Review: Enough juice for Tx on a Baofeng UV-5R radio - It is working great powering a Baofeg UV-5R radio from a 12 Volt power source. This allows me to have the radio permanently powered without worrying of the traditional lithium battery that requires constant recharge. It has enough power to supply current for transmit mode.
Review: Great product,small so can be mounted near or on your motorcycle battery - Wired it to use with my heated motorcycle jacket seems to work fine.Wired directly to my battery with on/off switch and a 7.5amp fuse. Product is good to use with limited space near or on your battery

### ⭐⭐⭐⭐⭐ WORKS GREAT!
*by V***C on April 28, 2025*

I use this reducer on my 2000 ZX 6R Kawasaki to make the CDI box function property with my cheap Chinese aftermarket ignition. It is a great inexpensive way to replace the overpriced factory OEM ignition. I even tested it with a very sensitive voltmeter and it is exactly on point as advertise 7.4.
