If your breakers trip while running appliances at the same time as your AC, this soft start will keep your AC from drawing too much power at startup. It includes a 30-amp adapter and even lets you run two units on your 50-amp RV at the same time.
A soft start device reduces the initial inrush current when an AC compressor kicks on. Instead of that harsh power spike that can trip breakers or overload generators, the soft start gradually ramps up the compressor's motor, making it easier to start an AC unit on limited power sources (like small generators, shore power, or inverters).
Not only will this device reduce your startup power demand by up to 70 percent, it's going to make your AC startup quieter, and reduce wear on the compressor. Plus, you get to skip the complicated install and fumbling with hardwiring a unit in. Just plug SoftStartUp between your RV and the power source, and you're ready to run your air conditioner in less than a minute.
You don't need to plan your trips around full hookups or high-power campsites anymore. This soft start device works with 30-amp and 50-amp service, paralleled generators, and even lets you run your AC from a 2,200-watt generator or a standard house outlet. It's weatherproof and made for life on the road, so you can beat the heat wherever you park.
No one wants to choose between using the air conditioner and making breakfast, drying hair, or watching TV. If your AC startup dims the lights or interrupts your Wi-Fi, this device fixes that so you can keep your favorite comforts running together without tripping breakers when the AC kicks on.
When summer heat hits hard, two air conditioners make all the difference. SoftStartUp gives your 50-amp RV the power to run two 15K or 13.5K BTU AC units at the same time on a 50-amp shore power hookup or 3,000-watt generator, as long as your setup matches the compatibility chart below. That means fewer hot nights and less worry about overloading the system.
| Power Source Type | Number of AC Units That Can Start and Run |
|---|---|
| 50-Amp or 30-Amp Power | 2 |
| 3,000-Watt Generator | 2 |
| 3,000-Watt Inverter | 2 |
| 2,200-Watt Generator | 1 |
| 2,000-Watt Inverter | 1 |
