> 3 dayUpdated to junk now, as one of the two usbs is not working as well as the voltage quit working months ago. Charging via USB works great, the display to show battery/alternator ska display stopped working which I used for an older car. Now useless in the car

> 3 dayI use them in my boat to compare voltage in individual batteries. Also great in the motorcycle for volt meter. Its not just a charge port, its a great tool.

> 3 dayI have a similar device from another manufacturer and thought it would be great to replace it with one that can tell me the voltage. That way when I am playing the stereo with the the motor off, I can keep an eye on the voltage. I bought this device for that purpose. The problem however is when I plug it in, it pops out of the socket. This would not be such a problem if it stayed powered on. Instead any slight movement and this unit would turn off. Of course a wiggle here and there powers it back on. I have tried cleaning the contacts of the socket. Also, I do not have this problem with the unit that was plugged in there before. I would not recommend it.

> 3 dayWe 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.
