JUNPENG’s WF-8935-MBA provides 35A DC output with a three-stage charging approach and auto-detect features. It adapts charging to the battery type and keeps the output within a safe range (13.2V floating, 13.6V absorption, and 14.4V bulk). The design emphasizes efficient cooling and load-based fan control, helping prevent overheating during extended camps. It is suitable for a range of RV setups, especially where space is at a premium and quick battery maintenance is needed between camping stints.
PowerMax PM3-35 Power Supply
The PM3-35 from PowerMax is a compact 35A converter with three-stage charging. It converts 110/120V AC to DC for RV batteries and 12V systems, providing efficient charging with a current-limiting design that reduces risk of overload. It includes built-in protections against overheating and short circuits, making it a robust option for RV upgrades and maintenance. This model is noted for straightforward installation and reliable performance in a wide range of RV and travel trailer configurations.
Bonbo PD4135KW2BV 35 Amp RV Converter
The Bonbo PD4135KW2BV is designed as a 35A RV power converter panel, replacing WFCO 8735-style units. It provides 13.6V DC output with a 35A rating and features multiple fuse holders for DC distribution. The unit emphasizes safety with reverse battery protection and clear LED indicators for troubleshooting. It’s positioned as a drop-in replacement for older WFCO panels, suitable for upgrading electrical distribution in mid-size RVs while improving reliability and battery management.
Buying Guide
- Battery compatibility: Check whether the converter supports lead-acid, AGM, Gel, and lithium chemistries. Some models include lithium-specific charging profiles or auto-detect features to optimize charging for different batteries.
- Charging stages: Four-stage charging (bulk, absorption, float, and equalization) tends to deliver smoother, safer battery maintenance and longer life. Three-stage charging can suffice for basic needs but may be less flexible for diverse battery packs.
- Output and wiring: Ensure the unit’s 12V output (35A in these cases) aligns with your RV’s 12V system demands. Verify available DC terminal connections and fuse distribution to match your existing setup.
- Safety and protections: Look for overcurrent, overvoltage, short-circuit, reverse polarity, and thermal protection. A unit with auto cooling or fan regulation helps maintain performance in hot climates.
- Installation: Consider dimensions, mounting options, and whether the unit uses a standard 110V/120V AC input. Some panels are easier to retrofit in older RVs than others, so check compatibility with your current distribution panel.
- Reliability and warranty: Choose models with positive field reports and solid manufacturer warranties. A lengthier warranty can provide peace of mind in remote locations.
- Maintenance and monitoring: Some converters include monitoring indicators or simple onboard diagnostics to simplify troubleshooting and service intervals.
- Noise and cooling: Fans vary in speed and noise. If you camp near quiet areas, consider units with efficient cooling that minimize noise.
When selecting a 35 amp RV power converter, assess how you use 12V systems on your rig. For boondocking or longer off-grid stays, a four-stage charger with lithium compatibility offers robust battery care. If you predominantly rely on campground hookups, a reliable three-stage or four-stage unit that stabilizes shore power input and protects sensitive devices remains a solid choice. Consider replacement compatibility with your current WFCO or similar panels to ensure a smoother installation.
