5 of 5 Well thought out design May 19, 2026
Reviewer: Original 1991 Miata Owner from Charlotte, NC United States  
Having never smoked the cigarette lighter in my 1991 Miata has seen little service except for occasional use as power source  for small electronics. What I really appreciate about the USB design is that it already has the correct wiring clips to connect it the original lighter power connector, and a digital  voltage meter. While generally a voltage meter isn't necessary,  its a great thing to have to determine quickly if the battery or alternator is weak or going bad on a trip before you actually get stuck; I've the found replacement batteries these past few years to be pretty unreliable. Personally I won't be installing it in the lighter hole but instead extending the wires to place it in the lockable center storage console between the seats. That's where I normally keep my phone on a trip. As to the cigarette lighter itself. It will just be reinserted disconnected, into its original hole, to retain the original look.

5 of 5 Voltage Display October 19, 2025
Reviewer: Randy Day from Front Royal, VA United States  
Your video on install was spot on. Installation was a breeze. 20 minutes tops. The constant voltage read out gives me comfort for being 35 years old.

5 of 5 Cool replacement for my broken cigarette lighter July 5, 2025
Reviewer: Peter Bulena from Capitola, CA United States  
Easy install, used a step hole drill instead of a dremel/grinder. Red wire blade didn't fit in tight so I crimped it a bit and taped it in. Works as advertised.

5 of 5 Nice Upgrade! June 12, 2025
Reviewer: Marcus from Columbus GA  
I bought the green one and it was shipped very fast and came in a day early. Installation video was very straightforward and clear to understand. Overall it took me about 10 minutes to take out the crappy old cigarette lighter and install the new one. I didn't have a dremel or a power tool so i used a handheld metal file and it worked fine. Nice unit, I like that you can see your battery & alternator voltage. Overall 5 stars!

5 of 5 Great way to add functionality June 27, 2024
Reviewer: Jacob Dougherty from Billings, MT United States  
No complaints, easy install.  Having to make the hole slightly larger with a dremel was a snap, its nice to be able to moniter the alternator and have charging.  Slam dunk product.
