Greater than one weekWe use this adapter on our sailboat to know where our battery charge is at while at anchor. It saves us turning on our inverter (which seems to use a fair amount of battery power). It also allows us to charge our electronic devices and see how much battery they use. My husband shows this to everyone we know that has a boat. Several have talked about getting one. Wont know until next summer whether they did or not. It is great to not have to worry about when to charge the boat batteries.

> 3 dayI like this plug-in volt-meters simplicity and the ability to charge mobile devices via the USB ports. I bought this version because the amber display matches the other elements on the dashboard of my car. Because the outlets go dead when the vehicle is off, I still have to occasionally check the battery with a meter under the hood.

> 3 dayWorks very well. I am sure it is not 100% accurate but.. it does give a voltage reading on my cars charging system and it charges my phone fast!
