2000 Amp UltraSafe Lithium Jump Starter
The GB70 is a portable lithium-ion battery jump starter pack that delivers
2,000-amps (15,700 J3S) for jump starting a dead battery in seconds. It
features a patented safety technology that provides spark-proof connections
and reverse polarity protection making safe and easy for anyone to use. It's
a powerful battery booster that doubles as a portable power source for
recharging USB devices, like a smartphone, tablet and more, or powering
12-volt devices, like a tire inflator, power inverter and much more.
Designed for a car, boat, RV, truck and more with gas engines up to 8
liters, and diesel engines up to 6 liters.
Everything you need on one interface.
We designed the user interface to be simple and easy to understand. LED
status indicators display the internal lithium batteries charge level
and charging status. Error indicators show when connected in reverse
polarity or temporarily disabled for thermal protection. Simply turn on
the LED flashlight, recharge a USB device, or use manual override for
deeply discharged batteries.
More power, a fraction of the size.
Compared to an equivalent 1,850-amp lead-acid jump starter, the GB70
provides 15,700 joules versus 6,950 joules. Not only is it 2X more
powerful, it's nearly 4X smaller and lighter.
Joules, not peaks amps.
Joules start vehicles, not peak amps. The average vehicle jump
starts in 1-3 seconds, making peak amps somewhat worthless. But
actual power over time illustrates a battery booster's real
Jump starts per charge.
A powerful lithium jump starter capable of jump starting up to 40
vehicles on a single charge. It's rated for over 1,000 charge cycles
and holds its charge level for over a year with minimal power loss.
Multi-function jump starter.
Jump start cars, boats, RVs, and trucks, as well as diesel pickups,
hot rods, classic cars and more. Even recharge USB devices, like a
smartphone, and power 12V devices, like a tire inflator.
Recharge 3X faster with XGC.
The GB70 is completely rechargeable from any USB-powered port, like a
wall charger, car charger or laptop. But it takes 7 hours. With XGC, you
can charge directly from the vehicle's 12-volt auxiliary port and
utilize its rapid charge technology to recharge 3X faster — just over 2
hours. Go from zero charge to jump starting in just 15 minutes.
Power 12V tire inflators, power inverters and more.
It's more than just battery jump starter pack, it is portable 12-volt
power. Go anywhere and power your favorite 12-volt devices, like a tire
inflator, power inverter, coffee maker, fan and much more.
Stay charged. Power your USB devices on the go.
How many times will a GB70 recharge my device?
The built in 2.1A USB out port can power all of your USB devices, such
as smartphones, GoPro cameras, wireless headphones, and more. The
battery capacity inside of your iPhone, for example, is measured in
“milliamp-hours," or mAh—a way of measuring how long the device will
last. Devices that are frequently being used, like phones and cameras,
often require more power to run all day than the device’s battery is
rated for. Boost's battery pack extends the life and running time of
your device. Plus, powering your device from an external battery pack
will reduce the internal battery’s charge cycles, extending the usable
