*Charging time depends on charger output

If storing for more than 1 month, charge completely before
storage, and recharge approximately every 3 months to avoid full
discharge.

Store in cool temperatures, mild humidity, and away from direct
sunlight (See General specifications). Leaving in a vehicle or
other confined spaces in extreme hot temperatures can lead
to decrease in service life, overheating, or fire. Extreme cold
temperatures below the specified storage range can also harm
performance and service life.

Keep away from corrosive chemicals and gases.
After taking out of storage, inspect visually to make sure KTB1

and all accessories look satisfactory. Allow unit to return to
ambient conditions before recharging or charging other devices.

Specifications subject to change.

CHARGING KTB1

NOTE:

DO NOT attempt to insert other USB connector types into USB-A

or USB-C ports (FIG. B)

NOTE: Charge completely before using. To maximize Li-ion battery
life, see Maintenance and Storage sections (other side).

• Connect the included cable to the USB-C Input/Output port 3, then
connect the other end to any powered USB-A port.

• The battery level indicator LEDs 1 will illuminate (see Table 1).

• A full charge could take 4 to 8 hours, depending on the charger’s output.

OPERATING INSTRUCTIONS

CHARGING DEVICES

NOTE: For best results, use cable provided with your device.

Auto-Sensing ports: The outputs3, 4 will automatically turn on

when a device is connected. NOTE: Certain devices that require very low
current to charge may not be detected by the auto-sensing feature. For
such devices, press the power2 button to begin charging. The status
indicator light may shut-off, but charging will continue on such devices.

1. Connect the cable to your device.

2. Connect the charging cable to one of KTB1’s USB ports3, 4.
The battery status indicator LEDs1 illuminate and charging begins.
LEDs will remain illuminated as long as charging is occurring. The
device being charged should also provide indication that charging
has begun.

3. KTB1 will automatically shut down once charging is complete and
current is no longer being drawn by the device.

TROUBLESHOOTING

The KTB1 has built-in advanced protection to prevent damage to the
battery. The battery has protection for Output over-current, Short­circuit, Voltage drop, and High/Low Temperature. If any of these occur,
refer to Table 3:

TABLE 3

Not Illuminated Solid Green Blinking Green Solid Red Blinking Red

LED

Possible Issue

Over-current or short circuit: KTB1 will automatically shut down.

Disconnect KTB1 from the charger or device being charged.
Wait for 5-seconds and then reconnect the device being charged
or battery charger. Press the power button to reset and begin
charging.

High or low temperature: If KTB1 senses abnormal operating
temperatures, high or low, it will shut down. It will not recharge or
charge until the battery returns to normal operating temperatures
(See Operating Temperature in General Specifications section). All
status LEDs will flash green if the power button is pressed. The LED
status will return to normal (See tables 1 & 2) ONLY after KTB1
senses normal temperatures. Disconnect KTB1 from all chargers

and devices.
Voltage drop: If KTB1's voltage level drops (discharge over time

or simply drained completely), it will enter Low Power Protection
Mode. The bottom LED will illuminate solid red for 2 seconds when
the power button is pressed. KTB1 will NOT support any device
charging at this time, and must be recharged to a minimum of 5%
before the output ports will activate for charging.

KTB1 will not recharge if:

1. The cable is not properly connected to charger output or battery input.

Check connection.

2. The charging cable is damaged.

3. The charging port or device is not able to supply the minimum voltage and
current for charging.

4. The connector on the charger or battery is damaged.

5. An internal battery fault has occurred inside KTB1, preventing the battery
from recharging. See scenarios above. If none apply, KTB1 may be damaged.

Contact Klein Tools Customer Service. DO NOT ATTEMPT TO REPAIR.

Replace with equivalent cable.

Connect to appropriate charging source.

Replace charger or battery.
