OWNER’S MANUAL — Please read before using this equipment.
Your RadioShack Multi-Voltage Power Bank and Charger combines
an AC to DC power adapter, charger, and DC to DC converter to
provide a portable power supply. Whether you are at home or in oth-
er countries, you can use it as a battery charger for Nickel-Metal Hy-
dride (Ni-MH) AA batteries or an AC to DC adapter with AC power
input ranging from 90V to 240V. When traveling, you can install four
Ni-MH AA batteries and the DC to DC converter provides voltages of
3/4.5/6/7.5/9V to your portable DC device. Its features include:
Overload/Short Circuit Protection
— protects the charger and bat-
teries from damage caused by overloads and short circuits.
Charging Protection
— detects battery charge status and stops
charging when the batteries are fully charged.
Safety Guard Timer
— automatically stops charging after 4 hours
to prevent battery overcharging.
Reverse Polarity Protection
— protects the charger and batteries
from damage due to incorrectly installed batteries.
Three LED Status Indicators
— let you know if the power bank is
charging, receiving power or providing DC output.
Your charger is ETL listed to UL standards and meets all applicable
FCC standards.
