Description
It is a device used to cut off the power supply of the car to prevent the car from leaking and damaging the battery, or consuming the battery power by not driving for a long time. It can set the voltage value when the voltage is lower than the set value will automatically cut off the car power. Can be mobile phone close to automatically turn on the power, do not need to manually operate. Universal for pickup trucks, cars, vans and most other cars, rated current 500A peak 1200A.The shell uses flame retardant materials, the power cord also uses high temperature silicone wire, the relay uses a motor relay developed specifically for car power cuts, which can be locked after powering up to prevent vibration-induced false connections or power cuts.

Convenient disconnect
Style: 500A mobile control
Have had these on a Jeep JKUR and my 2019 Ram Rebel. My Ram doesn’t like it when the battery is disconnected. The AC and backup camera malfunctions for a bit. After a few hours and turning the truck on and off it does correct itself…eventually. But we sometimes leave for several weeks where this disconnect works great for my needs.

Very Good, Vendor Resolved Issue with mobile app
Style: 500A mobile control
The app I downloaded was not in English. I contacted the vendor and they asked me to wait while they upgraded the app. Plus they issued a partial credit. Other than that, the hardware seems excellent and does work. Although I have to wait til I have used it for a few months to know further. The mobile app could be better but I shopped and shopped and there really isn't anything else to compare. So I do appreciate this product very much. Plus the vendor was fast to respond and very earnest to resolve the issues. Thanks!

It works well
Style: 500A mobile control
This device really helped me in a tight spot. I had a bow thruster battery I needed to install and need a quick fix battery isolator that enables a remote because the battery is buried down deep in the bow. The remote worked for my purpose until I could get to a location to do a more permanent ABYC job done on the boat.

Work perfectly!
Style: 500A mobile control
This is the best battery disconnect switch I have found works great for any vehicle! Low voltage disconnect works perfectly so if you have a battery drain this is the way to go!

why is there random beeping?
Style: 500A mobile control
The 500A switch was easy to install and get control via my cell phone. I have one issue though, I continue to have random beeps from the unit or the car. I ve tried to disconnect the Bluetooth connection because I thought it was my proximity but whether I have the turn on or off with proximity it doesnt change the beeping. I cannot find a direct contact for verbal support but to no avail.

Repeated auto turn on issues.
Style: 500A mobile control
I am experiencing repeated auto turn-on issues. This problem occurs with all versions of the switch with mobile access that I’ve tried. Disabling location access worked for a while, but now the switch automatically reconnects the power whenever my phone’s Bluetooth is in range. This raises the battery voltage above the auto power-off threshold, requiring several hours or days before the Sway function can disconnect it again.

Good Solution for Parasitic Draw, But Ground Connection Could Be Better
Style: 500A mobile control
I never knew products like this existed until recently. I’ve been dealing with an electrical parasitic draw in my vehicle for over a decade, and this seemed like a great solution. Being able to completely disconnect the battery remotely gives me peace of mind and prevents the battery from draining when the vehicle sits. I’m running a 300-amp alternator, dual batteries, and a high-powered sound system with multiple amplifiers, including a 6k watt amp. The remote works as expected, and the range is adequate for my needs. Initial functionality appears solid. The reason for the 4-star rating is the ground connection design. The housing is plastic, which doesn’t provide the most ideal grounding surface. While driving and putting my system under heavy load, I blew fuses,something that hadn’t happened in years. That led me to inspect the ground path more closely, and I ended up trimming a small portion of the plastic housing to ensure a clean, solid ground connection. For high-current applications like mine, proper grounding is critical, and the design could be improved to provide a more direct ground path. For typical vehicle setups, this likely won’t be an issue. I haven’t had enough time to fully evaluate long-term performance yet, but so far this appears to be a very promising solution to a problem I’ve been trying to solve for years. With an improved ground connection design, this would easily be a 5-star product
