Detailed Review

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.

Detailed Review

The E-cowlboy 99956034 replacement power supply is designed for owners of Dolphin robotic pool cleaners who need a reliable, cost-effective alternative to OEM parts. It works with popular models like the Active 10, E10, Solo, Echo, Escape, T15, and Premium 10/20, making it a versatile choice for many pool owners.

Standout features include IP54 waterproofing, which protects against splashes and dust, and a built-in handle for easy carrying. The unit includes the 5898412LF power cord, so you have everything needed for installation. In real-world use, this means less downtime and a straightforward swap of your old unit.

Build quality is solid with an aluminum heat sink and corrosion-resistant components that handle high temperatures and humidity. The upgraded PCB ensures stable current output, which should keep your cleaner running smoothly. However, the power supply is limited to 120W and lacks Wi-Fi, so it won't support app-based models or heavier-duty cleaners.

A potential drawback is the lack of customer reviews, making it hard to gauge long-term performance. Also, the output voltage is under 30V DC, which is safe but may not be suitable for all pool sizes.

Overall, this power supply is a practical, budget-friendly option for Dolphin owners seeking a durable replacement without the OEM price tag. The included warranty and money-back guarantee add confidence. If your cleaner is compatible, it's a smart buy.

Buying Guide

Compatibility with Your Dolphin Model

Not every power supply works with every Dolphin cleaner. These units are designed for basic models without Wi-Fi, such as the Active 10, E10, Echo, Encore, S50, Solo, Escape, T15, Premium 10, and Premium 20. Before ordering, confirm your cleaner uses an on/off switch only. The three products we cover all list the same compatible models, but double-check your unit’s model number. If you need a replacement for a different part, see our best pool cleaner replacement cable guide.

Build Quality and Weather Resistance

A poolside power supply must withstand moisture, heat, and occasional splashes. Look for an IP54 rating, which means it is protected against dust and water spray. All three units claim IP54 protection, but materials matter. The sixcow and E-cowlboy models emphasize aluminum heat sinks and corrosion-resistant components, while the Hihitomorrow unit uses a quality PCB board with anti-corrosion treatment. A durable power supply lasts longer and maintains stable output.

Included Power Cord

Each product comes with a 5898412LF black power cord, which plugs into the right side of the power supply. The cord length allows placement up to 50 feet away, giving you flexibility to position the unit safely away from the pool edge. Having the cord included saves you a separate purchase and ensures compatibility. If your old cord is damaged, this replacement covers everything you need.

Installation Effort

All three power supplies are plug-and-play. You simply open the existing enclosure, unplug the old unit, and plug in the new one. No rewiring or special tools required. This makes them accessible even for those with limited DIY experience. For more tips on maintaining your pool cleaner, read our best pool cleaner replacement wheels article.

After evaluating these three power supplies, we recommend the 99956034 Power Supply Replacement for Dolphin from sixcow for its outstanding build quality, thermal protection, and high customer rating. For a slightly more affordable option with the same compatibility, the 99956034 Power Supply Parts for Dolphin Active 10 from Hihitomorrow offers reliable performance and a straightforward installation. Both units restore your Dolphin cleaner to peak efficiency without the cost of a new machine.

Frequently Asked Questions

How do I know if my pool cleaner power supply is failing?
Common signs include the cleaner not powering on, intermittent operation, or a burnt smell from the power supply unit. If your Dolphin stops moving or the LED lights flicker, the power supply may be the issue. Replacing it with a compatible unit often resolves the problem.

Can I use a different power supply for my Dolphin pool cleaner?
Only use a power supply specifically designed for your model. The 99956034 replacement works with Dolphin cleaners that have a manual on/off switch and no Wi-Fi. Using an incompatible unit could damage the cleaner or pose a safety risk. Always verify your model number before purchasing.

Is the 99956034 power supply waterproof?
These units have an IP54 rating, meaning they are splash-proof and dust-resistant. They are safe for outdoor use near the pool but should not be submerged. Place the power supply at least a few feet from the water edge to avoid direct splashing. For more on protecting your equipment, see our best pool cleaner wall climbing brush guide.

How do I install a replacement power supply?
