How to Use the Battery

1. Charge the Battery:

The battery pack comes with its own AC charger. You can charge the battery from any 100V ~ 240V AC power outlet.

The battery output voltage range is 20V ~ 29.5V, and its nominal voltage is 25V. When the battery is fully charged, its output voltage is 29.5V. The output voltage will decrease gradually and finally cut off at around 20V. Most of the time, the voltage will be around 24V to 26V.

Output voltage without DD90X DC converter

2. Connect the 24V DC power converter to the battery output cable and then turn on battery

This small size, light weight, high efficiency DC to DC power adapter can convert 10V ~ 30V wide range voltage DC input power to 24V stable voltage DC output power.

Features:

Super small size: dimension is 2.5" x 1.9" x 0.7" ( 63.5 x 48.9 x 16.9mm)

Super light weight: only 2.54 oz (72g)

Super high efficiency: up to 96%

A regular DC converter efficiency is around 80% ~ 85%, which means 15% ~ 20% power will be used by the converter itself. For a 85% efficiency rate power adapter to deliver 90W power, it will take 106W power from a power source ( such as a battery). This DC Converter's efficiency rate is up to 96%, which means only around 4% power will be used by the converter itself. To deliver 90W power, it only needs 94W power from a power source.

Other features:

USB 3.0 port can power and charge iPad,iPhone,Nokia and other different smart USB devices
