DieHard 425W Power Inverter – Modified Sine Wave Car Inverter

For a low budget, the DieHard 425W power inverter can be the best alternative. The 425W power is perfect to charge several devices like gaming consoles, laptops, cell phones, televisions and small appliances.

The DieHard inverter is easy to install in vehicles because it is especially made for vehicle usages. For a handy use, the 425-watt inverter is a solid and medium-sized unit. That means the modified sine wave inverter is perfect for cars, boats and RVs.

Just like RV inverters on the market, the DieHard inverter converts 12V DC battery current to 110V useable current. Thus, you can use the 110V current via two outlets to charge your preferred devices.

Protection – the DieHard 425W inverter has competences such as temperature shutdown, overload protection and several other protective features. Additionally, the power inverter comes included with accessories such as 12-volt plug, battery clamps and ring terminals.

Output power – the DieHard inverter delivers modified sine wave power. It delivers 425W continuous and 850W peak power. In fact, some appliances require startup power, which is more than normal. Therefore, the peak power is very useful in that condition. Please note that peak power remains just for few seconds, after that the inverter supplies continuous power. In this inverter, 425W is continuous power.
