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.

Neck posture/sleep pain improvement
Item Package Quantity: 2, Size: King
Pleasantly surprised. Only had for a week now, but bought to replace these old bamboo pillows that were so flattened it was causing shoulder pain or neck tightness maybe. But that has already improved my sleep just from using this week. Ordered the kings, they come vacuum sealed and so I opened and they sat for approx 24 hours or close enough. They didn't appear as puffy so I was a little doubtful but I punched and fluffed them myself and they were good. They have improved the quality of my sleep so far. They are soft and sounds weird but it's almost like your head weight or fluffing them activate it to be fully expanded afterwards. I like them, they're comfortable for me as a mainly side sleeper/sometimes back sleeper.
