Review on High-Speed Motorcycle USB Charger Kit - MOTOPOWER MP0609A: SAE to USB Adapter for Charging Phone & GPS On-The-Go by Alton Walton

Great quality, easy to install, wires are nice and thick with sheathing that appears solid. The only thing I don't really like are the crimp connectors that connect to the battery. They are super soft and thin. They are useless. If you plan to connect it directly to the battery I would change the connections. If you plug it in directly, make sure you disable it. The battery is empty after a few days without driving. Which brings me to my other issue: the connector used to unplug the connector is very tight, which is good for waterproofing, but depending on where you install it, it can be difficult to unplug. Love the fact that you can use the battery connector, but would have liked to see a toggle switch to turn off the power instead of turning it off. Unless you're using it for a battery tender, I'd recommend hooking it up to a taillight or something else that turns on by the key. None of the above issues bother me, but keep this in mind if you're looking for a plug and play thing. All in all, this is a great quality product at a great price.
