loads directly, or attach an inverter's input wires to the isolator's outputs.((positive to isolator, negative to chassis ground)) | |
