It is one of the most common questions people ask before buying a car inverter, so let us answer it plainly: a 200W inverter will not run a normal fridge. But that does not make it useless — far from it. It runs a surprising amount of what you actually need on the road.
Why a fridge is off the table
A fridge might only draw 100–150W while running, which sounds within reach. The problem is the startup surge: when the compressor kicks in, it briefly pulls three to five times that — often 600W or more. A 200W inverter simply cannot supply that spike, so the fridge either will not start or the inverter shuts down to protect itself.
What a 200W inverter runs beautifully
- Laptops — most use 45–90W; ideal for work trips.
- Phone and camera chargers — a few watts each.
- Wi-Fi routers / dongles — for a mobile office.
- Small USB or desk fans — low draw.
- LED lights — for camping or roadside work.
The rule is simple: add up the wattage of what you want to plug in and keep the total comfortably under 200W.
Why pure sine wave matters
Cheaper inverters output "modified" sine wave power, which can make sensitive electronics buzz, run hot, or fail over time. A pure sine wave inverter delivers clean power just like a wall socket — safe for laptops and cameras.
If your need is powering electronics on the go — not running a kitchen — the EchoRepel 200W Pure Sine Wave Inverter plugs into your car's 12V socket and gives you clean, reliable power for exactly the devices most people carry.
