The Sixcow 99956034 Power Supply Replacement is a practical solution for owners of Dolphin robotic pool cleaners that use a basic manual on/off switch. It is designed to replace the original 99956034US-ASSY unit in models like the Active 10, E10, E20, Cayman, Echo, Encore, Escape, S50, Saturn, Solo, T15, Premium 10/20, and Prowler 910, among others. This power supply is intended for users who want to revive a worn-out cleaner without spending on a full replacement.
Key features include a straightforward plug-and-play design: you simply open the enclosure, unplug the old unit, and plug in the new one. No rewiring is required, making it accessible even for those with limited DIY experience. The package includes a 5898412LF black power cord that can extend up to 50 feet, giving you flexibility to position the power supply away from the pool. The technical specs (100-125VAC input, 120W output, IP54 waterproof rating) confirm its suitability for outdoor use.
Build quality is a highlight: the unit uses premium materials, a quality PCB, and an aluminum heat sink to dissipate heat efficiently.

Buying Guide: What to Look for in a Dolphin Power Supply Replacement
Compatibility with Your Dolphin Model
The most critical factor is ensuring the power supply matches your cleaner’s connector type and model generation. Dolphin robotic cleaners use different power configurations: 2‑pin, 3‑pin, or 4‑pin connectors, and some newer models require Wi‑Fi enabled supplies. The 4‑pin systems are common on models like Nautilus CC Plus, DX3, and Neptune. In contrast, basic on/off models such as Active 10, E10, and S50 use the 99956034 style supply. Always verify your existing unit’s part number and connector before ordering. For a broader look at compatible parts, visit our Replacement Parts category.
Power Output and Performance
Power supplies for Dolphin cleaners typically range from 120W to 180W. Higher wattage units (180W) are designed for larger models or those with more demanding cleaning cycles. If your original unit was 180W, replacing it with a lower wattage could reduce cleaning efficiency. Conversely, using a 180W supply on a 120W model is safe as long as the voltage matches (usually under 30V DC). Look for units with stable output and built-in thermal protection to avoid overheating during long runs.
Build Quality and Durability
Pool environments are harsh: moisture, heat, and UV exposure can degrade electronics quickly. Choose a power supply with an IP54 or higher waterproof rating, a corrosion-resistant enclosure, and an aluminum heat sink for efficient cooling. Units that include a handle make transport easier, and those with a built-in power cord save you the hassle of finding a separate cable. The best replacement power supplies use high-quality PCB boards and anti-corrosion coatings to withstand years of outdoor use. If you’re also replacing wheels or tracks, see our best pool cleaner replacement wheels for dolphin guide.
Extra Features: Timers and Power Switches
Some aftermarket power supplies include a built-in weekly timer that lets you schedule cleaning cycles daily, every other day, or every third day. This is a convenient upgrade if your original unit lacked scheduling. A dedicated on/off switch also adds safety and convenience, eliminating the need to unplug the cord after each use. However, if your Dolphin model uses Wi‑Fi for scheduling, a basic unit without a timer will still work, but you’ll lose app control.

Final Thoughts
After evaluating six power supplies, two stand out for different needs. For owners of 4‑pin Dolphin models like the Nautilus CC Plus or DX3, the For Dolphin Pool Cleaner Power Supply 180W offers strong 180W output, a built-in weekly timer, and a convenient on/off switch, making it a versatile upgrade. If you have a basic on/off model such as the Active 10 or E10 and want a reliable replacement that includes the power cord and is IP54 waterproof, the 99956034 Power Supply Replacement for Dolphin from sixcow delivers solid performance at a reasonable investment. Whichever you choose, restoring your Dolphin’s power supply will bring back the sparkling pool you rely on.

Frequently Asked Questions
How do I know which power supply my Dolphin pool cleaner needs?
Check the part number on your existing power supply unit, usually printed on a label. Also note the connector type: 2‑pin, 3‑pin, or 4‑pin. Models with Wi‑Fi require a supply like the Dolphin Genuine Replacement Part (99956083‑ASSYV10). If you’re unsure, consult your cleaner’s manual or contact the manufacturer. For general guidance, our essential spare parts for dolphin robotic pool cleaners article covers compatibility basics.
Can I use a 180W power supply on a cleaner that originally used 120W?
Yes, as long as the voltage output is the same (typically under 30V DC) and the connector matches. The cleaner will only draw the power it needs, so a higher wattage supply is safe and can even provide a bit of headroom for consistent performance. However, using a 120W supply on a model designed for 180W may cause insufficient cleaning or overheating.
Are aftermarket power supplies as reliable as genuine Dolphin parts?
Many aftermarket units from reputable brands like sixcow and Hihitomorrow use high-quality components and offer features like waterproof housings and thermal protection. They often cost less than genuine Dolphin parts while providing comparable reliability. Always check customer reviews and warranty terms. Genuine Dolphin parts are certified and may offer better long-term support, but aftermarket options can be a cost-effective alternative.
My Dolphin cleaner has a Wi‑Fi control box. Can I replace it with a basic power supply?
No, Wi‑Fi models require a power supply that supports the communication protocol, such as the Dolphin Genuine Replacement Part 99956083‑ASSYV10. Using a basic on/off supply will not allow the cleaner to receive scheduling commands from the app. If you want to keep Wi‑Fi functionality, stick with a compatible Wi‑Fi power supply.
