Smart dual battery isolator with meter
The POWO by Carlife dual battery isolator with digital display is easy to Install and works great. The display is a little hard to see in bright light, but that is the nature of LED technology. The unit is installed in the back of my truck and connects the two batteries that power my winch, which has no connection to the truck's electrical system. The batteries are connected through the isolator to a battery charger powered by either a generator or the trucks 120v outlet in the bed. The system works great for light use, and will hopefully never get tested under heavy. (which would mean I am stuck up to my doors)

Great product and works as expected.
You will read reviews that it doesn’t shut off at exactly 12.8v, but it’s usually anything between 12.4v and 12.8v, which is enough to get your vehicle started. I have a spare battery in the back of my jeep and this is mounted just above it. I run a diesel heater off my spare battery, so when the spare gets depleted, it does in fact prevent the main battery from being affected. Overall a nice safeguard if you have a similar situation and need to ensure your vehicle can start after using devices for a prolonged period of time.

Stopped working two days after return window closed
Stopped working just outside of return period but they offered full refund so I changed review from 1 star to 5 stars due to their excellent customer service

Perfect way to keep the aux battery fully charged and protected
By far the best solution to keep my generator start battery fully charged and ready to use. I could have added a third charger, but the proximity to engine start battery made this simple to connect and enable charging and isolation at the same time. Voltage display is a nice bonus. Build quality: I like the ability to manually control the isolator, as well as automatic switching.

works good easy to install
Put an electric jack on my horse trailer.....needed a battery to run it and this little gadget to keep it charged without running down my primary truck battery. Took a Saturday to install everything cause I take my time.the photo doesn't show the battery box cause I was still waiting for it to be delivered. Everything except the wood was ordered on Amazon
