This review covers four top contenders, from genuine Dolphin parts to compatible third-party options, so you can get your cleaner back to work quickly. Whether you own a Wi-Fi model or a basic 4-pin unit, we’ve got you covered.
We’ve evaluated each product based on compatibility, power output, ease of installation, and build quality. No fluff, just the facts you need to choose the right replacement. Check out our full category of pool cleaner reviews for more insights.
Pros
- Plug-and-play installation with no rewiring needed
- Broad compatibility with many Dolphin and Maytronics models
- Includes a long 50-foot power cord for flexible outlet placement
- Durable build with IP54 waterproof rating and thermal protection
- Restores cleaning performance of existing robotic pool cleaners
Cons
- Only compatible with manual on/off Dolphin models (no WiFi or smart features)
- Aftermarket brand (Sixcow) may not match OEM build quality over time
- No customer reviews yet, so long-term reliability is unverified
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. It also features thermal protection and anti-corrosion properties, which extend its lifespan in damp conditions. The included handle adds convenience for moving or hanging the unit. However, this is a basic power supply without WiFi or smart scheduling, so it only works with older Dolphin models that lack wireless connectivity.
Potential drawbacks are few but worth noting. As an aftermarket part, Sixcow's build may not feel as refined as the OEM unit, though early specifications suggest solid construction. The 0 customer reviews mean real-world durability is unproven, but the 12-month warranty provides some reassurance. Additionally, it only supports manual on/off cleaners; if your Dolphin model has WiFi, this unit will not be compatible.
Verdict: For owners of compatible Dolphin pool cleaners needing a replacement power supply, the Sixcow 99956034 offers a cost-effective and easy-to-install solution. Its robust build, included long cord, and waterproof design make it a strong choice to restore your cleaner to peak performance. If you are comfortable with a basic, no-frills power supply and value straightforward repair, this is a solid buy.
Buying Guide
Compatibility with Your Dolphin Model
Not all power supplies work with every Dolphin cleaner. The connector type matters: some use a 4-pin plug, others a 2-pin or Wi-Fi system. Check your existing power supply’s part number or the model of your cleaner before buying. For example, the For Dolphin Pool Cleaner Power Supply 180W from E-cowlboy is designed for 4-pin models only, while the sixcow unit fits manual on/off models without Wi-Fi.
Genuine Dolphin parts like the 99956083-ASSYV10 are certified for specific Wi-Fi models such as the M400 or Nautilus CC Supreme. If you’re unsure, consult your cleaner’s manual or look for the part number on the old supply. For more on maintaining your cleaner, see our dolphin nautilus CC replacement brush review.
Power Output (Wattage)
Power supplies come in 120W and 180W variants. The wattage determines how much energy your cleaner gets. For larger pools or models with strong motors, 180W is often recommended. The E-cowlboy unit delivers 180W, while the sixcow and one Dolphin genuine part (99956085-ASSYV4) provide 120W. The Dolphin 99956083-ASSYV10 offers 180W for Wi-Fi models.
Choose the wattage that matches your original supply. Using a lower wattage may reduce cleaning performance, but it won’t damage the cleaner. If your old unit was 180W, stick with that. For smaller cleaners, 120W is sufficient.
Timer and Switch Features
Convenience features like a built-in weekly timer and an on/off switch can save you time and hassle. The E-cowlboy unit includes a weekly scheduler that lets you set cleaning days and a power switch for easy control. The sixcow unit is a basic model without a timer, but it does have a handle and thermal protection. The genuine Dolphin parts are designed for Wi-Fi models, so scheduling is handled through the app.
If you want automated cleaning without relying on Wi-Fi, the E-cowlboy is a strong choice. For those who prefer app control, the Dolphin genuine parts are the way to go. Explore other pool cleaner accessories to enhance your setup.
Build Quality and Durability
A replacement power supply should last for years. Look for features like waterproofing (IP54 rating), thermal protection, and aluminum heat sinks. The sixcow unit boasts an IP54 rating and a high-quality PCB board. The genuine Dolphin parts come with Maytronics certification, ensuring they meet OEM standards. The E-cowlboy unit includes a new power cord and a sturdy housing.
All four products are designed for outdoor or damp environments. Check user feedback for longevity, but given the ratings (4.0 to 4.9), these should be reliable. For more on pool cleaner maintenance, read our dolphin active brush replacement review.
Final Thoughts
After evaluating compatibility, power, features, and build quality, two products stand out for different needs. If you own a 4-pin Dolphin model and want a timer and switch, the For Dolphin Pool Cleaner Power Supply 180W from E-cowlboy offers excellent value and high wattage. For those with a Wi-Fi model like the M400 or Nautilus CC Supreme, the Dolphin Genuine Replacement Part 99956083-ASSYV10 provides a certified, reliable 180W supply that integrates seamlessly with your cleaner’s smart features. Either way, you’ll restore your pool cleaner to peak performance.

Frequently Asked Questions
How do I know which Dolphin power supply is compatible with my cleaner?
Check the model number on your Dolphin cleaner or the part number on the existing power supply. The connector type (4-pin, 2-pin, or Wi-Fi) is key. For 4-pin models, the E-cowlboy unit works. For Wi-Fi models, use a genuine Dolphin part like 99956083-ASSYV10. For manual on/off models without Wi-Fi, the sixcow unit is a good fit.
Can I use a third-party power supply for my Dolphin pool cleaner?
Yes, third-party units like those from E-cowlboy and sixcow are designed to be compatible. They often match or exceed OEM specifications. Just ensure the connector type and wattage match your cleaner. Many users have successfully replaced their original supplies with these alternatives without issues.
What is the difference between 120W and 180W power supplies?
Wattage indicates power output. A 180W supply provides more energy, which can improve cleaning performance in larger pools or with powerful motors. A 120W supply is sufficient for smaller cleaners. Always use the wattage recommended by the manufacturer. Using a lower wattage won’t harm your cleaner, but it may reduce effectiveness.
How long do Dolphin power supplies last?
With proper care, a power supply can last 3 to 5 years. Factors include usage frequency, exposure to moisture, and power surges. To extend lifespan, keep the unit in a dry, shaded area and unplug it during storms. For more tips, check our above ground pool cleaners guide.
