- USB 5V/1A Output: A standard USB-A port for charging external devices like smartphones or tablets.
- Charging Port: A USB Type-C port for recharging the internal 10,000mAh battery.
- Power Switch: Toggles the unit on/off.
- Battery Level Indicators: Four LED lights (25%, 50%, 75%, 100%) display the remaining battery charge.

Setup
1. Charging the Power Supply
Before initial use, fully charge the SPS-40B. Connect the provided USB Type-C charging cable to the unit's "Charging Port" and the other end to a 5V/1A USB power source (e.g., a wall adapter, computer USB port, or power bank). The battery level indicators will illuminate to show charging progress. All four LEDs will be solid when fully charged.
2. Connecting Pedals
- Ensure the SPS-40B is turned off.
- Identify the power requirements (voltage and current draw in mA) for each of your pedals. Most guitar pedals require 9V DC.
- Connect one end of the included DC power cables to the appropriate 9V output jacks on the SPS-40B. Match the current rating (100mA or 300mA) to your pedal's needs.
- Connect the other end of the DC power cables to the power input jack of your effect pedals. Ensure correct polarity (center negative is standard for most pedals).

Operating Instructions
1. Powering On/Off
Flip the "POWER" switch on the side of the unit to the "ON" position to activate the power supply. The blue indicator LEDs above each active output will light up, confirming power delivery to your pedals. Flip the switch to "OFF" when not in use to conserve battery life.
2. Monitoring Battery Level
The four green LEDs next to the charging port indicate the remaining battery capacity (25%, 50%, 75%, 100%). Recharge the unit when the battery level is low to ensure uninterrupted performance.
3. Using the USB Output
The "OUT DC 5V/1A" USB-A port can be used to charge compatible USB-powered devices. Simply connect your device's USB charging cable to this port. This feature is active when the power supply is turned on.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the unit. Do not use liquid cleaners or solvents.
- Storage: Store the power supply in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, charge the battery to approximately 50-75% every few months to maintain battery health.
- Battery Care: Avoid completely draining the battery frequently, as this can reduce its lifespan.
Troubleshooting
- No Power to Pedals:
- Ensure the power supply is turned on.
- Check the battery level indicators and recharge if necessary.
- Verify that DC cables are securely connected to both the power supply and the pedals.
- Confirm that the pedal's power requirements (9V DC, correct mA) match the output used.
- Excessive Noise/Hum:
- Ensure all cables are properly shielded and in good condition.
- The SPS-40B features isolated outputs to minimize noise. If noise persists, try isolating the problematic pedal or cable.
- Ensure no ground loops are present in your signal chain.
- USB Device Not Charging:
- Ensure the power supply is turned on.
- Check the USB cable and device for proper connection.
- Verify the device's charging requirements are compatible with 5V/1A output.
