Ensupra DC Electricity Usage Monitor; 150Amp Power Analyzer; Battery Consumption; Performance Monitor ;DC Watt Mater for RC,Battery,Solar,Wind Power; 2 Year Warranty

Worked for the first two days and now very sporadically. Can't figure out what makes it. The light is on, but no information is visible. Had it professionally installed with soldered connections, so to replace it I have to spend double. Transmits power without significant loss, so I have been trying to ignore it, until I find something adequate in a store. This is not an item you want to purchase online.

The wire gauge is 10 AWG, perhaps 11 AWG, neither of which are really appropriate for 150 amps. You get about 2" to 2.5" inches of the cable on each side. My usage will stay below 90 amps so it's not a deal breaker for me. The LED "display" is thin plastic. It shouldn't break or anything, but it may pop off at some point because it's glued on the outside. The rest of the housing is quite durable.I would have liked to see 8 gauge wire so that you can actually use this up to 150AMPs as advertised. I would have also liked to see at least 6 inches of wire for the leads.UPDATE 06/23/2016It does not seem to be very sensitive. I have it between a 9Ah battery and a lighted volt meter. The volt meter detects that it is a load but the usage monitor shows nothing is being used. When I attach my radio battery charger it does detect the load though. See photos

The first monitor did not work out of the box, so Ensupra shipped a new one out right away. The new one is working surprisingly well. I have a solar powered system that I use for backup, and for the past two days, I've had the Ensupra monitor connected between my batteries and the invertor to get a handle on managing my battery bank. After double checking the readings several times with a hand held multi-meter, the data displayed is right on the money.

Excellent meter for my battery power system. Very accurate in giving DC volt, ampere and wattage.

love it, but it is my 2nd one. the 1st one stopped working after a year

Works well, does the job.

Love this thing. Wanted to wait till I had used it for a while to review it. I needed a watt hour meter to tell me the accumulated watts when charging my devices as well as how much power I have used giving me an idea of what I have left in my battery.

Easy to use. Fast, easy analysis of power usage or charging. Satisfied with purchase. Will purchase an additional item.Red and Black wiring from item has stamped on Black wire: 12 AWG 200 Deg C. Clearly, the wiring is 12 Gauge (12 AWG). Final on wire size.
