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.

Wood & Metal Desk Organizer – Sturdy but Assembly Needed
This desk drawer organizer and pen holder is made from wood and painted metal and looks nice once assembled. The type of wood isn’t specified, but it feels heavy and solid. The pen holder requires assembly, which can be a bit tricky since no instructions are included. You need to attach the two wooden sides to the wooden bottom first, then add the metal sides. The screws are included, along with two mini screwdrivers, but the tools are very small and the wood is very hard, so I needed help to finish assembly. Once assembled, the items look attractive and feel sturdy. My organizer arrived with a small chip in one of the metal pieces, leaving a spot where the black paint is missing, which is noticeable. The organizer works best as shown in the listing photos — for larger items like glasses, wallets, cell phones, or keys. The sides of the organizer aren’t completely flush with the bottom, so very small items like paper clips could get stuck or fall through. To protect desktops, the organizer comes with four stick-on felt pads for the corners, and the pen holder has a rectangular felt pad that you attach yourself. Overall, it’s attractive, sturdy, and useful, but assembly can be a little challenging.

I like the wood and metal look. The pencil cup was easy to put together and it is sturdy. It is great to have some organization on your desk.

Love this protection plan
Quick and easy. My daughter's cracked her screen on her phone, as soon as it happened I went on the app, filed the claim. Ten minutes later I received the email with the shipping lable. The following day I dropped the phone off at ups and 4 hours later I received the digital gift card. Ive filed several claims since getting the protection plan and with four kids its definitelysomething im glad to have especially since i dont have to buy a protectionplan for each item now. I have filed claims for electric scooter the stoped working for no reason, my son's phone stopped charging, my oldest daughter cracked her phone screen, my son's video game controllers up and died and each time it was quick and easy and no fuss
