SAE to USB Adapter, Motorcycle Waterproof Quick Disconnect Plug with Dual USB Charger 2.4A & 2.4A (4.8A) & Voltmeter for Smart Phone Tablet GPS by YonHan - Blue

Does not read voltage accurately. Verified the reading against two different devices (my charger which displays voltage and my multi-meter). It displayed 11.9 V (which oddly enough is the voltage displayed in the pictures of this product) whereas the correct reading is 12.2 V. 2 stars for functional USB charging ports. Returned it nonetheless since the voltage reading was the primary reason I bought it.

Worked with out flaw

Make sure to disconnect when not in use.

Waited several months to review this product to see how it held up. The answer is very good. I needed an USB port to charge my phone while on the motorcycle and this was easy to install and has worked quite well. I strung the wires under my gas tank and feed the power to the unit by plugging it into my usually used plug that keeps my battery tended. Ie, when on the charger this is disconnected I use that connector to run the USB port adapter. Nice thing is there are two ports if needed for another device. Would recommend.

Easy to use. Easy enough to install depending on your battery location and terminal type.Adaptor however died in only a few short months of very light usage. Haven’t yet taken apart to check for internal solders. Usually with these Chinese made products, the quality is extremely low.One star for the durability of this product.One star for the dual charging port. I usually would use Battery Tender brand but they were either lost or broken by my own fault.

had it for about a week before it stopped working it was vary finicky before it stopped working was disappointed
