Have these connected to OFC 0 gauge wire running nearly 10K watts they handle it perfect!
It’s been months since I bought these and I run one coming off my main battery and then another on my auxiliary battery. I’ve got a huge alternator and running nearly 10K on my set up before I even started to think about what Speakers size or anything like that I made sure that the power and wiring is gonna be top notch. I see almost no voltage drops have not had a problem with these whatsoever.

Good quality, good price.
Review of RECOIL ZAFH2-200 2 Pack in-line ANL Fuse-Holders I recently purchased the RECOIL ZAFH2-200 2 Pack in-line ANL Fuse-Holders, and I must say, I am thoroughly impressed with the quality and performance for such an affordable price. At just $12 for two holders, it’s hard to argue against their value. First off, the build quality is commendable. The materials used feel robust and sturdy, which gives me confidence that they will withstand the demands of my automotive and audio setup. The versatility of being able to accommodate 0, 2, and 4 gauge inputs and outputs, enhanced with reducers, makes these fuse holders suitable for a variety of installations. Installation was straightforward, and the holders fit snugly with no issues. The included 200A ANL fuses are a definite bonus, offering adequate protection for my system. Knowing that I have two holders on hand allows me to set up multiple devices or systems without needing to rush back to the store for more. What impressed me most, however, is the performance. I’ve tested these fuse holders with a range of power demands, and they have held up beautifully, showing no signs of overheating or performance loss. The current flow remains consistent, and I appreciate the peace of mind that comes with reliable fuse protection. After positive experiences with my first purchase, I’ve already taken the liberty to buy more of these holders. I highly recommend the RECOIL ZAFH2-200 for anyone looking for budget-friendly yet reliable fuse-holding solutions. They offer excellent value for money, and you can’t beat the convenience of having a dual pack. Overall, if you’re in the market for ANL fuse holders, give these a try—you won’t be disappointed!

Good bang for your buck, great quality.
Works great. Most of it is metal and works as a heat sink. Came with two fuses and the adapters for smaller or larger Guage wires. Fit very well and easily for our choice of installation and was a great price.
