JOYO JP-905 DC 9V 500mA Pedal Power Charger Adapter
Smart and Professional IC chips for noise reduction and isolation safe protection performance. It works with most brands pedals is requiring tip negative 9V to minimize or eliminate the need to change batteries.
WARNING: Critical Compatibility Check REQUIRED Before Purchase!
Please verify 3 key specs:
1. POLARITY MUST MATCH: Our adapter is CENTER NEGATIVE
? NOT compatible with CENTER POSITIVE equipment
2. CURRENT RATING: Output: 500mA (0.5A). Safe for devices requiring =500mA
3. VERIFY YOUR DEVICE:
Check: Symbol near DC jack (center negative), Voltage (must be 9V)
Min. Current (e.g., "Requires 300mA+" ? OK; "Needs 600mA" ? No)
Professional Effect Pedal Power Adapter
DC 9V 500mA Pedal Power Supply (Center Negative)
- With Precise plug-in and chip component design for noise reduction and isolation safe protection performance, works for most brands of guitar effect pedals (center negative).
- Use a new high-frequency and low-resistance smart IC filter capacitor to filter out AC noise. The internal filter inductor is a clean and stable DC power for the output.
Details
Precise IC Chip Component
- Noise reduction and short circuit protection.
- High-efficient and low-consumption DC adapter
Center Negative (-) Design
- Barrel Size: 5.5*2.1mm
- Compatible with most effects pedal models
Pure Copper Wire
- Premium PVC + low impedance pure copper wire.
- Good insulation and low impedance.
Better Contacted Output Port
- With protection of short circuit, overcurrent, overheat, overload , the power supply work is safer.
