-[personal note from secessus:  Electrical appliances like crockpots are plentiful and cheap at thrift stores.  Check the wattage on the bottom/label.  Removable crocks are somewhat less important in a vehicle context since we have no dishwasher to remove the crock //to//.]
+Analog cooking appliances (knobs, not electronics) run fine off inexpensive MSW [[electrical:inverter|inverters]].
-Note:  instant pots typically require more power than 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.
-> The [[https://amzn.to/3kyxFjw|3qt model (mini)]]... draws less wattage at 700W versus 1,000W for [[https://amzn.to/3ystbjj|the 6qt]] and 1,200W for [[https://amzn.to/3sQDxbC|the 8qt]]. -- loveyourrv((https://www.loveyourrv.com/instant-pot-boondocking-power-draw/)) {[[https://amzn.to/3jtf9tT|the 10qt]] is [[https://www.pressurecookingtoday.com/instant-pot-duo-nova-review/|1,440w]] -- secessus}
-.  See below for alternatives.
   * Normal sized [[food:cooking:crockpot|crock pots]] typically take 125w-200w on HI and half that value on LO.
   * **mini rice cookers**.  Normal rice cookers run ~300w but some of the smaller travel ones use less.  Example:  [[https://amzn.to/3h7bt03|Dash 200w 1L travel rice cooker]] (**200w**).
   * immersion (loop) heaters for AC are typically 300w although NOS((new old stock)) versions can be found for 200w.  Example:  [[https://amzn.to/3f0RRI1|Norpro 559 immersion heater]]. (300w)
   * [[https://amzn.to/3rfwgC2|this two-burner hotplate]] has a 600w coil on one side that may be usable in a van.
+  * small 120vac lunchboxes, as for bento.  Example:  [[https://amzn.to/3lk9Gp8|FIKNEE lunchbox heater]], rated 200w and [[https://vanlivingforum.com/threads/japanese-electric-lunchbox.46157/|used by Psyckosama]].

-=== crockpot vs instant pot ===
-Instant Pot advantages:
-  * 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]]

 ==== breaking the 10A barrier ====
-[[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))
