Selecting the Right Adaptaplug Adapter
An Adaptaplug adapter allows you to match the size and polarity of your
portable device's DC input jack.
One Adaptaplug adapter, of your choice, comes with the power bank when you
purchase it. Other sizes are available at your local RadioShack store.
Adapter Compatibility
The power adapter's output voltage setting must be exactly the same number
as the voltage your portable device requires. Also, the power adapter's
current must be equal to or more than the current your portable device
requires.
ADAPTER'S MAXIMUM
DEVICE'S RATING OUTPUT CURRENT
3, 4.5, or 6 VDC 1000 mA
7.5 VDC 800 mA
9 VDC 660 mA
1. Set the output selector switch to the correct setting for your
portable device (3/4.5/6/7.5/9 VDC).
2. If the power jack on your portable device is marked (-0-C.-0+), align
TIP on the power cord with (+) on the Adaptaplug.
If the power jack is marked (+0-C.-0-), align TIP on the power cord
with (-) on the Adaptaplug.
IMPORTANT: Your portable device must be rated 3, 4.5, 6, 7.5, or 9 VDC
(see "Adapter Compatibility" above).
Plugging the adapter into a portable device that has different
ratings could damage the portable device or the adapter.
Be sure to set the correct TIP polarity. Incorrect TIP polarity
can damage the portable device or the adapter.
Using as an AC to DC Adapter
1. Disconnect the charger from AC power to change the output voltage
selector.
CAUTION: Do not change the 3/4.5/6/7.5/9V setting while the charger is
connected to AC power. Doing so could damage the charger.
2. Use a flat-blade screwdriver to rotate 3/4.5/6/7.5/9V to the desired
output voltage.
3. Insert the supplied DC output cord's plug into the charger's DC output
jack.
4. For devices which require 3/4.5/6/7.5/9V DC power, connect an
Adaptaplug adapter to the output socket of the supplied DC cord,
taking care to orient the plug for proper polarity.
5. Plug the charger into a standard AC outlet. The POWER indicator
lights. Then insert the other end of the Adaptaplug into the device's
power jack. The DC OUTPUT indicator lights.
If the DC OUTPUT indicator turns off when the charger is in use, the
output current is beyond specifications and the overload/short circuit
protection is activated. Disconnect the charger from AC power then
from the device. Check the current requirement of your portable device
If the required current is within specification (see" Adapter
Compatibility," above), wait for at least 10 seconds before
reconnecting the adapter. Reconnect the adapter to the AC power
first, then to the device. If the indicator still flashes or turns
off, the power bank or your portable device may be defective.
If the required current does not match this adapter's current, do not
use this power bank.
Using as a DC to DC Converter
You can use the power bank as a DC to DC converter to power devices which
require 3/4.5/6/7.5/9V or DC power.
You can use Ni-Cd, Ni-MH, or alkaline batteries when you use the power
bank as a DC to DC converter.
WARNING: Use only four of the same type of rechargeable batteries. Do not
mix Ni-Cd and Ni-MH batteries together.
CAUTIONS: Use only fresh, fully charged batteries of the required size and
recommended type.
Do not mix old and new batteries or different types of batteries
(alkaline or rechargeable).
Follow these steps to use the power bank as a DC to DC converter.
1. Follow the instructions under "Using as an AC to DC Adapter," above,
Steps 2-4 to connect the DC cord to the charger.
2. Lift the battery chamber cover and insert four fully charged
rechargeable or alkaline AA batteries into the battery chambers as
indicated by the polarity symbols (+ and -) marked inside each bay.
3. Close the battery chamber cover. If the cable is connected to the DC
output jack, the DC OUTPUT indicator lights.
4. Insert the other end of the Adaptaplug into the device's power jack.
When the batteries are low, the DC OUTPUT indicator turns off or flashes.
Recharge or replace the batteries.
WARNING: Dispose of old batteries promptly and properly. Do not burn or
bury them.
If you do not plan to use the charger with batteries for a month, remove
the batteries. Batteries can leak chemicals that can destroy electronic
parts.
Notes: You must insert four AA batteries into the chambers or the power
supply will not provide DC power to the device you want to power.
If the DC OUTPUT indicator turns off when the charger is in use,
the output current is beyond specifications and the overload/short
circuit protection is activated or the batteries might be low.
Disconnect the DC cord and the device from the charger and check
the current requirement of your portable device (see "Adapter
Compatibility," above).
If the required current is within specification (see "Adapter
Compatibility," above), wait at least 10 seconds. Reconnect the
DC cord to the charger, then to the device. If the indicator still
flashes or turns off, the power bank or your portable device may be
defective.
If the required current does not match this adapter's current, do
not use this power bank.
When the batteries are low, the DC OUTPUT indicator turns off or
flashes. Recharge or replace the batteries.
To conserve power when the charger is in standby, always disconnect
the DC cord from the charger.
Using as a Charger
Notes: It is normal for the batteries to become warm while charging.
See "Specifications" in Faxback Doc. # 63902 for indoor and outdoor
charging temperatures. Cold batteries will not charge fully. If the
area is too warm, the batteries can permanently lose their ability
to charge.
Charging Batteries
You can charge two or four AA size, Ni-Cd or Ni-MH batteries with this
charger.
CAUTION: Do not charge both Ni-Cd and Ni-MH batteries at the same time.
Follow these steps to charge batteries.
Note: Be sure the DC output cord is disconnected from the power bank. The
charger will not operate when the DC output cord is connected.
1. Lift the battery chamber cover and insert two or four AA rechargeable
batteries into the charging chamber(s) as indicated by the polarity
symbols (+ and -) marked inside the bay's chambers.
Note: If you choose to charge two AA batteries, insert them into the
left (#1) chamber.
2. Plug the charger into a standard AC outlet. The POWER and CHARGING
indicators light.
Notes: If the CHARGING indicator flashes, a faulty battery or short
circuit exists, or an alkaline battery is in the chambers.
Replace the battery. If the CHARGING indicator still flashes,
contact your local RadioShack store for assistance.
If the supplied DC cord's plug is connected to the charger's
Output jack, the charger does not charge the batteries and the
CHARGING indicator does not light. The DC OUTPUT indicator
lights. Once the DC cord is disconnected from the charger, the
charger starts charging the batteries and the CHARGING
indicator lights.
If two batteries installed in the left chamber have been
charging for over five minutes, and you then install two
batteries in the right chamber, the charger does not charge
the batteries in the right chamber.
3. When the batteries are fully charged, the CHARGING indicator turns
off. Unplug the charger from the AC outlet, then remove the batteries
from the charger or you may begin using it as a DC to DC power bank
for your portable device.
