Review on ✨ HQRP 500f 2.8V Super Capacitor: Ideal for Power Source, Boost Packs, Solar Light Projects, DIY & Welding Machine by Mike Rice

Revainrating 5 out of 5

Powerful with low self-discharge

These capacitors are really quite thick. I use 2 in parallel for spot welding. Of the two supercapacitor suppliers I bought from, these were much better, have low self discharge and can make good medium gauge spot welds.

Pros
  • This is amazing
Cons
  • High price
