And that's just the immediately visible problems. In some product categories it's difficult to find a single product where the description doesn't outright lie about features or quality, and the only way to tell is the price.
Louis Rossmann recently tested some of the highest-rated fuses sold on Amazon. It took over 8A to blow a 2A fuse.
By now I only order there if I can't find a more local alternative, the only remaining area where Amazon is still ahead (or rather, not behind) are delivery times.
- nick__m 3y agothose are great fuse they don't blow up like the one they replaced! 5 stars, would burn again
- lebean 3y agoWow, 8A to blow a 2A fuse? That's 4x the value!
- lb1lf 3y agoThere's a lot of 'That depends...' when it comes to fuse ratings; for instance, a tardy porcelain fuse of the kind used domestically in Scandinavian countries until fairly recently were rated to take 90% over rated load for 1hr before melting; they were basically only going to provide short circuit protection. Depending on the category of fuse and the time it held at a lower current before ramping it up to 400%, it may have operated as intended. (Squinting at the C type trip diagram in my fuse box, it appears the fuse will withstand 2x rated load for 6 seconds before tripping, 4x for 1.5 seconds or so.)
