6 Best RV Converter Chargers in 2026: A Practical RV Guide
Six 55 to 80 amp RV converter chargers compared by charge-current math, voltage modes and cooling, so you can size one to a big battery bank.
By Hardcastle's RV Editors
11 min read6 products evaluated
Most converter roundups sort by amp rating, but the job you hire a converter charger for is the second half of its name: putting current into a battery bank while the rig's 12V loads also pull. A 200Ah lithium bank can accept a lot more than a 45 amp box can spare, and that gap, not the label, decides how long you wait. As a rule of thumb, an effective charge rate is the converter's amps minus the loads you leave running, and at 13.6 volts every 10 amps is about 136 watts of DC.
We compared six aftermarket chargers from 55 to 80 amps, priced from $72.81 to $169.90, with the charge angle in mind: voltage modes, stage descriptions, cooling and the battery sizes each listing actually claims. For name-brand OEM replacement parts see our factory-part guide, and for a specific size see the amp-specific pages. Here the question is which unit fits a bigger or lithium-heavy battery bank without wasting money.

How We Built This Shortlist
Each pick was assessed across 5 criteria weighted for real-world use.
- Charge headroom
- We converted each amp rating into approximate DC watts at 13.6 volts and compared how much room is left for the battery after house loads.
- Voltage control
- We checked for numbered voltage steps, an adjustable range or lithium mode instead of a bare compatibility claim.
- Stage description
- We looked at whether stages are named (Boost, Normal, Trickle, Storage) and whether a lead-acid desulfation stage might apply to lithium.
- Stated battery size
- Some listings tie a unit to a battery range, and we noted those because they can conflict with the unit's amp rating.
- Price and certification
- We weighed the $72.81 to $169.90 spread against listed marks such as CE, FCC, RoHS and protection lists.
What Matters Before You Choose an RV Converter Charger
Key buying criteria so you get the right fit the first time.
Charge current after loads
A converter's amps are shared between the battery and the rig, so a 55 amp unit with 15 amps of loads leaves about 40 for the battery. A 200Ah bank half empty then needs roughly 2.5 hours at that rate, and longer as charge tapers. Add your running loads, subtract from the rating, and compare to the battery's maximum charge current.
Battery's own charge limit
Many batteries limit charge current to a fraction of their capacity, so a bigger charger does not charge faster. A 100Ah battery with a 50 amp limit gains nothing from an 80 amp box. Read the battery spec for the maximum charge current before choosing a size.
Lithium voltage step
Lithium wants a steady absorb voltage near 14.4 to 14.6 volts and does not need an equalization or desulfation stage. A unit without a 14.6 volt option may undercharge it. Look for a numbered step or a LiFePO4 mode and check it against the battery maker's spec.
Stage naming
A Desulfation or equalization stage can reach high voltages for lead-acid, and on lithium it is harmful. If a listing names stages, see which are skipped in lithium mode. A listing with no stage names, like the WAVLINK 80A, leaves you to check the manual.
Heat and cooling
An 80 amp unit at 13.6 volts moves around 1,088 watts, and heat shortens electronics life. A temperature-triggered fan with a metal housing helps. Check the listing for a fan description, and allow clearance around the unit.
Seller and certification clarity
Three picks here come from seller names rather than established converter brands, and only some list marks like CE, FCC or RoHS. None here lists a UL mark in the feature text. Check the return window and ask for documentation before hardwiring a high-current unit.
Match an RV Converter Charger to Your RV
By Battery Bank Size
Match the charger to how much current the bank can accept after your loads.
| Your situation | Recommended pick | Why |
|---|---|---|
| 200Ah or larger bank, many 12V loads | WAVLINK 80A | 80 amps leaves the most headroom |
| 100Ah to 200Ah lithium bank | CARMTEK 55A | Lithium claim with six protections |
| 100Ah to 200Ah bank on a budget | MWXNE 55A | Named stages and lithium switch for $79.99 |
| Lead-acid trailer with a WF-9800 bay | Hihitomorrow 65A | Names a WF-9800 replacement fit |
| 55Ah to 70Ah bank, lowest cost | VEVOR 65A | Listing is written for that bank size |

By Budget
| Budget | Recommended pick |
|---|---|
| Under $80 | VEVOR 65A or MWXNE 55A |
| $125 to $135 | Hihitomorrow 65A or KSGNY 55A |
| $145 to $175 | WAVLINK 80A or CARMTEK 55A |
More Amps vs More Detail
- More amps
- The WAVLINK 80A and the VEVOR 65A give the most current per dollar. They suit larger banks, but the WAVLINK lists no stages and the VEVOR ties itself to small batteries.
- More listing detail
- The CARMTEK 55A and MWXNE 55A spell out lithium support, protections and stages at 55 amps. They charge a smaller bank well but have less headroom.
Most buyers with a 100Ah to 200Ah bank are better served by detailed 55 amp listings than by an 80 amp box with little explanation.
By Charge Voltage Control
| Your need | Recommended pick | Why |
|---|---|---|
| Numbered 14.6V lithium step | MWXNE 55A | Offers 13.0, 14.6 and 16.5V modes |
| Wide adjustable range | WAVLINK 80A | 13.0V to 16.5V range stated |
| Lithium and lead-acid listed with protections | CARMTEK 55A | Six protections, adjustable range |
| Four-stage lead-acid cycle | Hihitomorrow 65A | Boost, Normal, Storage, Desulfation |

For Boondocking Rigs With a Big Lithium Bank Specifically
- Look for
- Enough output to feed loads and the bank at once, a numbered lithium voltage and cooling that keeps the box from derating when it runs for hours.
- In this comparison
- The WAVLINK 80A has the most headroom at about 1,088 watts of DC, and the CARMTEK 55A has the clearest lithium listing. The MWXNE 55A is the cheaper way to get a 14.6 volt step.
When to Spend More
- Spend more if
- You have a large bank or want the most explicit lithium listing; the WAVLINK 80A offers headroom and the CARMTEK 55A offers detail.
- Save if
- Your bank is mid-size and you can set a mode by hand; the MWXNE 55A at $79.99 or VEVOR 65A at $72.81 do the job for about half the price.
Before You Bring One Home
What is the difference between a converter and a converter charger?
A converter changes 120V AC to 12V DC to run loads. A converter charger also charges the battery in stages. Most RV converters today are both, so the name is mainly a search habit.
Will an 80 amp charger damage a small battery?
It can if the battery's charge current limit is lower than the output. Many small batteries accept only a fraction of capacity. Use a smaller unit or check for a current limit, and note the VEVOR 65A is pitched at 55Ah to 70Ah banks.
Is the CARMTEK worth $90 more than the MWXNE?
If you want the six listed protections and a clearer lithium statement, maybe. The MWXNE gives named voltage steps and stages for $79.99, so most buyers will pick it for value.
How do I set these chargers for lithium?
Use the lithium or LiFePO4 mode where it exists, or the 14.6 volt step, after checking your battery's absorb voltage. Do not leave a 16.5 volt step selected on a battery.
Can these replace a factory WFCO or Progressive unit?
Only if the cutout and connectors match. The Hihitomorrow 65A names a WF-9800 fit, and the rest are generic. See our factory-part guide for exact OEM matches.
How do I check that my charger is working correctly?
Measure battery voltage with a meter while plugged in. A lead-acid battery should sit near 13.2 to 14.4 volts in float or absorb, and a lithium bank should follow its maker's spec. A reading far below suggests a loose lug or failing unit.
