A 1000W pure sine car inverter runs laptops, CPAP, chargers, a blender and compact coffee makers under about 800W, but not microwaves, kettles or hair dryers. It draws about 93A at 12V, so wire it to the battery. REP1000 vs REP1500.

Most 120V electric pressure washers draw 1,500-1,800W and surge 2-3x at every trigger pull. A 3000W pure sine inverter runs 13-15A washers from a van or truck; 2000W suits compact 11A units. REP2000 vs REP3000.

A typical 120V drip coffee maker is about 600 to 1200W; many single-serve pods are about 900 to 1500W. A 1000W pure sine inverter covers most drip makers under about 800 to 900W continuous; larger drip or pod machines near 1200 to 1500W need 1500W. Compare REP1000 and REP1500.

A typical 120V RV electric kettle is about 1000 to 1500W continuous; a 1500W pure sine inverter often works for kettles at or under about 1200 to 1400W, while larger 1500W kettles or dual loads need 2000W. Compare REP1500 and REP2000.

A 120V induction cooktop draws up to 1,800W, so a 3000W pure sine inverter runs it on high; 2000W works on medium. 12V current, battery BMS limits and wiring tips.

A full-size 1,500 to 1,875W hair dryer needs a 2000W pure sine inverter on high; 1500W runs a travel dryer or low heat. 12V current, battery BMS limits and wiring tips.

A 1000W pure sine inverter runs a tailgate TV, speaker, phones and pellet grill at about 500W; choose 1500W to add a blender or slow cooker. Load table, 12V current and battery hours.

Most gas furnaces with an ECM or 1/3 HP blower run on a 1000W pure sine inverter in a power outage; a 1/2 HP blower or furnace plus fridge needs 1500W. Furnace watts, 12V current and battery hours.
