The XS Power SuperBANK is perfect for high-power car audio systems, engine starting systems, and more. Connect in parallel with any lithium or AGM battery to make a customized power pack, delivering the perfect amount of energy on demand so your amps, battery, or engine gets every bit of power they need—whenever they need it. 

The SB500 delivers a surge of power to the factory 12-volt battery as it cranks, then rapidly recharges (usually in only a few seconds), ready to use again. The improved and  stabilized voltage leads to longer-lasting factory batteries, starters, relays, and engine control modules, improving reliability and lowering the likelihood of costly repairs.

Ultracaps (aka Supercapacitors) also work extraordinarily well in extreme hot or cold. In winter, the Ultracap delivers a much-needed burst of energy to vehicles using a typically slow-cranking AGM battery. Rated to more than a million cycles, the Ultracap is designed to work well in commercial vehicles or “daily drivers”, normally lasting more than a decade.

See specifications below.

Worth the expensive price tag!
Color: Brown, Style: Wallet With Airtag Pocket
Was skeptical at first thinking it will be like other same products and will under deliver, costly but worth the spend. Leather looks premium, no loose buttons and can easily hold 15 cards along with some money clips. Totally sold on this product. If you want quality product and don’t care about the price just get this one. Magnet is also strong inspite of filling it to the brim

Easy on older hands and not too tight!
Color: Navy Blue, Style: Standard Wallet
MUCH better than my first minimalist wallet purchase. Though this one is a little bigger than the last (but still far smaller than a bill fold), it is FAR easier to maneuver. I really like the separate pockets for a few extra cards I use much more often. It took a couple weeks to break it in so cards now move easier than day one and now it's perfect. The money "clip" is also a better feature than the elastic band money clips that some other wallets have, which stretch and get too loose over time. This wallet is far easier for older hands. My last wallet forced me to line up every card perfectly in order to push them back into the spring compartment and bound them so tightly that I could barely get them apart enough to pull the card I needed. This one is far less finicky and less demanding of perfection, making it far easier to push a pack of cards back inside. The thumb pull is really easy to work and the wallet holds everything very securely, yet easy to get around in. It's comfortable, very durable, nice looking and the craftsmanship is superior.

Great wallet with tons of pockets!
Color: Carbon Fiber Black, Style: Wallet With Airtag Pocket
After losing my wallet and finding it right in n front of my face after hours of looking for it I got this one and it’s very stylish with more pockets than i ever needed. The air tag makes it look even better but the fact that i can find it when I’ve misplaced it is very reassuring!

Great wallet.
The card spots work great and the money clip part actually works. I was skeptical at first but the wallet is quite helpful in organizing my cards and money. The material is quite nice and it does seem quite durable.
