How does it work: When the vehicle's engine is running, the alternator will charge the Start Battery. Once the Start Battery has reached 13.20V the isolator will wait 15 seconds then connect the Start and Auxiliary Batteries enabling them to charge simultaneously. When the vehicle's engine is not running, the alternator is no longer charging so the Start Battery voltage will drop. Once the Start Battery voltage is below 12.8V after 15 seconds the VSR will disconnect the Start Battery from the Auxiliary Battery. This means the Auxiliary Battery can NOT drain the Start Battery.

Installing the VSR 1: Connect the (+) positive wire from the Start Battery to the terminal on the VSR marked Main. 2. Connect the (+) positive wire going to the Auxiliary Battery's positive terminal to the other terminal on the VSR. 3. Connect the thin black earth wire to either the vehicle chassis or the Start Battery's negative terminal. 4. Secure the VSR in place.

Important: It is recommended that a 50 Amp fuse is installed between the Starter Battery and the VSR. The negative wire will run from the Starter Battery terminal through to the Auxiliary Battery either directly or via the vehicle chassis. There is a delay built into the VSR which means it can take up to 15 seconds for the VSR to connect or disconnect. The VSR has a light built in which will illuminate when the VSR is engaged (both batteries are connected). If the VSR does not disconnect when you switch the vehicle engine off try turning your high beam lights on for a few minutes

bury me in snuggle sac!!
soo i’ve purchased 6 of the fuzzy blankets, 2 packs of the socks, the cardigan, and now this gem of a cooling blanket! im usually a heavy fluffy blanket person, regardless of season or temperature, but living in florida it’s sometimes a struggle. figured i’d give this one a try since i’m obsessed with snuggle sac. the blanket is very thin, intentionally, and is such a deliciously soft and unique material! the one side is cooling and really cold to the touch! both sides look very rich and high quality. definitely makes a difference so i’m not waking up hot anymore! in order to replicate my heavy blanket habit, i use the snuggle sac ribbed blanket on top of it, and can always remove it in the night. so happy with my purchase! always keeping my eye out for new releases from them.

Cools quite well, about 85% but works well for hot flashes
Being in perimenopause I tend to have hot flashes at the most inopportune times, especially in the middle of winter where I'm sleeping practically naked and everyone in the house is sleeping with hoodies and sweats and extra blankets. I just found out that one side is extremely cooler than the other and the first night I had it I washed it gently dried it in a very light, delicate setting on my dryer. In fact, I didn't let it dry all the way and let it hang up and the first three nights I slept with this blanket. I slept an entire 8 hours instead of the usual three because hot flashes like to do that to you. Wake you up at 2:00 in the morning or 5:00 in the morning when you have to get up for work in an hour. It's very light. It smells great. It's very soft and one side like I said is cooler than the other and you will feel so much better wearing this or sleeping with this rather. I'm

Keeps me cooler than before!!
Color: Light Gray, Size: Full / Queen (90"x90")
I have been going back and forth about buying the Rest comforter but it is so expensive and then I stumbled across this. I am very pleased, it is light and one side usually stays cool to the touch. It does warm up with body heat but usually I let it sit in front of the fan for few minutes and it’s cold again. It was made a huge difference and it good quality for what you pay.
