The Berfea 10M Connection Cable is a reliable replacement cable designed for Husqvarna Automower and Gardena robotic lawnmower charging stations. It is ideal for homeowners who need to extend the reach of their transformer or replace a damaged original cable. This cable is compatible with a wide range of models from 2013 onward, making it a versatile solution for many users.
Standout features include double insulated copper wire for safe and efficient power delivery, and a waterproof construction that allows the cable to be buried directly in the lawn.

Also, the cable is 10 meters fixed; if you need a longer run, you may need to purchase an additional extension or reposition the transformer. No adapters are included for non-standard connectors.
Overall, the Berfea Connection Cable offers excellent value for money. It delivers the same performance as the original at a lower cost, with added durability and weather resistance. If your robotic mower uses a compatible transformer, this cable is a smart upgrade or replacement choice.

Build quality is solid for a third party product. T POWER uses brand new components, and the charger feels durable enough for everyday use. The connectors fit securely into the mower's charging port, and the included cable length is adequate for typical setups. However, it is important to confirm your mower model is on the compatibility list before purchase.
A potential drawback is limited compatibility: this charger is not for 150W systems or older Husqvarna models like the 320, 330X, 420, 430X, 450X, and similar. Additionally, as a newer product with few reviews, some buyers may prefer a more established brand. The lack of a universal plug adapter could also be an inconvenience for international users.

The Husqvarna Genuine 590442404 Power Supply is an OEM replacement part designed exclusively for the Automower 430X and 430XH models. It serves as a direct substitute for the original part number 590941504, making it essential for owners who need a reliable charging unit for their robotic lawn mower.
Standout features include its genuine Husqvarna engineering, which ensures a precise fit and consistent power delivery.

Real-world performance is expected to match the original equipment, providing stable charging cycles for the mower's battery.
The build quality reflects Husqvarna's reputation for durability, with a sturdy housing and reliable internal components. The black color and compact form factor integrate seamlessly with the mower's design. However, given the price point, some users may consider aftermarket options, though compatibility and longevity remain uncertain with non-OEM parts.
A potential drawback is the limited compatibility with only specific 430X and 430XH models. Additionally, as of now, there are no verified user reviews, so long-term performance data is unavailable. It is critical to confirm your mower's exact model and serial number before purchasing, as visual similarity does not guarantee fit.
Overall, if you own a compatible Husqvarna Automower and need a dependable replacement power supply, this OEM part is a safe choice. It offers peace of mind through guaranteed compatibility and brand support, making it worth the investment for maintaining your mower's performance.
Pros
- Affordable replacement for expensive OEM cables
- Waterproof and durable for outdoor use
- 3-meter length offers flexible charging station placement

The Berfea Replacement Connection Cable is a practical and cost-effective solution for owners of Husqvarna Automower robotic lawnmowers. Designed to replace original transformer cables (part numbers 579 82 51-03, 580 43 38-03, and 580 43 38-06), this 3-meter adapter connects your charging station to the power supply, giving you more flexibility in where you place the station.
Standout features include its double-insulated copper wire and waterproof construction. The cable can be buried directly in the lawn without fear of moisture damage, and the thicker insulation resists cuts from mower blades.

Always check your mower's manufacturing date before ordering. Additionally, there are zero customer reviews yet, so long-term reliability is unproven.
Overall, the Berfea cable is a smart buy for anyone needing a replacement or extended reach for their robotic mower. It offers OEM-level compatibility at a lower cost, with durable materials that handle outdoor conditions. If your mower matches the supported years, this is a reliable choice.

Buying Guide: What to Look for in a Husqvarna Automower Power Supply
Compatibility with Your Mower Model and Year
Not all power supplies work with every Automower. Husqvarna uses two main charging systems: a 28V standard (for models like the 105, 310, 315) and a 150W high-power system (for the 320, 330X, 430X, 450X, and newer). Using the wrong charger can damage your mower or fail to charge it. Always check your mower’s model and year of manufacture before buying. For example, the Husqvarna Genuine 590442404 US Power Supply 430X is designed specifically for 150W models. If you need a replacement for older models, see our best husqvarna automower wheel kits guide for traction upgrades.
Power Output: 28V vs. 150W
The voltage and wattage must match your charging station. The 28V chargers (like the 28V Charger for Husqvarna Automower 105 115H 310) output 2A and are for smaller mowers. The 150W chargers (like the 150W 28V Charger for Husqvarna Automower 320 330X) output higher current for larger batteries. A mismatch can cause slow charging or no charging at all. Verify your original part number (e.g., 584862604 or 590941504) to ensure a perfect fit.
Cable Length and Flexibility
If you are replacing a damaged cable or need to move the charging station, cable length matters. Options range from 3 meters (like the Berfea Replacement Connection Cable Wire) to 10 meters (like the Connection Cable for Transformer Power). Longer cables give more flexibility to place the station away from outlets. For larger yards, the VHBW 33ft cable offers generous reach. Ensure the connectors match your transformer and dock.
OEM vs. Aftermarket Reliability
Genuine Husqvarna parts like the Husqvarna Genuine 590442404 US Power Supply 430X guarantee exact fit and performance, but they cost more. Aftermarket brands such as Berfea, T POWER, and vhbw offer certified alternatives that meet safety standards (ETL listed) at lower prices. Many include warranties. For critical components like the main charger, OEM is often recommended. For cables, aftermarket options are generally reliable. Also check our Best Robot Mower Blade Sharpener guide to keep blades sharp.
Final Thoughts
Choosing the right power supply for your Husqvarna Automower comes down to your mower’s model and your budget. For a direct OEM replacement that guarantees compatibility and durability, the Husqvarna Genuine 590442404 US Power Supply 430X is the top pick for 150W models. If you need a cost-effective cable upgrade or a spare charger for a 28V mower, the 28V Charger for Husqvarna Automower 105 115H 310 from T POWER delivers verified performance at a fraction of the cost. Whichever you choose, double-check your mower’s year and part number to avoid compatibility issues.

Frequently Asked Questions
What power supply does my Husqvarna Automower need?
Check your mower’s model and year. Models like the Automower 105, 310, and 315 use a 28V 2A charger (part numbers 529532604, 584862604). Models like the 320, 330X, 430X, and 450X require a 150W charger (part numbers 590442404, 590941504). Look at your original charger label or consult the manual.
Can I use a 28V charger on a 150W Automower?
No. A 28V standard charger cannot supply enough power for 150W models. It will either not charge or charge very slowly. Using the wrong charger may also damage the battery or charging electronics. Always match the wattage rating.
How long does a Husqvarna Automower power supply last?
With proper use, a power supply can last 3 to 5 years. Exposure to moisture, heat, or physical damage can shorten its life. If your charger stops working or shows signs of wear (cracked cable, flickering LED), replace it promptly. For cable replacements, consider the VHBW 33ft Low Voltage Cable for Husqvarna for a durable upgrade.
Is it safe to use a third-party replacement charger?
Yes, if the aftermarket charger is certified (ETL or UL listed) and matches your mower’s voltage and wattage. Brands like T POWER and Berfea offer certified options that meet safety standards. Avoid uncertified chargers from unknown sellers. For more on maintaining your mower, see our Top Husqvarna 420 iQ Replacement Parts guide.
