What is an RV Converter?
There are two types of amperage draws in your RV, AC Amps for your appliances that run off 120V AC power and DC Amps for your appliances that run off 12V DC power.
If you hook up your RV to shore power without a converter, you will be able to run all of your AC appliances, such as your air conditioning, TV, microwave, coffee maker etc.
Your DC appliances, such as your lighting, water pump, furnace, for example, cannot run off AC power – so they would use the power supplied by your 12V DC house batteries.
Once your battery power has run out, without a converter, even though you’re plugged into shore power, you wouldn’t be able to run your DC appliances. To run your 12V DC appliances and recharge your batteries when you’re hooked up to an electrical supply you need an RV converter.
RVs come with a converter fitted as standard. They are an essential piece of kit that is necessary to convert AC power into DC power, keeping your batteries ready for use off grid and your DC appliances powered when you’re hooked up.

Thankfully, RV converter chargers are fairly reasonably priced seeing as they are an essential piece of kit. While you can pick up budget models priced under $100, we recommend opting for the mid-priced range between $100-$200, or more depending on your needs.
As the saying goes, buy cheap, buy twice. There are plenty of RV extras and accessories where you can save big, however, when it comes down to the real essentials, especially all things electrical, we recommend choosing a high quality product even if that means spending quite a bit more.
A good quality RV converter will last you for years. It will also look after your house batteries much better than a cheaper model, saving you money on expensive battery replacements. In fact, spending that extra $100 on a decent converter will probably save you money on batteries in the long run.
So, when it comes down to choosing a new RV converter, if possible, don’t scrimp on the price and end up replacing it (and your batteries) sooner than necessary. At the end of the day, it just ends up being a false economy.
Input Voltage Range
This is the voltage that you will be supplying to your converter from shore power. So, you’ll just need to check that your model is suitable for standard US voltage of 110-120V.
Some RV converters have a much larger range, from around 70V up to around 140V. This can be useful if you are hooking up somewhere with a very unstable power input.
Choose an output voltage that matches your batteries and RV DC circuits. In most cases this will be 12V, although there are some RVs with 24V setups. The output voltage is what your converter converts your shore power into – normally taking 110-120V AC and converting it to 12V DC.
Converting electricity results in some energy loss to heat. While a certain amount of loss is inevitable, the greater the efficiency of your converter, the more available electricity you’ll have to run your appliances.
What’s more, the less efficient your model is, the greater the amount of heat that will be produced. This will result in your converter needing to dissipate this heat with a cooling fan, or to even instigate a thermal shutdown.
Your Rig’s Appliances
Before you think about purchasing a new converter, make sure you list all of your 12V DC appliances in your rig. Then think over what items you are likely to have on at the same time to come up with an average ballpark figure for your needs.
If you’re doing a major RV renovation and have added new appliances, you may need to change out your wiring if you are thinking of investing in a higher capacity converter.
To help you out, here are some common 12V DC appliances with their average draws:
- Light (porch, aisle, overhead) – 1 Amp per light
- Furnace – 10-12 Amps
- Refrigerator (LP gas) – 2 Amps
- 12V TV – 5 Amps
- Ceiling fan – 4 Amps
- Water pump – 4 Amps
Obviously, your exact models will vary, so be sure to check out your actual needs. Your converter’s capacity in Amps represents the total draw of 12V appliances and battery charging that it can simultaneously handle.
45 Amp and 60 Amp versions are popular models suitable for charging large batteries rapidly, as well as powering your 12V DC circuits when you’re plugged into shore power.
No Load Power Consumption
Even if your batteries are fully charged and you are not running any 12V appliances or lighting, your converter will still use a small amount of energy. High energy-efficient models will use the lowest amount of power.
If you are likely to be in situations where you have a limited mains power supply, you’ll want to look for RV converters with the lowest no load power consumption levels.
We recommend choosing a reputable RV electronics brand that has multiple safety features. Here are some of the most common safety features that you’ll want to see included built-in to your new RV converter:
- Over and under voltage protection
- Overheating protection
- Electronic current limiting
- Reverse battery protection
- Short circuit protection
Types Of RV Converters
Here are the most popular types of RV converters on the market, check out which type is the best for your rig and battery-charging needs.
Multi Stage Or Smart Converter
Multi-stage RV converters, also known as smart or intelligent converters, are designed to keep your batteries in prime working order.
Unlike old fashioned one-stage RV converters that simply charge up your batteries at one flat rate, multi-stage models detect your battery level and adapt their voltage accordingly.
Most smart converters feature three distinct charging phases. Firstly, a bulk charge stage where your converter detects your depleted battery levels and charges them rapidly back up at a high voltage.
Then comes the absorption phase at a slightly lower voltage, tailing off towards full charge. Lastly, the float stage trickle charges your battery, keeping it topped up as needed.
Multi-stage converters are essential for long lasting batteries. They can keep your batteries topped up and ready to go during storage periods, as well as minimizing the need for any battery maintenance.
High Output Converter
If you have a large battery bank then you will need a high output converter. The same is also true if you have any large appliances running off your DC circuits.
High output converters will enable you to keep your large battery packs sufficiently topped up, as well as being able to run all of your 12V DC appliances when plugged into shore power.
If you frequently take trips off-grid, you may want to look into extending your battery capacity and investing in a high output converter.
Deck Mount Converter
A deck mount converter gives you much more flexibility when it comes down to installing your converter. Popular with RV remodels, deck mounted versions can be installed in various locations within your RV, such as beneath your counters or wall mounted.
Distribution Panel Converter
If your RV is getting on a bit and you want to upgrade its converter, then a distribution panel converter makes for an easy switch. Often you will find exact panel replacements with new updated high performance converters.
This will keep your interior unchanged, but with a new highly efficient converter that will extend your battery lifespan.
What Are the Benefits of an RV Converter?
There are plenty of benefits to upgrading your RV converter to a newer model. Here are the main benefits of installing a new RV converter.
Protection against Battery Draining – Your converter will keep your batteries topped up, so you won’t have to worry about self-discharge. Multi-stage converters use a float phase to ensure that your batteries are fully charged, so you’ll be ready to get the most out of your trips off grid.
Even Power Distribution – RV converters supply clean, safe DC power. Thanks to their numerous safety protections and automatic shut down systems they protect your RV electrical circuits and give you a reliably even 12V DC distribution for all of your DC appliances.
Seamless Power Supply – By continuously charging up your house batteries, when you decide to hit the road, your fully charged batteries give you a seamless power supply.
So, whether you’re hooked up to shore power or stopping off en route to your next campground, you can still use your lights, run your refrigerator, and benefit from running water.
Long-Lasting Battery – Today’s RV converters are specially designed to take care of your batteries. Upgrading your old, one-stage converter to a multi-stage version will ensure that your batteries last for much longer with less maintenance required.
As we all know, batteries are very expensive, so this is definitely one really important advantage that could even enable you to increase your power bank capabilities, rather than replacing like for like every couple of years.
Safety of Electrical Appliances – A new converter will ensure that all of your 12V DC appliances run smoothly. RV converters utilize proven electrical mechanisms to ensure safe operation and a steady power source.
Numerous safety protections are integrated to ensure an automatic shutdown in the event of any issues, protecting your appliances, circuitry, and RV.
Power Converter vs Battery Charger
Now that you know all there is to know about RV converters, you may be wondering what is the difference between a power converter and a battery charger.
First of all, a power converter is used to convert shore power, AC to DC, so that you can power up your RV’s 12V DC appliances, as well as charging up your battery.
Aside from converting shore power for use in your RV DC circuits, your power converter will also charge up your batteries much faster than a standard battery charger. Power converters are specifically designed nowadays to provide multi-stage charging functionality. This protects your battery from overcharging and keeps it topped up from self discharging.
Battery chargers, aside from their very long charge times, tend to perform one stage charging. If you leave your RV batteries plugged in to a battery charger for a substantial length of time, they will suffer from a reduced lifespan and diminished capacity.
Power Converter vs Inverter
The words inverter and converter are easily mixed up. What’s more, both appliances convert electricity from one form to another. Here are the essential points.
Convert shore power (110-120V AC) to battery power (Normally 12V DC).
Can be used to recharge your house batteries when plugged into mains power.
Also allow you to run your 12V DC RV appliances when plugged into an electrical hook up. For example, your lighting, water pump, refrigerator etc. Any appliance that runs off your 12V DC circuits will need a converter to run off mains AC power.
Convert your DC battery power (usually 12V) into 120V AC power. This enables you to run your AC powered appliances off grid using your RV batteries. AC powered appliances are any items that you could plug into a bricks and mortar home – your microwave, computer, coffee maker, AC etc.
Your inverter uses your battery power which it depletes, whereas a converter uses shore power to replenish battery power.
With so many excellent RV converters on the market at highly competitive price points, there has never been a better time to improve your RV electrics and extend your house battery lifespan. A good RV converter will make your RV much more energy-efficient and could save you a lot of money on new batteries for boondocking.
