The white LEDs are nice and bright
I got the white LED so that I could put it on a pole outside my solar battery bank. Measured it against a standard VOM, and was within .05 bolts of the VOM. Excellent results. Now I can check on my battery levels at night to see if I need to switch back to the utility or I need to go crank the generator. Some complain about the small wires. They are 22 gauge wires which are now industry standard for most all of your instrumentation wiring. It works excellent. Voltage is very accurate. I bought two , one is a backup.

Low price, not waterproof, works good
So far its GREAT. I did tape around the clam shell joint and silicone it, along with the hole for the wires. Just trying to prevent water getting inside. I also used a sharpie to color over the lettering on the outside of it. I wanted it all black.

Simple – Accurate – Durable
Great little voltmeter. I purchased these in a 2 pack. Nice large bright green display with 1-digit accuracy. I mounted one of these on my motorcycle to monitor my stator charging voltage. I am able to easily see the readout even on a bright sunny day. Hookup is simple there is just a positive and negative wire to connect. The display takes about a second or two to initialize. The displayed voltage is accurate, I verified and compared it with a quality DMM. Housing is a nice solid plastic. I mounted the meter with 3m tape and it holds securely. These voltmeters could literally be used to monitor voltage for any 6V or 12V system. The attached wires seem to be around 20 gauge or so and are about 36″ long. Great little voltmeter.

For Information Only!
Accuracy is fair, measuring about -0.016%.Current drain is about 30 milliamps; too much to leave ‘ON’ for weeks at a time when using ‘stand-alone’ to verify a car battery’s charge state. In other words it will discharge your car battery, in a few weeks.The numerals are not evenly illuminated and are a bit unappealing.The ‘Yellow Light’ version matches BMW’s ‘Amber’ quite well.The power wire has no strain relief and obviously not waterproof.Nevertheless this product is VERY GOOD, especially since the cost is super low.

Good and simple
Works well for my use. I am setting up in house 12 VDC system to run various systems especially for power outages. Nice to just glance and see what battery status is.
Works good 👍 –
Pretty good for what I use them for
Been using these for 2 years.And they still work just like brand new. I use them in my solar panel battery box.Pretty accurate.

Not suitable for continously monitoring a battery in long term storage. Priced right.
My Requirements: Continuous monitoring of Lithium 12.8 volt 100Ah batteries in long term storage with no float charger.PRO: It’s very bright and easily readable in daylight (Red model). All 4 read the same voltage when connected to a same voltage sourceCON: 3 digits displayed (not a 3 1/2 digit ). It Doesn’t round up if the voltage is 90mv higher than display) All read the correct voltage measured with a calibrated Fluke DVM to 100mv. Draws ~ 31ma at 13.6v (0.42watts). No means to calibrateNot really waterproof but OK for my needs. Wish it had a on/off switch

Bright and easy to install. Variety of colors
I love these things and add them to many DC machines, vintage cars, rvs, boats, solar applications. They’re easy to read and can be stuck anywhere with a little velcro.

Sottili e molto luminosi sono anche facili da installare grazie al biadesivo già presente.La misura è precisa compatibilmente che è disponibile una sola cifra decimale.

Used these on my power supply and not very accurate at all ended up getting some different ones from another supplier
