Your Dolphin pool cleaner suddenly stops mid-cycle, or the power supply unit buzzes and fails to power on. Before you consider a costly replacement, know this: a faulty power supply is often the culprit, and finding the right Maytronics Dolphin power supply replacement is easier than you think. Whether you need a basic unit for an older model or a smart Bluetooth-enabled version, this guide breaks down the top compatible options to get your cleaner back to work.
Top Maytronics Dolphin Power Supply Replacements
We’ve compared the best replacement power supplies for Dolphin robotic pool cleaners. Each model below offers specific features, compatibility, and reliability to match different needs.
Pros
- Wide compatibility with popular Maytronics Dolphin basic models like Active 10, S50, and Prowler 910.
- Includes a matching 5898412LF power cord for a complete replacement kit.
- Premium thermal management with aluminum heat sink and double insulation.
- Sturdy IP54-rated shell built for outdoor pool environments.
- Generous 12-month warranty adds peace of mind.
Cons
- Only works with basic single-cycle Dolphin cleaners that have a simple on/off control, not smart or programmed models.
- Input power is limited to 100-130VAC, so it won't work directly on 220-240V outlets without a voltage converter.
- Third-party part, not an original Maytronics unit, which some users may consider less trustworthy.
The E-cowlboy 99956034 power supply is a direct replacement for the OEM Maytronics 99956034US-ASSY unit used with several Dolphin robotic pool cleaners that operate on a basic single cleaning cycle. It pairs with a new 5898412LF power cord, making it a complete drop-in solution for owners of models like the Dolphin Active 10, Solo, S50, S100, and Prowler 910.
This basic power supply packs a microprocessor-based PCB and an aluminum heat sink to maintain steady DC 29V 120W output during cleaning. The IP54-rated housing resists splashes and dust, while the double insulation and thermal protection switch guard against overheating. In practice, users get consistent, worry-free power delivery that keeps the cleaner moving through a single automated cycle.
The injection molded body is reinforced for impact, deformation, and corrosion resistance, so it can handle harsh poolside environments. A quick start ON/OFF button and a comfortable carrying handle make daily operation and transport easy. The included 5898412LF cord is designed to match the supply, eliminating guesswork about cable compatibility.
Note that this power supply only supports the input range of 100-130VAC, so it is not suitable for international outlets that use 220-240V without a transformer. It also works only with Dolphin models that use the simple on/off single-cycle control, not with advanced cleaners that have timers, LCD displays, or app connectivity.
For owners of compatible Maytronics Dolphin single-cycle pool cleaners, the E-cowlboy 99956034 replacement power supply offers an affordable, well-built alternative to OEM parts. With the included power cord, solid cooling design, and a 12-month warranty, it delivers reliable performance at a lower cost than many branded repairs.

Key Buying Criteria for Dolphin Power Supplies
When choosing a Maytronics Dolphin power supply, focus on these four critical factors to ensure you pick the right one for your pool cleaner.
- Compatibility: Always match the power supply to your Dolphin model. Check if your cleaner uses a 4-pin or 2-pin connector, and whether it’s a Wi-Fi, Bluetooth, or basic on/off model. Using the wrong type can damage your robot.
- Wattage and Output: Dolphin power supplies typically range from 120W to 180W. Ensure the replacement provides the same wattage as your original to maintain cleaning performance and avoid overloading.
- Additional Features: Some power supplies come with built-in weekly timers or Bluetooth/App connectivity. Timers allow scheduled cleanings, while smart features offer remote control. Decide which conveniences matter to you.
- Included Accessories: Check if the package includes a power cord. Some replacements come with a new cord, saving you the hassle of reusing an old or damaged one. Others require you to keep your existing cord.
Frequently Asked Questions
How do I know if my Dolphin power supply is bad?
Common signs include the power supply not turning on, the robot not charging, intermittent power loss during cleaning, or visible damage like a burnt smell or frayed cord. If your Dolphin isn’t getting power, the power supply is often the first component to check.
Can I use a different wattage power supply for my Dolphin?
It’s crucial to use a power supply with the same wattage as the original. Using a higher wattage can overheat and damage the robot’s internal components, while a lower wattage may cause insufficient power and poor cleaning performance. Always match the wattage to your model’s specifications.
What is the difference between 2-pin and 4-pin Dolphin power supplies?
Dolphin pool cleaners use either a 2-pin round plug or a 4-pin connector. The 4-pin is common on newer models and supports features like timers and Wi-Fi. The 2-pin is typically found on older or basic models. They are not interchangeable, so always check your cleaner’s connector type before purchasing a replacement.
Do all Dolphin power supplies come with a power cord?
No, not all. Some replacements include a new power cord, while others require you to reuse your existing one. Check the product description to see if a cord is included. For example, the For Dolphin Pool Cleaner Power Supply 180W includes a brand-new cord, while the 9995670 Power Supply Parts for Maytronics Dolphin does not.
