I bought these inline fused holders for my Suzuki DR650 motorcycle. When I run my battery maintainer it pops the main fuse. I'm putting this inline between battery and main fuse to use like a switch. I have the inline fuse just behind the right side plastic cover next to the plug-in for my maintainer. Now when I can't ride for any length of time I just pull the blade fuse and plug in the bike. Makes battery last around 4 times longer. Good solid inline fuse holder, and with two of them I have a spare for something else.

5.0 out of 5 stars Just what I needed
Reviewed in the United States on January 27, 2023
Verified Purchase
Got these to upgrade the power cable to my Stryker 655 10 meter radio. Found some 3 pin plugs that could be separated by removing the screws and soldered new pins on the wires now I have #10 wire all the way from radio to my 25 amp power supply. I also doubled up the 2 positive pins and ran another separate #10 ground wire. It took some doing to modify the plug but it came out nicely and works great. Set my power supply to 14.3 volts and now there's absolutely no power drop when I key up and modulate. I did however change the 40 amp fuse to a 15 amp as the 40 amp fuse was just a bit too excessive for a radio that only does about 60 watts. And no, I didn't need a 100 watt radio, in fact I actually turned it down to about 40 watts because I don't need to overdrive my amplifier to get the full power out of it. It does just fine. I highly recommend these fuse holders, the fuses fit tight, the wire is actually 10 awg and the covers are completely waterproof (I tested them in a glass of water overnight)

5.0 out of 5 stars Durable Fuse
Reviewed in the United States on August 21, 2023
Verified Purchase
This is a durable & powerful fuse. We had an aftermarket alarm & power window installation the person who had installed the alarm only installed the fuse without a cover which made the system drain battery. This made things a lot faster since the wire is better gauge & not having to worry the fuse is left naked.
