LIHAN Dual USB Car Charger, LED Display Voltage and Current for Apple iPhone, iPad, Samsung Galaxy /S Series&Edge Models, LG, Google Nexus, Other iOS and Android Devices, Black

This little 12/24 volt adapter with 2 USB ports is well worth the money. If you're like me, your car has no voltmeter so you're only aware of battery or alternator trouble when you see a warning light on the dash... which by then is too late. This handy device will not only charge up to two devices, but will show you how many amps are being pulled from the battery while doing so. And when nothing is charging it displays how many volts your battery is currently operating at. And because of its short plug length, it doesn't stick out of your outlet like a lot of dual or triple USB adapters. In fact, it only ends up protruding one quarter of an inch from my dash. (Your results may vary depending on your car's interior design.)No matter how well it fits, for $10, its a steal for two USB ports, a voltmeter, and an ammeter all wrapped in a simple, sleek, shiny black adapter with a handy little digital display. Far more than you get with most of your basic 12/24v USB adapters.

Worked great, and liked being able to see the voltage reading. However, the metal pieces on the side would get pushed up into the charger when I plugged it in sometimes. Now it's totally broken and having to buy a new one after less than a year of using it.

Smaller than expected but after getting the equipment setup it fit perfectly. Numbers are decent, so no distractions at night. Seems to charge well.

Works as expected

Mostly works but be aware of what the voltage in the amperage requirements are of your devices. My device is needed more amps and they did not publish the exact voltage and amp outputs on each Port and so there was a mismatch and so my devices reboot not a fault of the charging device itself. Just more of the product description should be more explicit in what the outputs are per port
