How To Use - NOCO Genius BOOST HD GB70 User Manual & Warranty

How To Use

Step 1: Charge the GB70.
The GB70 comes partially charged out of the box and needs to be fully charged prior to use. Connect the GB70
using the included USB Charge Cable to the USB IN port and the USB car charger. It can also be recharged from any
USB powered port, like an AC adapter, car charger, laptop and more. The USB IN port is rated at 2.1 Amps to ensure
safe and efficient charging of the internal lithium battery. Due to FCC regulations, we recommend not to charge and
discharge the unit at the same time. The time to recharge a GB70 will differ based on the discharge level and the
power source used. Actual results may vary due to battery conditions.
When recharging, the charge level of the internal battery is indicated by the Charge LEDs. The LEDs will slowly pulse 'On' and 'Off' and become
solid until all four Charge LEDs are on. When the battery is fully charged, the Green 100% LED will be solid, and the 25%, 50% and 75% Charge
LEDs will turn "Off". From time to time, the Green 100% LED will pulse indicating maintenance charging is occuring.

USB Charging (Up to 10W): Connect the GB70 using the included USB Charge Cable to the USB IN port and a powered USB port, like an AC adapter, car charger, laptop and

Powering Your 12V Devices.
Connect the 12V Cable to the "12V OUT" port on the GB70, and the other end to the Female 12V Plug (12V AUX/ Cigarette Lighter Port.) Plug-in any standard 12V device (Up to
15A) with a 12V plug and turn the GB70 "On" to start powering your device.
Step 2: Connect to the Battery.
Carefully read and understand the vehicle owner's manual on specific precautions and recommended methods for jump starting the vehicle. Make sure to determine the
voltage and chemistry of the battery by referring to your battery owner's manual prior to using this product. The GB70 is for jump starting 12-volt lead-acid batteries only.
Before connecting to the battery, verify that you have a 12-volt lead-acid battery. The GB70 is not suitable for any other type of battery. Identify the correct polarity of the battery
terminals on the battery. The positive battery terminal is typically marked by these letters or symbol (POS,P,+). The negative battery terminal is typically marked by these letters or
symbol (NEG,N,-). Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts. The below instructions are for a negative ground system (most common).
If your vehicle is a positive ground system (very uncommon), follow the below instructions in reverse order.
