Great little unit. However, be certain of polarity if hooking up to battery or solar panel.I accidentally use the wrong cable when connecting to my solar panel (had polarity adapter on the cable from another device) one time and it fried the unit. Apparently, No polarity diod on this guy. My fault and I realized it as soon as I did it but now I have a brick.

I bought this to power a high powered wireless charger (a through desk style) for my car. The center console plastic was just a touch too thick to do with a standard wireless charger. The charger I bought specified that it could only run on a QC 3.0 compatible usb, so this seems to be truthful in its claims that it is! Also happy to report that it barely consumes any power at idle ( I used an always powered 12v line) , so even with the wireless charger hooked up, I havent noticed any draw on my battery. Left the car for two weeks and it started right up.

I made sure the polarity is right and hooked it up to my 12v signal on my escooter controller and it shorted, ruining my controller. To make sure I connected it correctly, I hooked it up to a 12v battery and the wires were overheating. Reversing the polarity caused sparks so I really know I connected it right. Other concern is the pigtail is using probe wires commonly used in voltmeters just to detect signal. The insulation is thick yet the wires are so thin, I wouldn’t even trust putting 1a through them, it is a potential fire hazard. Now my scooter is bricked. Lesson learned, always test directly from the power source than to trust the unit will work.

The pic shows the voltage regulator connected to a 12 V battery. The other devices a USB voltmeter.It shows it takes the 12 V battery and outputs 5 V.The voltage regulator accepts 10 to 35 V DC. Second picture shows a 20 V tool battery connected to the voltage regulator then connected to the USB multimeter. It also shows 5 V out.So you can use any type of battery from 10 to 35 V DC into this voltage regulator to get 5 V out.5 V is what charges your phone.5 V Also operates the Blink system security cameras if you get tired of buying lithium AA batteries. I have a couple at the house in the lake that are out away from the house that I would rather use the 12 V seven amp hour battery with.

I am using these on a Haibike eBike with Bosch Performance Motor as well as an eBike with Tong Sheng TSDZ2 motor. For the Bosch system removed the stock lights and wired one to the stock front light wiring and one to the stock rear light wiring. On the TSDZ2 I used a wiring harness that splits power on the speed sensor circuit and wired it directly there on the 6v pos/neg. I have been using Orfos USB powered headlights and tail lights with no issues. The only issue I have is that I can charge my iPhone XS only if it's the only thing plugged into this adapter. Once I plug one of the Orfos lights into the second port I get an error message on the iPhone stating that 'This accessory is not compatible' and it stops charging. If I don't plug anything else into the adapter it continues to charge with no errors. I may try to splice a second adapter into the front light wiring and see if I can get the iPhone to charge on one adapter while still being able power a light on a second adapter on the same circuit. The error may be because the amps drop when I plug in the lights in which case adding a second adapter to the same pos/neg will not work since it's drawing power from the same circuit.Overall I am happy with it and I no longer need to use USB power banks to power my USB powered Orfos lights.
