It's 500 farads, that's fine.

500 farads are okay. My $45,000 LCR meter at work doesn't even read it. rzunimag. Charging takes a long time, I could only put 1 ampere on my small power bank, that's quite a bit of capacity! I will use it as a mini spot welder for attaching rings and welding battery terminals.

Pros
  • Amplifier installation
Cons
  • You could have chosen a newer model

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

  • The best in its niche
Cons
  • So-so

These are not jokes worth their money.

I'm very surprised I didn't believe it. I can't tell if there are 500 ferrets or not simply because I don't know. but I can say I charged a 5 amp capacitor in about 3 minutes, more or less, and I've run this motor for 15 minutes now and it's barely dropped 0.2 volts. I'm not the type to leave good reviews, but in this situation I want other manufacturers like me to know that this is definitely worth a look. Plus if they get more I'll order enough to make a 12 volt cell.

Pros
  • Absolute Legend
Cons
  • Zero
