Ultimate Freedom: STRICH SPS-40B Rechargeable Pedal Power Supply Review
Ditch the cables with the STRICH SPS-40B. Featuring a 10,000mAh battery and 10 isolated outputs, this rechargeable supply offers 10+ hours of noiseless power for any gig.
For many guitarists, the "spaghetti mess" of power cables is the most frustrating part of a pedalboard. Between hunting for a wall outlet at a dive bar and dealing with 60-cycle hum, power is often a headache. The STRICH SPS-40B Rechargeable Power Supply aims to cut the cord entirely.
STRICH SPS-40B Rechargeable Pedal Power Supply Review
STRICH kindly sent us their SPS-40B Rechargeable Guitar Pedal Power Supply to test and review. We used a variety of pedals (and also tested the unit with some small analogue Behringer synths, including the TD-3) over a number of days, so that we could give you our verdict on this affordable rechargeable power supply. Expectations were high given our positive history with the brand’s previous offerings. Fortunately, this latest piece of gear maintains the same rigorous standards we’ve seen across their entire catalog.
This is a useful tool designed to liberate musicians from the constraints of traditional wall outlets. Equipped with a massive 10,000 mAh lithium-ion****battery, this portable power station is the perfect companion for buskers, touring professionals, and home studio enthusiasts alike. Making it an ideal unit to keep handy either in a gig bag or as part of a more permanent portable pedalboard setup.
The battery will easily handle a gig, and the indicator light shows how much charge is left in the unit. Obviously, the time will vary depending on the draw of your pedals. We managed to use it for a good few hours straight with no problems, using various effect pedals, which should be enough for most live performances.
By providing clean, isolated power to up to ten pedals simultaneously, the SPS-40B eliminates the common "hum and buzz" associated with cheap wall adapters while offering the freedom to perform anywhere—from street corners to stages with limited power access. Its compact, rugged design doesn't just power your tone; it streamlines your entire setup, even featuring a dedicated USB port to keep your mobile devices charged during long rehearsals or live sets.
The overall build quality of this power supply is very good; it comes with all the necessary connections and includes clear instructions for use.

Top Features & Performance
1. Cord-Free Convenience
The standout feature is the wireless capability. Once charged, you no longer need to be tethered to a wall. This is perfect for outdoor gigs or quick studio sessions where you don't want to trip over extra cables.
2. Isolated Power for Clean Tone
Noise is the enemy of any pedalboard. The SPS-40B features isolated outputs that prevent ground-loop hum and signal interference. Even with high-gain distortion pedals or digital delays, the signal remains impressively clean and transparent.
3. Smart Monitoring
One of the most practical additions is the 4-level LED battery indicator. It displays power in increments (25%, 50%, 75%, 100%), so you’ll never be surprised by a dead battery in the middle of a set.
4. Versatile Charging
Beyond powering your pedals, the inclusion of a 5V USB port is a brilliant touch. It allows you to keep your phone or tablet (perfect for digital sheet music or backing tracks) charged simultaneously.
Pros and Cons
The Good:
- Massive Battery: Easily lasts through long rehearsals.
- Cost-Effective: Cheaper than buying individual rechargeable batteries or high-end boutique power bricks.
- Build Quality: Rugged aluminum housing can handle the rigors of touring.
- Noise-Free: Isolated outputs ensure a professional-grade signal.
The Not-So-Good:
- No Wall Adapter Included: While it comes with a USB charging cable, you’ll need to provide your own 5V power brick (like a phone charger) to power it.
- Output Limits: With a max of 300 mA on the high-draw ports, it may struggle with power-hungry digital multi-effects units (like a Line 6 Helix or Strymon BigSky), which often require 500 mA.
Frequently Asked Questions (FAQ)
Q: How long does it take to charge? A: Depending on the wattage of your USB adapter, it typically takes 4-6 hours to reach a full charge. Q: Can I use it while it is plugged into the wall? A: Yes, it can function as a traditional power supply while charging, though it is designed primarily for wireless use. Q: Will it power my "Big Box" digital pedals? A: Check your pedal's manual. The SPS-40B offers two 300mA ports. If your pedal requires more than 300mA, it is not recommended for use with this unit. Q: Is it heavy? A: At only 600g, it is significantly lighter than many transformer-based power supplies, making it ideal for travel boards.
Final Thoughts
The STRICH SPS-40B is a robust, quiet, and incredibly convenient solution for the modern guitarist. It eliminates the need for power strips and long extension cords, making your setup faster and cleaner. If you use standard 9V pedals (or synths) and want the freedom to play anywhere, this is a must-have addition to your rig.
It offers great value for money and is perfect for musicians on the move.
