Drink 12 volt to 6 volt step down converter.
I ordered 8 of these to wire individually for my gauges, radio, clock, wiper motor, and heater blower when I converted my 6v positive ground car to 12 v. Perfectly designed, easy to install, compact piece that fits in tight spots, and worked perfectly! Highly recommend!

Happy happy
It’s not a full 9VDC output, but close enough. Works with my QMX+ transceiver wired for 9 volts.

Spot-on Accuracy!
I recently used an emergency radio from CC Crane, the 'CCRadio-SW', while at 10,000' in the Colorado high country, while elk hunting. Unfortunately, the large capacity 'D' batteries ran down, so we were out of luck keeping updated on weather, etc. I wished that I could have connected this radio to a large, marine-type, deep-charge, 12v battery, which was running our lights, but I didn't have the proper adapter. CC Crane tech staff later reported that they used to carry a 12v adapter, but no longer. The tech guy confirmed that I would have to be sure not to fry the circuitry in the radio, and would have to reduce the 12v DC to 9v DC. This converter from DROK is perfect. This component is very well labeled for in/output, and polarity. My digital multi-meter reads an output of a hair over 9v, from a fully charged marine/deep-cycle battery. I connected this DROK converter to an in-line fuse holder, using a 0.5mA glass fuse. My radio is rated at 500 milliamps, so this arrangement is working great. I used 18-22 gauge, crimp/butt connectors, pieces of small gauge wire, and used an old DC plug, being careful to observe correct polarity. So now, this radio will operate off of 120v AC, 12v DC, or 'D' batteries...perfect for an emergency/backcounty radio!

Good step-down transformer
These are excellent step-down transformers. I've got several of them, and they always seem to have the right voltage and amperage for my applications. I've got a couple that are a few years old now, and still working very well. Excellent product, highly recommend.** UPDATE **Had to take away a star on March 18th, 2017; last one I ordered only lasted 14-months, and that was with powering a simple 10w transistor radio (insignificant, constant load). Durability shouldn't even be a consideration on a simple dc/dc power converter, either it should work, or it shouldn't - not 14 months until dead - not when stepping down a constant load that's half the rated load.

Input voltage must be 12 volts
I bought this product to convert a 6v ride on toy to a 20 volt dewalt battery but the 20 volt input voltage was too high to let the converter do its job

Worked well with a 6 volt vintage car light1
I purchased it to test 6 volt accessories from vintage automobiles. This unit had no issues with a combination tail light/reverse light. This is much cheaper than purchasing a 6 volt battery to do the testing. I will be hoping to test this on a 6 volt ahooga horn in the future and will update the review to advise whether it can handle the amperage.
