NOYITO DC to DC 12V-22V to 3.7V 2A 3A Max Power Converter - IP67 Waterproof with Overcurrent Protection (Black)

This allowed me to create a 12 volt lead acid battery converted to 9v to power a DSLR for extended time lapse shoots.

works just fine – not exactly 9.00 volts but close enough The attached photographs are variations in NO LOAD output voltages with various input voltages from 4s to 6s lithium cells. The under load output voltages were much closer to the stated 9 volt DC output voltage ranging 9.3 – 8.9 volts DC. The electronics components I am using do not need a super accurate voltage like the old vacuum tube voltage circuits provided. I always incorporate fast fuses so I don’t have to rely on the claimed “over current” protection. I am staying way below the 3 amp 9 volt = 27 watt rating.

Does what it says and within tolerance for output voltage. Doesn't seem to get too warm.

I used this to turn my shaver from a dc to ac current shaver. Still working just fine. Been using it 6 or 8 months maybe.

Looks legit. Never wound up using.

POS!!!!! Does NOT WORK!!! Had a project on my truck for a while now and once I had time to work on it and finish, the last thing to do was connect this to the 12v power and ———NOTHING!!! This thing is garbage!! DO NOT BUY!!!

Worked great for my application. No complaints

I installed this about 6 weeks ago, and it worked without issues. Unfortunately, yesterday, the output went from 6V to 12V. It will not go back to 6V, which is what it is spec'ed for. The seller reached out to me and offered a refund, which I really appreciate.

I will recommend this product it works well and cheap
