1h 50min charging time for Galaxy S9

Samsung Galaxy S9 does not charge quickly. Standard charging 1 hour 50 minutes is 20 minutes longer than fast charging. They work, are easy to read and the voltmeter is fairly accurate. Mounted on a zero turn mower so my boys can charge devices while mowing. A voltmeter will come in handy. Informs operator of battery level when using 12V accessory 3 stars because it's not true fast charging but still better than many charging options.

Pros
  • Few competitors
Cons
  • There are problems
