RECOIL R1D 1.0 Farad Car Audio Energy Storage Reinforcement Capacitor with Blue Digital Read-Out

Charged super fast, install was pretty easy. Only down side is the terminals for the wire hook ups is a tad big. Have no more issues with lights dimming when sub hits hard. Would buy again.

As I suspected, my little 4-banger's alternator just wasn't providing enough juice to power my 1200w amplifier. It was impacting my vehicle's performance as well as my subwoofers. Not any more! l can still see a tiny flicker in the headlights when it hits hard, so I assume this is best suited for systems 1000w or less, but I'm not going to complain because it's a vast improvement. Side note, I thought the terminals had nuts, not bolts, so when I unscrewed it completely after the initial charge it got hung up and I dropped it. They are just long enough to connect the positive and negative terminals, FYI. After hearing "zzzzzzPOP!", I thought for sure I had fried it but I hooked it back up and it charged up just fine.

I have a nice sub amp in my UTV that has a fairly small battery and the amp would go into protect mode as the voltage sagged during almost every song. This 100% did the trick, the sub stays powered up and thumping at all times:)

Was looking to find a capacitor for my car audio system install and chose this because the reviews were good, it was affordable, and looked nice.My system is a 500W monoblock amp pushing a 12in subwoofer.It was straight forward to installSeems like a good quality capacitor as far as the build goesIt doesn’t store enough power to keep my lights from dimming when at idle.You get what you pay for, may as well spend more and get something better.Edit: Seller reached out to me to try and help rectify the problem and they gave me a refund as well as suggested a higher farad cap which I’m going to try. Great customer service!Raising my stars up to 4 for now until I receive the new unit to test.

So far seems to be a good product. Didn't have instructions. Couldn't go to website. But figured out how to charge. Works Great.

I read the other reviews and many said that this cap was about 0.4f instead of 1.0f. Well I have to agree, I measured the time constant on discharge and came up with about 0.4f. So I think their advertising department was looking at the specs with rose colored glasses. For my system that's probably good enough, I'm running a 600w system with a 1000w plug into the wall power supply. The 1000w supply is a switcher so it has pretty small output capacitors compared to a regular heavy 60 cycle supply. I don't know how fast the switcher can respond to a large fast change in load current, especially with a long extension cord, so I figured this capacitor would help.If you need an actual 1.0f or bigger this is not what you want.

The media could not be loaded. I think people just give bad reviews either because they got a bad product which happens. Or they just are trying to get a refund. I experience nothing wrong with this product. Even after I accidentally dropped it twice from my shoulder length to the floor concrete. It’s durable . it’s well worth the money

I'd like to have duel positive and negative posts on this - one for the feed, and one for the amps but alas, this will have to do. I think I will have a 1" firring strip behind each mounting point to allow the power cable to pass behind the capacitor. Time will tell.
