The Go Power! GP-225HD is a compact 225 watt modified sine wave inverter that changes 12 volt DC power into 120 volt AC. It plugs into a 12 volt car lighter socket with its attached cord, then gives you two standard North American outlets and a 2.1 amp USB port. It delivers 225 watts continuously and handles start-up surges up to 450 watts.
It's made for cars, trucks, vans and RVs where you want to run small AC items such as phone chargers, small lights, a fan or a camera battery charger. Modified sine wave output suits simple resistive and motor loads. For TVs, laptops on sensitive chargers and medical devices, Go Power points you to a pure sine wave model instead.
The GP-225HD has an attached DC cord with a plug for a 12 volt car lighter receptacle, so there are no battery cables to run. Plug it in, flip the switch and the green Power LED lights. Go Power's manual notes that most North American car lighter sockets are rated between 10 and 15 amps DC and are fused in the vehicle's fuse box, so check your vehicle's rating before you plug in a larger load.
The inverter supplies 225 watts continuously and up to 450 watts for brief start-up surges. Efficiency is rated at 80% or better. With the switch on and nothing plugged in, it draws 0.7 amps or less. With the switch off, the manual says it draws no current from the battery.
The front panel has two standard North American outlets and one USB port rated 4.75 to 5.25 volts DC at 2.1 amps. You can charge a phone over USB while a small AC item runs from an outlet.
An alarm sounds when input voltage drops to 10.5 volts, and the inverter shuts down at 10 volts (each ±0.5 V) to protect the battery from over-discharge. It's also protected against overload, over-temperature, over and under voltage, and short circuits. A green Power LED and a red Fault LED show its status.
A thermostatically controlled fan cools the inverter. If it does overheat, it shuts itself down and restarts automatically once it cools off. The rated operating range is 32 to 104 °F (0 to 40 °C).
Cars and trucks. Plug into the lighter socket to run a small fan or a camera battery charger while you drive.
Vans and RVs. Power small lights or phone chargers from a 12 volt accessory socket.
Road trips. Keep a phone topped up from the USB port while a second device charges from an AC outlet.
A modified sine wave inverter like the GP-225HD is a lower-cost way to run simple loads. A pure sine wave inverter is the type Go Power recommends for TVs, laptops on sensitive chargers and medical devices. The manual's troubleshooting guide also notes that some devices may buzz or show static on a modified sine wave inverter, so check with the maker of any device you're unsure about.
Go Power's spec sheet for the HD series rates the GP-400HD at 400 watts continuous and 800 watts surge, compared with 225 and 450 watts for the GP-225HD. The GP-400HD connects to the battery with cables on its DC terminals, while the GP-225HD plugs into a 12 volt socket. Both have two AC outlets, one USB port and no remote option.
Connect the GP-225HD to a 12 volt DC supply only, on a negative-ground system. Turn devices on one at a time. If the alarm sounds, switch them off and reduce the load. If you run it from a vehicle's starting battery, don't drain the battery so far that the engine won't start. Run the engine now and then to recharge, but never in an enclosed space. Turn the inverter off after use, since it uses some power whenever it's on.
Go Power's manual calls the HD inverters vehicle accessories that are not for a building's electrical system, and it says not to use them in marine applications. Keep the inverter dry and clean, give it at least 2 inches of clearance for airflow, and keep it off carpets and away from flammable materials. Don't use it for medical devices or computers. Some fluorescent lamps may not work properly on this type of inverter.
The manual says the plug fits any 12 VDC car lighter receptacle. Check the fuse rating in your vehicle owner's manual, don't exceed what your vehicle's electrical system can supply, and don't change the size of the factory fuses.
Go Power recommends a pure sine wave model for TVs, laptops on sensitive chargers and medical devices, and the manual says not to power computers or medical devices with this inverter. Choose a pure sine wave inverter for those loads.
The alarm sounds at 10.5 volts. If the voltage keeps falling, the inverter shuts down at 10 volts to protect the battery. Recharge the battery as soon as you can.
No. Go Power lists no remote option for the GP-225HD. Use the on/off switch on the front panel.
Go Power's spec sheet lists a 1 year warranty for the GP-225HD.
The Go Power! 225 Watt Heavy-Duty Modified Sine Wave Inverter gives you two AC outlets and a USB port from a 12 volt socket, with a low battery alarm, automatic shutdown and fan cooling built in. If you have questions about your socket rating or which devices will run well, the Outbound Power team is happy to help.
