Overview
TekChargeTM MP1820, a pocket-sized rechargeable battery pack, provides emergency charging
and power for many popular portable devices making it a versatile solution for the power needs
of most of your mobile products, on the road, and at home.
TekCharge MP1820 connects to your device in two ways: The power pack can connect to a
device using the user’s own USB device cable. In this case, the USB connector plugs into the
battery, and the opposite end into the mobile device, like iPad, iPhone or iPod.
As a second option, mini USB and micro USB adapter tips are included for connection to any 5V
devices that uses a micro or mini USB cable to charge, including current models of most popular
mobile phones, e-Readers and other portable devices. Additional adapters not included with
TekCharge MP1820 are available from Tekkeon for a nominal fee.
As an added bonus, TekCharge MP1820 includes a flashlight so you have emergency light at
your fingertips.

Storing TekCharge MP1820
Lithium ion batteries must be used consistently for maximum performance. Therefore, if you do
not use the battery often, once a month you should discharge and recharge the battery to 40% (if
it will be transported) or 70% (for long term storage), and store it in a cool and dry environment
at a temperature between 50° and 86° F (10° and 30°C). You may permanently damage your
battery’s capacity by storing the battery without any capacity in the cell. It is important that
you do not leave the battery in the interior of a vehicle parked in the sun, or exposed to direct
sunlight for extended periods of time.
Prolonging Battery Life
Extreme heat and cold will affect your battery’s performance. At temperatures above 80°F
(27°C), the battery will discharge more quickly, and in colder temperatures, the battery won’t
charge well. Therefore, it is recommended that the battery is used at room temperature, or
between 68°F to 77°F (20°C to 25°C). The battery must be used at temperatures between 32°F
to 104°F (0°C to 40°C). It is not recommended that the battery is charged in temperatures above
104°F (40°C), and the battery capacity may be permanently damaged if you use your battery in
temperatures higher than 140°F (60°C). You may damage the battery even more if you charge
the device in these temperatures. You may find that using the battery in a very cold environment
decreases the battery capacity. Unlike the effects of a hot environment, this is a temporary
condition. Once warmed, the battery will return to its previous capacity.

USER GUIDE
Using TekCharge MP1820
TekCharge can power or charge any portable device that requires 5V. If your device has a DC
jack with center negative polarity, do not power the device with TekCharge as it does not support
center negative polarity.

Charging TekCharge MP1820
TekCharge should be charged when initially removed from the package, or when the capacity
indicator lamp turns orange to indicate that the battery has less than 20% capacity. As an option,
you can simultaneously charge both TekCharge and the connected device.
1. Plug the included mini USB adapter tip into the retractable input/output cord.
2. Plug the mini USB tip into the mini USB port (5V IN).
3. Plug the USB plug on the opposite end of the input/output cord into a USB port on a computer
or a USB power adapter, and connect to a wall socket.
4. To charge only TekCharge, slide the power switch to OFF. If the battery level is less than 80%,
the lamp will be orange. When the battery is more than 80% charged, the lamp will change to
green. The battery will be fully charged after 8-10 hours.
Or
To charge both TekCharge and the connected device, slide the power switch to ON.
TekCharge will be charged first, and will in turn charge the connected device. This connection
will work only for devices that charge slower than the input power (500mA). If the connected
device draws more power than the input power, TekCharge will be depleted at some point.
5. When the battery is fully charged, unplug the input/output cord from both TekCharge and the
computer or charger.

Viewing the Power Capacity
Charging
When TekCharge is being charged, the capacity indicator lamp will light to indicate the amount
of power in the battery:
Orange: 0% - 80% capacity
Green: 80% - 100% capacity
Discharging
When TekCharge is connected to and charging a device, or when the power switch is ON and
TekCharge is not connected to a device, the capacity indicator lamp will be constantly lit to
indicate the amount of power remaining in the battery:
Green: 20% - 100% capacity
Orange: 0% - 20% capacity
Charging a Device Using an Adapter
1. Select the adapter that fits securely into the power jack on your portable device and plug it
into the input/output cord.
2. Insert the USB plug on the input/output cord into the USB port on the end of TekCharge.
3. Connect the adapter plug into the power jack on your portable device.
4. Slide the TekCharge power switch to ON to provide power through the USB port.
5. Turn on the portable device and use it as you would normally. While connected, TekCharge
will power and/or charge your device.
Or
Leave the portable device turned off and TekCharge will charge the device battery.
6 When finished, slide the power switch to OFF and unplug the power output cord from
TekCharge and your device.
NOTE: If none of the included adapters fits snugly into your portable device power jack, please
go to our web site at www.tekkeon.com/MP1820adapters to determine which adapter plug
you need for your device. You can obtain most adapters through the web site, or by contacting
Tekkeon by phone at 888-787-5888 or 949-788-9228. If available through Tekkeon, the adapter
will be sent to you for a nominal fee.

USER GUIDE
Charging a Device Using Your Device USB Cable
You can use your own device USB cable to connect to your device. However, for devices with
mini or micro USB power ports, it is highly recommended that the included mini or micro USB
adapter tips with retractable cable are used in place of the device USB cable.
1. Insert the USB plug on the device cable into the USB port on TekCharge.
2. Connect the USB cable into the power jack on your
portable device.
3. Slide the TekCharge power switch to ON
to provide power through the USB port.
4. Turn on the portable device and use it
as you would normally. While connected,
TekCharge will power and/or charge your device.
Or
Leave the portable device turned off and TekCharge will charge the device battery.
5. When finished, unplug the USB cable from TekCharge and your device.
TIP: You can use the emergency flashlight while charging your device.
Troubleshooting
If TekCharge does not power your portable device or charge the device battery, take these
steps:
1. Check that the input/output cord is connected to both TekCharge and the portable device,
and that the adapter plug fits snugly into the power jack on your portable device. If not,
try another adapter.
2. If connecting TekCharge to a device with a DC jack, verify that the polarity of the device
power jack is center positive. If the polarity is center negative, do not power the device with
TekCharge as it does not support center negative.

3. Determine if your device is designed with charging circuitry that limits the input voltage. If
so, TekCharge may not be able to power or charge the device. (For example, if a device is
designed to accept only a 4.2V input, then TekCharge may not be able to power or charge
the device.)
If your iPad, iPhone or iPod does not sync while TekCharge is connected to a computer:
1. Ensure that TekCharge is connected to your computer using a USB to mini USB data cable.
(The included retractable cable provides power only, and does not support syncing.)
If TekCharge shuts down for five seconds to five minutes after you connect a device:
1. Connect TekCharge to a USB power adapter or to your computer.
2. Check the power capacity on TekCharge. If the battery is empty or too low, recharge the
battery.
3. If the TekCharge capacity indicator is green, check the connected device to ensure the output
current does not exceed 1A.
