Description of ๐Ÿ”Œ DROK Digital Multimeter DC Power Monitor, 6.5-100V 20A Voltage Amperage Power Energy Meter with Built-in Shunt, LCD Digital Display Volt Amp Tester Gauge

The portable multi-meter has a Large-screen LCD, can display voltage, current, power, energy at the same time, bright and easy to read. Voltage test range: DC 6.5 100V; Current test range: 0 20A; Power test range: 0 2KW; Energy test range: 0 9999kWh. Multifunctional: the accumulated energy can be reset by button; Store data when power off; Voltage alarm function (over voltage alarm threshold, backlight and voltage will flash to alarm). Easy to hook up: with built-in shunt, 2 wires in (DC + and -) and 2 wires out (The Load), all connections are via a 4 point terminal strip(has a wiring diagram on its back). The blue backlight can be turned on/off by the front accessible recessed switch located on the right side bezel.

Useful but faulty device

I was excited to be able to control the AMPS and WATTS that feed my boat's battery system from my solar array. This counter does just that, but there are a few caveats. First, the schematic is too simple for an installation that includes a solar panel, charge controller, battery pack, and power distribution system. It took me several attempts to get more than just VOLTS out of the meter. And then, after everything finally works, the screen turns out to be quite difficult to read unless youโ€ฆ

Pros
  • Everything is fine!
Cons
  • Fits

Surprisingly accurate and helpful.

These things are bee knees. I have modified all my chargers on several diesel generators to charge through them. These are backup generators and starting on the first try is crucial. It used to be difficult to say exactly how good batteries were without stress testing or hydrometer readings. Those things are still important, but now we can see at a glance how the battery is performing and most importantly, how many watt-hours it's been using. If the voltage is low (on a constant voltage/limited

Pros
  • Great for outdoor activities
Cons
  • Good but not great

Efficient little multimeter.

This little multimeter is really easy to use and very effective. I use it in my truck's electrical system to monitor battery status while the electric cooler is running. It is equivalent to a voltage regulator that cuts off power to the cooler when the battery voltage gets too low. This multimeter gives me a warning before the regulator does its job. Good to know when you arrive at that point so I can start the truck to charge the battery or turn off the cooler until we are ready to continue to

Pros
  • Permanent Test Results
Cons
  • Doubt

Backlit meter and easy to read in any light

I have a 3 digit voltmeter that I use to monitor the 12 volt battery in my car. This is useful, but it could be 12.69 or 12.61, still accurate to three digits. In addition, this is not entirely correct. So I was looking for four digit accuracy in a voltmeter. The DROK counter is the solution I chose. This is a nice backlit display with an internal 20 amp shunt. Currently I'm only using the voltmeter function, so I can't comment on other functions. The voltmeter is accurate to within 0.05 voltsโ€ฆ

Pros
  • Easy to use
Cons
  • Requires an outlet

and I like that it keeps the accumulated Wh readings even when .

I ordered this multimeter to hook up to a bike alternator so I can monitor the output when I press the pedal. Another reviewer wrote that it could be used to measure the power output of solar panels by connecting the panel to the input wires and the battery to the load terminals, and I did that too. The meter is really simple and I like that it stores the accumulated Wh readings even when it's not plugged in. I have not attempted to measure the accuracy of the readings, but they appear to beโ€ฆ

Pros
  • Great overall performance
Cons
  • Hard to say

Great value for money in this great value counter.

The meter works as advertised and for the price it is excellent value. Note that the ammeter is on the negative side between DC IN- and Load-. This is important if, like me, you're using a switch to reverse the polarity of the meter between charging and discharging the battery. The electricity meter does not work in reverse. In other words, the count only increases when positive current flows in the direction of DC IN+ to Load+. The current flows in the other direction, but the power andโ€ฆ

Pros
  • Easy to install
Cons
  • General

Great product -- will probably buy more

UPDATE: After observing the solar panel for about a month I decided to update my wiring to use the output side of my charge controller and not the line from the solar panel to steer . When I went to remove this from the circuit I was surprised to see that the stored energy field read 238Wh when it last read 1058Wh. It had to stay in the 4-digit Wh range or switch to kWh displays at most. There was no way my 15-watt panel could generate the roughly 9,998 kWh needed to rotate the display. Mineโ€ฆ

Pros
  • Price
