Review on Ampper Negative Indicator Sticker Vehicle by Adam Madden

I've never had to buy these so I can't compare them to a well known brand but they have everything I need. I actually bought a second unit for my 24v battery on my boat. I also checked them - any and no errors, even with two. You have to watch the load, personally I wouldn't use more than 60 amps total across all your connected devices. Anything beyond that, I'd say get a heavier block. But when it comes to LED lights, phone chargers, and other small electronics, this is a great little fuse box. I would definitely buy it again - oh wait I did. 😀 I recommend it to everyone!
