    This is one of the best meters i have! I have seen video review of this on Youtube and decided to get it. It is very good power meter and some of them exclusive to this device. I have it monitor my battery of my UPS and for this is perfect.

    Easy, just solder the wires and you are ready to go. I am using it as a energy meter for my ebikes with 36v and 48v batteries. It works ok with those voltages. There is also a useful auxiliary power input for a small extra battery, to be used if you want to keep the recorded values when the main... Read more

    Pro: Funciona perfecto y es muy barato en función de sus prestaciones. Pantalla iluminada. Contra: No se puede seleccionar un determinado parámetro, va cambiando automática y rápidamente. Cuando cesa la alimentación se pierde la información. No es muy sensible a muy bajas intensidades.

    Clear, easy to read, backlit display cycles through a series of measurements. I added Anderson powerpole connectors to make it easy to connect to my Ham Radio equipment. Works perfectly to monitor the drain on my battery pack so I don't over discharge it.

    I've been using this watt-meter on my electric bike for more than 1 year. I've not had any problems with it so far. I'd recommend it to everyone The only con for me is switching values in animation mode. I'd like to have a button to see only Wh, I don't need other max and min values I'd buy more,... Read more
