TERMINOLOGY
DETAILS
CHANNEL
A circuit module that implement independent functions.
Channels are working parallel, with no interference between
each.
USB PORT
USB 2.0 has four leads. VBUS and GND are power leads. D+
and D- are data leads. Standard USB 2.0 ports has a current
limit of 0.5A (such as PC, notebook). Normal USB Battery
Charger has a current limit of 1.5A or 2A. USB port on VoltBot
is specially fabricated and can stand 3A and higher current
(Depend on the lead material, lead thickness, contact resistor
and contact force).
TOUCH KEY
Capacitor sensor, when a finger or an object comes near and
changes the electric field, it will generate a touch signal.
Calibrated every power-up to fit the environment.
DC INPUT
Normal 5.5*2.5 socket, but it only fits for 5.5*2.5*12mm plug.
5.5*2.5*9mm plug is too short to reach the leads.
LIGHT SENSOR
Sense the environment light to auto-adjust the LCD back-
light.
UART
3.3V TTL UART，115200 Baud, 8N1, no parity, no flow-control.
Meant to be used to connect with external MCU, PLC or PC.
RESERVED PORT
A reserved port, do not use it.
PRESS KEY
Single press: enable touch-key for a while
Double press: switch on/off screen
Long press: switch on/off sound

Note: 1. For pulsed current (below 250ms) larger than 11A would cause the channel being
totally shut-down. It needs a re-power-up to recover.
2: The contact resistor of USB connector limits the continuous current. Considerable
temperature rise would occur if current is larger than 3A. Due to contact resistor is not
predictable, you can touch the plug to make sure the temperature is OK. If the temperature

4. Quick Start Guide
1) Charge a Normal Phone
1. Connect Power Input
2. Channel 4 for example. Check channel 4 is under charger mode
3. Check channel 4 has quick charge switch on
4. Connect data-cable in channel 4 and start charging.
2) Charge an iPhone X (PD support)
1. Plug-in the A-to-C (Type-C) extender.
2. Follow the steps in previous section and adapt a C to Lightening Data Cable.
3. The iPhone 8P/9P/X/XR/Xmax will start quickcharge and auto set the voltage into 9V.
3) Power a Gadget
1. Make sure the input voltage required by the gadget (possible: 5V, 3.3V, 9V)
2. Press the side-key once. There will be something shown on the screen. You will see 1324
is the right code to configure output.
3. Touch these symbols as 1324 in a row.
4. If you touched the wrong button, touch any key 3~4 times to see “Fail”, or press the side-
