PRODUCT DETAILS
The Go Power! GP-ISW200 is a compact 200-watt pure sine wave inverter for laptops, chargers, CPAP machines and small electronics — clean household-quality AC from a 12 V battery with dual GFCI outlets and a powersave mode that keeps idle draw low. It is the smallest of the Industrial Sine Wave family and the easy choice when you only need to run a few small devices.
Built to the standard RV manufacturers install
Go Power! has designed mobile power since 1996 and is the inverter brand fitted at the factory by Jayco, Forest River, Thor and other leading RV builders. These previous-generation models are sold here at outlet pricing while stock lasts, with the same 2-year warranty and the same North American support team (part of Dometic). For the current lineup see the Smart Sine Wave and Advanced Sine Wave inverters.
FEATURES
- 200 W continuous / 250 W surge pure sine wave — safe for electronics.
- Dual GFCI outlets.
- Powersave mode cuts idle draw when nothing is plugged in.
- Full overload, short-circuit and temperature protection.
- Compact: 5.6 × 5.2 × 2.4 in, 3.5 lb.
- 2-year warranty + North American support (part of Dometic).
WHAT IT RUNS
Size by the continuous rating and leave headroom for start-up surges. Typical draws: phone/laptop 20–90 W, 32 in TV 50–80 W, CPAP 30–60 W, blender 300–600 W, coffee maker 600–1,000 W, microwave 700–1,200 W (1,000–1,700 W input), hair dryer 1,200–1,800 W. A 200 W inverter draws about 19 A from a 12 V battery at full load, so a 100 Ah 12 V lithium bank runs it flat-out for roughly 5.2 hours.

ACCESSORIES
FAQ
What can a 200-watt inverter run?
Anything whose running watts stay under 200 W and whose start-up surge stays under the surge rating. Laptops, phone and camera chargers, CPAP machines without a heated humidifier, small TVs.
Pure sine wave or modified sine wave?
Pure sine wave is the same clean power as a wall outlet and runs everything — TVs, laptops, CPAPs, induction cooktops, microwaves — quietly and at full efficiency. Modified sine wave is a stepped approximation that is fine for tools, lights and resistive loads but can buzz, run hot or damage sensitive electronics and some chargers. This model is pure sine wave.
Which install kit do I need?
GP-DC-KIT1 (60 A fuse, #6 AWG) covers 200–600 W inverters. See the install kit guide.
How do I switch it on and off remotely?
Add the ISW Inverter Remote (25 ft cable). It gives you on/off, a battery-voltage and output bar graph and fault indicators where you live, and works with all GP-ISW inverters.
How big a battery do I need?
Figure amp-hours from watt-hours: a 200 W load for one hour uses about 17 Ah from a 12 V bank. Lithium can be drawn to near empty; AGM should stop around 50%. Keep the inverter within a few feet of the batteries and use the cable gauge from the install kit guide.
Is this a current model?
This is a previous-generation Go Power! inverter sold at outlet pricing while stock lasts. It carries the full 2-year warranty and North American support. The current series are the SSW (hardwire and outlet) and ASW (built-in transfer switch) inverters.
Is Go Power! the inverter installed in my RV from the factory?
Very likely, if your coach is a Jayco, Forest River, Thor or one of many other brands — Go Power! has supplied RV manufacturers since 1996, so these are the same products and the same support team your dealer uses.
What is the warranty?
Two years against defects in materials and workmanship, backed by Go Power!’s North American support team (part of Dometic).
