That limits the amount of sulfur in the cells and ensures both the maximum capacity and the longest life." If it sits idle for a month or two, recharge it fully. "After you use it, for a jump or something else, recharge it fully. "When you get it, charge it fully," says Dan Portwood, senior product manager at Baccus Global, a manufacturer of multiple jump-starter brands. But if you want the coolest, most fail-proof portable jump starter out there, this might be it. It's intended primarily for commercial purposes and it's not cheap. It has a small, replaceable lithium ion battery to prime the ultracapacitors, but if the onboard battery is drained it will still prep the ultracapacitors in roughly two minutes on a 12-volt charge from a vehicle (maybe even the weakened battery in the vehicle that needs a jump). The Schumacher Ultracapacitor Hybrid Jump Starter delivers 900 amps of cranking power, which should fire just about anything up to a semi-truck. That makes them perfect for jumping a weak car battery. And they can operate effectively in a broader temperature range than most batteries. Modern ultracapacitors can absorb energy quickly and dump it in big jolts, as opposed to something more like a trickle with a battery. Compared to chemical-based batteries, they store relatively little energy, but the advantages are significant. Once referred to as condensers, capacitors store energy electrostatically in an electric field. It made it because it's really cool, as it applies the next wave in electrical storage technology: ultracapacitors. This one violates the spirit of this list because it's only a jump starter - no LED flashlight, USB charge port or anything else. After all, you want to have enough power to prepare for pretty much any emergency on the road. To be sure, these features add bulk and mass to a jumper pack (these devices won't fit in your glove box), but their value in capability, convenience and preparation can more than surpass the extra weight. Do you need to charge your phone and another USB device (your kid's Nintendo Switch, for example) at the same time? Many of these have a dual USB port to accommodate your charging needs. These power pack devices are basically the ultimate power bank. Would you also like a jump starter or battery charger with an AC inverter so you can plug in a radio, a lamp or another small appliance during a power failure or at a campsite? Done. Want a battery booster with a built-in air compressor so you can fill up your raft at the lake or a low tire before you head home from the airport? No problem. What else can it do? On a single charge, a portable car battery pack or charger can power your high-draw laptop computer several times longer than its own built-in battery.
