Product Description

Schumacher SL1 Lithium Iron Jump Starter is a multi function device to charge cell phones, power a 12v device, and jump start your vehicle in the case of an emergency. Featuring a full featured flashlight with two modes (solid and flash). This compact jump starter is easy to carry and can easily fit in most vehicle's glove boxes. Jump starting is made simple with a convenient quick start guide located on the bottom of every device. Never be stranded because the operating manual is missing.

Included is a USB to microusb adapter, easily charge most USB devices. In addition, a 12v socket adapter is included allowing one to power 12 v devices such as air compressors, mini refrigerators, and reading lamps. Charging the Schumacher SL1 can be charged by the 12v cigarette outlet in your vehicle and by any 120v wall outlet.

The SL1's powerful jump starter can jump start most heavy duty batteries easily and quickly. Use the included high grade connector and clamps to attach to your dead battery. The SL1 will give an immediate readout of the current state of your battery's voltage. Simply press the jump start button and wait for the unit to indicate that the unit is ready for jump start. The vehicle should be immediate be able to crank and the unit will go into a cool down mode to safely prevent the lithium-iron battery from over heating. Trickle charging is possible by just connecting the SL1 to the dead battery for a slow and steady charge if necessary (great for motorcycle batteries).

This unit worked well for three years - jump started 4-5 vehicles during that time. It had not been used in the last 6 months. When I pulled it out to check the level of charge, it had swelled to the point of splitting the case. When I called Schumacher customer service, I was told that you shouldn’t keep it in the car! What good is a battery you can’t keep with you? Even though it’s a good brand, I cannot recommend this product.

I had the same problem this year. I own 2. One 2 years old and one 3. Yhe newest one. The 120v charger plug never fit in the hole correctly. Had to wrap it around the charger to get it to charge. Both batteries swole up and cracked the cases. They still work tho.

Purchased three Redfuel SL1 jump packs 2 years ago. Removed from vehicles (5Nov2019) to recharge before winter weather sets in (Middle Georgia) and two packs had swollen batteries that separated the plastic cases. One had never been used and one had around 5 jumpstarts on it. Customer service said their jumpstarters should not be stored in vehicles during hot weather because it would cause the batteries to swell. Kind of defeats the purpose of having a portable self contained vehicle jumpstarter. Product worked great when used, just keep in a cool environment and hopefully they will last.
