Review: Awesome! - Awesome little gadget! Use to monitor my battery on my atv and run phone charger, gps ect! Works perfectly, easy set up and has been durable! Actually have bought another one since writing this!!! Review: Inexpensive, fits handlebars, works well - I ordered this and a coolant temperature probe at the same time, and installed them in a few hours of work on my 1996 Honda Shadow motorcycle, which came with no instrumentation other than a speedometer and odometer (and a reset-able tripmeter). This device does three things: 1- constantly shows you the volts at the battery, 2--provides you two USB-type A charging ports for phones or GPS navigation devices, and 3-- constantly provides you the current outside air temperature at the handlebar. THE GOOD: The device is inexpensive, and for purposes #1 and #2 above, works great. I've used it for 2 weeks now, and about 800 miles of riding. It was pretty simple to install and wire-up, although that's a pretty big deal on my bike because you have to remove the seat, the gas tank, and both side cover panels, and undo at least the positive side of the battery connection / terminal. Since I was wiring two devices, this was a bit more involved. PS: My bike has had, for more than a year, a permanently-wired SAE "Pigtail" through which I can connect a smart battery trickle-charger. Battery tender, it's often called. That quick-disconnect connection isn't wired through the ignition key switch, so it is always available to charge the battery on a bike that's parked with the key out. I ultimately decided to buy another SAE Pigtail, a 6" long wired piece, to use to power these new gauges. So when the bike's being used, I plug in these devices. When the bike's parked overnight, I unplug the handle-bar mounted devices (and have the option of plugging-in my battery tender). If I wanted to do more work, I might have wired both of these devices to a switch through which I could "turn them off" without unplugging anything, if I wanted to kill the power to them when parking for a few hours, or parking away from home, but with no intention of using a battery charger in the next few days. THE BAD: This unit's air temperature sensor is fully exposed to the sun, so it reads unusually high during most of the daytime, when riding on roads that are not heavily shaded. It reads too high when parked in the sun. Also will show unusually high temps when parked or idling due to the engine's heat rising up and flowing past the handlebar where this unit is mounted. It is accurate, however, at night when moving or when the bike's been parked overnight and is cool. ## Features - 【3 IN 1 FUNCTION】: Including dual USB charger、thermometer、voltmeter, save more spaces and easier to use - 【VOLTMETER & BUILT-IN FUSE】: Red digital voltmeter as a battery tester for checking the state of your battery and battery charger.

Can you change to Fahrenheit?** A: No. I am slowly trying to learn to convert to Fahrenheit in my head . . . bummer, huh **Q: I read conflicting answers. so, what is the maximum input voltage? dc 36v ok?** A: 12 volts **Q: I recived these unit toogoo 195581 today. I connected to battery 10v and the voltmeter start to blink. Is that ok ? No constant indication?** A: It should be constant, the mount on mine broke after a couple days, also the product picture changed but they used the same listing, Amazon should not allow this as they are selling different products with good ratings for a different unit!! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome! *by M***N on May 21, 2025* Awesome little gadget!
