⚡ Cllena Waterproof 12V LED Digital Voltmeter for Car, Automobiles, Motorcycle, Truck, Boat, Marine - Blue LED with Terminals Review

Built into the fairing of my motorcycle. Allows me to monitor the battery when the engine is off. Looks clean and well made. See the lower right corner of my bike's fairing to see the installation.

Installs as part of a DIY battery box to power CPAP and USB chargers. Recognized as accurate, easy to assemble (just use the right step drill bit). I considered adding an on/off switch, but the current draw is so low I just left it plugged in.

Cannot read in any light in the sky or in the garage. The front scratches and scratches easily. Although it is clearly visible at night. Reads exactly as tested by my Fluke DMM. Good flush-mounted pressure gauge, a pity that it cannot be seen. would not recommend

Great counter! Nice and compact! Reverse polarity protection (tested) because my circuit requires it! (I designed a foolproof circuit that requires reverse polarity protection). However, I did manage to kill one due to dirty DC coming from a charger commonly sold at auto parts stores. I would definitely buy more of this item!

Received today, both spades stuck through the bubble wrap. Obviously it was packed with some weight on it during shipping to cause this, but the wingtips were not bent and the gauge worked fine. Good clear, light blue numbers. Time will tell if the sensor can withstand vibration and use, but so far I'm happy.

I like the meter and because I bought it before I knew how to connect the wires BUT wouldn't it be so difficult to include a wiring diagram for the first time buyer? Five stars before I installed it. This caused my battery pack to fail. It showed my battery voltage of 4.85 volts when my voltmeter read 12.8 volts. When connected, neither the USB ports nor the 12-volt socket worked. Stay away.
