PA012 Dual Port USB Power Adapter and Voltmeter
Glad I found this at a local store. The eBay type I'd purchased previously was sloppy, kept coming loose and cutting out. I've been running this for approx 2 months and its held up well on my Tiger 900
This unit exceeds the specifications quoted. I tested mine on arrival with my bench power supply and USB loads. You definitely can simultaneously draw 2.1A from each port. I tested the unit from 8V through to 14.2V and it tested OK, even when starting your bike the unit should keep working uninterrupted. The bonus voltmeter was one decimal place out at higher voltages and spot on at lower ones. Definitely recommended.
Used in the cockpit of my Multistrada to charge my phone. In the few days I've owned this adapter, it has worked just fine. The voltmeter is a bonus.
