Housed in a lightweight aluminum alloy case, it features short circuit and overcurrent protection on each output, bright blue LED indicators for easy monitoring, and includes 10 link power cables. Ideal for millennial pros seeking reliable, compact, and versatile pedalboard power without breaking the bank. ## Description Product Description Short-Circuit Protection All 10 outputs in this unit have separate short-circuit protection, i.e. short circuit in one channel won't affect other channels' function. Under the circumstances of all LED lights on, LED light of the short-circuited channel will off, while lights in the other normal channels are still on. This helps locating the faults when there were short circuits among many effectors. Switch For LED Lights Turn the switch towards those LED lights, normally all lights would go on after the power is connected. If you don't want all LED lights, please turn the switch back Independent and stable power supply The power supplies of the Donner series of effects have absolutely independent power interfaces. It has an 18V power supply, and all outputs are independent of each other through its voltage regulator circuit. The aluminum alloy material is strong and compact and easy to carry. Donner Pedal Power Supply DP-1 Powers For 9V、12V or 18V Pedal. Power: AC 100v-240V. Input: DC 18V. Output 7 way 9V 100mA 1 way 9V 500mA 1 way 12V 100mA 1 way 18V 100mA Attention Incorrect polarity would damage this unit, please make sure correct positive and negative polar before wiring. Specifications Material: Aluminium Alloy Light weight and portable Dimension:150x50x30mm Net weight: 196g Color: black Review: Great power supply. Would recommend - Great little power supply. Using it now on my peddleboard for about 4 months and no issues. Its compact and have had no noise issues since installing it. Was using a daisy chain before and was getting unwanted noise and faint beeping. This eliminated the issue completely. There are ones that are a lot more expensive out there but this one did the job for me. Makes sure to check the power consumption of all your peddles 1st to make sure you have enough of each type of supply. This bank has 6 x 9v 100mA, 2 x 9v 500mA, 1 x 12v 500mA and 1 x 18v 500mA. A very good selction for this price point. Using the wrong supply for the peddle can cause issues. Appears to be individually isolated and has worked well for me. It is in a nice sturdy metal shell. It was also smaller than I thought it would be, which is an added bonus. Lights up well too and nice to have the feature to turn off the lights if you want. Would recommend Review: Good value, inexpensive power supply for the average user. - This is a decent power supply for the money. It is aimed mainly at the user who has a large number of relatively low-powered analogue pedals - overdrives, fuzzes, distortions, etc. - and a smaller number of pedals that typically require more current - reverb, chorus, delay, multieffect and so on - plus the ability to power the odd 12V or 18V pedal. All ten outlets are DC only: eight 9V, one 12V, and one 18V. Of the eight 9V outlets, six are limited to 100mA each, and two to 500mA. The 12V and 18V outlets are also 500mA each. All the outlets use the standard 2.1mm plug, centre negative. However you attach the effects, the current drain must not exceed the rated power for the outlet in question. The total power for the whole unit is stated to be 18 watts (18V x 1000mA). All the outlets will accept daisy chains, which can be used safely so long as the total current draw does not exceed the stated rating of the particular outlet. Note that these power ratings are maximums, not optimums. As usual, it's intelligent to avoid placing excessive demands on the power supply, particularly with digital effects. What are the limitations? None of the channels provides the ability to lower the supplied voltage, so 'sagging' the power - for example, to a fuzz - isn't possible. There is no facility to supply AC power, for those pedals that require it: all outlets are DC only. (Most pedals are DC: check before ordering.) Running a positive ground pedal is not possible. The 12V and 18V channels are not switchable, and will supply only those voltages: they can't be used as additional 9V outlets. This is offset by the ability to run a daisychain from one of the 9V channels if necessary. The individual outlets are short-circuit and overload protected, so if one fails it won't bring the whole unit down: but they are not 'isolated' in the true sense (galvanic isolation). If you want complete isolation of each outlet, you will have to pay a lot more. The unit is not intended to cope with pedals that place unusual demands on the power supply, such as: power draw in excess of 500mA; voltages other than those stated; sockets and plugs that are not 2.1mm (without adapters); AC power; or positive ground. This means that if you use - for example - a lot of Strymon, Line 6, or other high-power modulation-type pedals, or boutique copies of unusual old pedals, you would do well to look elsewhere (but if you can afford those, I assume that you wouldn't be looking for a cheap power supply anyway). Otherwise, for the ordinary user at home, or for light gigging, this inexpensive unit should be fine. Just make sure to check your pedals for voltage, current draw and polarity, and don't exceed the maximum power rating for any one channel. The unit has an all-metal case, appears to be decently constructed, and comes with its own 18V AC adapter. All necessary cables are supplied. The bright blue LEDs can be turned off if they are a visual distraction. I'm happy with my purchase. ## Features - 10 Isolated output, isolated short circuit/overcurrent protected - Material: aluminium alloy, light weight and portable - Bright blue LED for pedal board lighting & short circuit indicate - Includes link power cables (10pcs) - Power: AC 100v-240v input: DC 18v powers for 9v 12v or 18v pedal ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0774K83RM | | Amperage | 100 Milliamps | | Best Sellers Rank | 1,541 in Musical Instruments & DJ ( See Top 100 in Musical Instruments & DJ ) 1 in Power Attenuators | | Brand | Donner | | Brand Name | Donner | | Colour | DP-1 | | Connector Type | 1/4 inch audio | | Controls Type | Knob | | Country of Origin | China | | Customer Reviews | 4.4 out of 5 stars 896 Reviews | | Hardware Interface | 1/4-inch Audio | | Included Components | 10pcs link power cables | | Item Dimensions | 50 x 30 x 150 millimetres | | Item Dimensions L x W x H | 5L x 3W x 15H centimetres | | Item Weight | 196 Grams | | Item weight | 196 Grams | | Manufacturer | Donner | | Manufacturer Part Number | EC813 | | Model Name | EC813 | | Model Number | EC813 | | Power Source | Corded Electric | | Product Warranty | 1 year. | | Product dimensions | 5L x 3W x 15H centimetres | | Signal Format | Analog | | Style | Classic | | Unit Count | 10 Count | | Voltage | 18 Volts, 9 Volts | ## Product Details - **Brand:** Donner - **Colour:** DP-1 - **Item weight:** 196 Grams - **Product dimensions:** 5L x 3W x 15H centimetres - **Style:** Classic ## Images ![Power Supply, Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedals (DP-1) - Image 1](https://m.media-amazon.com/images/I/61-FK3cD1oL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great power supply.

I have had a few issues with grounding/earthing noise, noticeably disappears when I tough the footswitch on any of the pedals with my hand, I probably need to investigate which pedals are causing it, or see if there's an ordering issue. Probably not as good as a more expensive fully isolated power supply, but then again it's about a quarter of the price. ## Frequently Bought Together - Donner Power Supply, Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedals (DP-1) - SONICAKE 6 Inch Guitar Patch Cable Guitar Effect Pedal Cables Noiseless 1/4" Right Angle TS Mono Cords for Guitar/Bass Effect Pedals Black 6 Pack - GOKKO Guitar Pedal Board 13.8" x 11" Guitar Pedalboard with Gig Bag and Mounting Tape (Build-in Power Supply Bracket) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/49026480-power-supply-guitar-pedal-power-supply-10-isolated-dc-output](https://www.desertcart.co.th/products/49026480-power-supply-guitar-pedal-power-supply-10-isolated-dc-output) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-14*
