This compact power center replaces your WFCO 35-amp distribution panel with an all-in-one converter charger and AC/DC distribution, plus multi-stage charging and automatic lithium detection for a straightforward, reliable upgrade.
Many RV owners upgrade their power center because the factory converter never charged batteries the way it should. Slow recovery times and batteries that never quite reach full are common signs. The WFCO Power Center is designed to fix that by using charging profiles matched to your battery type. Lead-acid batteries receive true 3-stage charging with higher voltage during bulk charging, then step down to normal, and trickle/float stages as they recover. Lithium batteries follow a simpler two-stage process designed for faster, more consistent charging. The result is quicker recharge times and less day-to-day strain on your batteries, helping them last longer and perform more reliably.
Upgrading to lithium batteries is usually about better performance and long-term value, not extra complexity. This power center uses WFCO's Auto-Detect technology to recognize lithium or lead-acid batteries and apply the correct charging profile automatically. There are no switches to set and no settings to guess at. Once installed, it charges your batteries the way they are designed to be charged, helping you get the faster recovery, longer service life, and consistent performance that make lithium a worthwhile upgrade for your RV.
Instead of juggling separate components, the WFCO Power Center combines your AC breaker panel, DC fuse block, and converter into one compact unit. This helps keep wiring organized and reduces clutter in tight RV compartments. With six AC circuits and six DC circuits, it provides capacity for everyday RV essentials like outlets, lighting, appliances, and onboard electronics. The power center accepts standard residential breakers and automotive fuses (not included). You can check the product manual for recommended brands and styles, which are easy to find and purchase from most hardware or RV stores.
Electrical upgrades only bring peace of mind if they operate safely day after day. This power center is built with protections against overheating, over-current conditions, and reverse polarity connections, so a wiring mistake or heavy load doesn't turn into a bigger problem. LED indicator lights provide quick visual feedback to help identify power and fault conditions, making it easier to spot issues during troubleshooting. The cooling fan is designed to pull air in and exhaust it out the front of the unit, which helps move heat away from the components instead of letting it build up behind the panel. That matters in tight RV compartments where airflow is limited. If operating limits are ever exceeded, the system can shut itself down to protect the electronics. It's built-in safety that's reassuring when you're upgrading battery types or replacing an older converter that didn't manage heat nearly as well.
This WF-8735-AD is designed to replace many factory-installed WFCO 35-amp power centers, which is why it fits so well in common RV power center locations. It can also be used as a replacement for other brands with similar layouts and capacity. Because every RV is a little different, it's still important to verify cutout dimensions and wiring before installing. Some applications may require minor adjustments depending on the original layout. If you'd rather leave the job to a professional you can use etrailer's installer locator to find a qualified shop near you and get help with installation.

Great product and great service
Perfect size for our little vintage cam per
Direct replacement/upgrade to what i had. E-trailer is always tops.
Easy to install. Very little modification to the installation opening. Installed in an Aliner Columbia. Works great!
It was a perfect match to my old one! Just plug and play couldn't have been easier
A drop-in replacement for the original. The new converter auto detects the battery type and adapts the charging protocol. Now, my 190AH LiFePo battery fully charges.
Does the job. Installation takes some time, but this is a direct replacement for the WF-8735 (non-lithium), so it's just a matter of disconnecting/reconnecting wires. Same exact size too, so it screws into the same holes. Only negative is this one has a small green light that always stays on, so if your converter is in a very visible location, it may annoy you at night.
Item arrived quickly and in good shape. Other than having to slightly increase the mounting location it installed easily and works great. I like how the cooling fan only runs when it's needed and not constantly like the old unit.
The product was a replacement and upgrade and worked perfectly. Siobhan did an excellent job helping me navigate the choices and got the converter delivered to me on time for me to install before my trip. Frosty beverages of choice for her! Thank you!!
It was plugged and play, works great so far.
