There you are - waiting for help to arrive. Your truck wouldn't start and you had to call the tow company to come out to give you a jump. And it's raining. And there's no doubt you're likely to be charged slightly more than a hefty sum for a simple one-time service. Do yourself a favor and get the JumPack H20. Here's why.

The JumPack XL H20 gives you powerful, portable jump starting convenience for your car or light duty truck, so you can rely solely on yourself for help and stay in charge of your own schedule. It's totally simple and loaded with built-in protections. It's even water-resistant when all the ports are covered. Use it, recharge it, use it again - over and over. Rain or shine, go big and get home with the JumPack XL H20.

Also, if for some bizarre reason you're not going to get one for yourself, how good would this thing be as a gift? It's perfect and you know it. And since you're getting one to give as a gift, just add two to your cart and get one for yourself, too. Imagine you don't and then later on you're sitting in your stranded car waiting for the tow truck to deliver a jump - and your bill. Ouch. That one's gonna sting.

So, What's a Trickle Charge? Is It, Like, The Bill For A Leaky Faucet?

It's not. It's actually a way of sending a charge to a low vehicle battery from inside the cabin through the 12V accessory port. So, if it's cold outside and you don't want to stand in the raging wind hooking up the JumPack directly to the battery, you can connect it to the 12V accessory port and let it slowly send power to the battery so the car will start on its own later. It's not as quick as a jump start but it has its advantages.
