Charge guard-Select

Definitely a must have for your upfitting needs to keep your electronics safe.

I bought these to control power to a siren amplifier and a mobile radio. I had problems with my truck battery dying from leaving constant power to them. I set these to come on when it senses power and to go off 5 seconds after it loses power. They work great and I don’t have to worry about turning stuff off or coming out to a dead battery.

Works great

This is a fine gadget - good for protecting your car battery while allowing accessories to be powered directly from it. It is easy to use and set up, and once installed, just works. I designed something like this professionally as an engineer - for use in a battery backed up product we manufactured, so when I say this is well done, I say that with some expertise. I had also used a previous version of this in other vehicles for about 20 years, and it did the job.I would prefer one addition - contacts to allow the over-ride switch to be closed remotely.But, this is really a fine product.

product is fine the new process to get in to amazon will destroy the experience

Use it to power the ECM on a firestone air bag suspension system in my truck when the engine is running and kill power after I shut the truck down (I set it to DC mode). Works well for that purpose. Takes a minute to fire off, and about 30 seconds to turn off in my application. I'm sure using ignition sense would make it more responsive, but there's times when I need the ignition on and don't want the extra amps to draw from the battery from the air bag suspension compressor.

Saved the life of my battery

This will be my second charge guard for my other vehicle. Terrific product and even better company. Great customer service!!
