For 30 amp service the Camco PowerGrip 50-ft 30-amp is the best RV power cord — the length you actually need in heavy 10-gauge copper. For 50 amp rigs the Camco Power Grip 30-ft 50-amp is the equivalent, and the PlugSaf 50-ft 30-amp is the value alternative.
How We Picked
We compared shore power cords on conductor gauge (the single thing that decides whether the cord runs cool and holds voltage), the quality of the moulded ends and grip handles, weather and UV rating on the jacket, and how they behave in cold weather when cheap jackets go stiff. Length matters more than people expect, because campground pedestals are routinely on the wrong side of the site. Pair the cord with our guides to RV surge protectors, RV batteries, and portable generators.
1. Best 30 Amp: Camco PowerGrip 50-Ft 30-Amp RV Extension Cord
Camco PowerGrip 50-Ft 30-Amp RV Extension Cord
Camco
- 50 feet of reach for awkward pedestals
- Heavy 10-gauge copper conductors
- Moulded PowerGrip handle for pulling plugs
- Weather and UV resistant jacket
- 4.8★ from 4,082 owners
Why we picked it: Camco is the default name in RV electrical for good reason, and this is the cord most 30 amp rigs should carry. Fifty feet sounds excessive until the pedestal is behind you and across the site; the alternative is daisy-chaining adapters, which is how people melt connectors. Ten-gauge copper keeps the cord cool and holds voltage at the far end, which directly affects whether the air conditioner keeps running on a hot afternoon. The moulded grip is not a gimmick — a wet cord end is genuinely hard to pull without one.
2. Best 50 Amp: Camco Power Grip 30-Ft 50-Amp RV Extension Cord
Camco Power Grip 30-Ft 50-Amp RV Extension Cord
Camco
- 50 amp, rated 125/250V
- Heavy four-conductor construction
- Moulded grip handles at both ends
- The most-reviewed cord in this guide
- 4.8★ from 5,958 owners
Why we picked it: Fifty amp service is four-wire and carries roughly twice the load, which makes cheap cords a genuinely bad idea — there is real current in this cable. This Camco is the one most big rigs end up with, and with nearly six thousand owner ratings at 4.8 stars it is the most road-tested product in this guide. Thirty feet is the sensible length here: a 50 amp cord is heavy, and every extra foot is weight in a bay you were already short of.
3. Best Value: PlugSaf 50 FT 30 Amp RV Extension Cord (10AWG STW)
PlugSaf 50 FT 30 Amp RV Extension Cord (10AWG STW)
PlugSaf
- Same 10 AWG gauge as the Camco
- STW-rated jacket for outdoor use
- 50 feet, 125V 3750W
- Lighted end confirms live power
- 4.8★ from 886 owners
Why we picked it: The specification that matters most on a shore cord is conductor gauge, and this one does not cut that corner — it is the same 10 AWG as the Camco, in an STW outdoor-rated jacket, for noticeably less. The lighted end is a small convenience that saves a trip back to the pedestal to find out whether the breaker is on. It has a smaller owner base than the Camco cords, which is the only reason it is the value pick rather than the outright one.

What to Look For
Gauge is the spec that matters. A 30 amp cord should be 10 AWG copper; 50 amp cords are heavier still. Undersized conductors drop voltage over the run and get warm, and low voltage is what damages air conditioners and converters. Never judge a shore cord by its jacket.
Buy the length you will actually need. Pedestal placement is unpredictable, and chaining two cords or stacking adapters adds resistance at every connection. Fifty feet for 30 amp and thirty feet for 50 amp covers most sites; carrying one good long cord beats carrying two short ones.
Grip handles and moulded ends. You will unplug this cord wet, cold, and in the dark. Moulded strain relief and a real handle prevent the tugging that eventually pulls conductors loose inside the plug — the most common way a shore cord fails.
Match the cord to your rig, not the pedestal. Your RV's inlet decides whether you need 30 or 50 amp. Adapters let you plug a 30 amp rig into a 50 amp pedestal and vice versa, but the cord itself should match the rig's service, and a 50 amp rig on a 30 amp supply is limited to 30 amps of draw.
Bottom Line: Which Should You Buy?
For most people: the Camco PowerGrip 30A 50ft. Best for most 30A rigs.
Best value: the Camco Power Grip 50A 30ft. Best for 50A rigs.
Also consider: the PlugSaf 30A 50ft. Best value 30A cord.

Frequently Asked Questions
What size power cord do I need for my RV?
Match the cord to your RV's shore power inlet: a 30 amp rig uses a three-prong TT-30 cord in 10 AWG, a 50 amp rig uses a four-prong 14-50 cord in heavier gauge. The pedestal you plug into does not change what the rig needs.
Can I use a regular extension cord for my RV?
No. Household extension cords are not rated for the sustained current an RV draws and will overheat. Use a cord built and rated for RV shore power, in the correct gauge for your service.
How long can an RV extension cord be?
Fifty feet is the practical maximum for 30 amp without meaningful voltage drop, and thirty feet is typical for 50 amp because the cable is so heavy. Longer runs need heavier gauge, not just more cord.
Do I need an adapter for my RV power cord?
Often, yes. A 30-to-50 or 50-to-30 amp "dogbone" adapter lets you use whatever pedestal the site has. Keep both in the bay — but remember that adapting a 50 amp rig down to 30 amps limits what you can run at once.
Why is my RV power cord getting hot?
Usually undersized cable, a loose or corroded connection, or too many adapters stacked together. A warm cord is a warning, not a quirk — check the plug ends for discolouration and stop using it if you find any.

How We Research
Picks are based on manufacturer specifications, current Amazon availability, and patterns across verified owner reviews. Specs, capacities, and included accessories vary by listing — confirm the current details at the retailer before buying.
Note: Check the plug ends for heat discolouration or pitting each season, avoid stacking adapters, and never run a shore cord coiled on the reel under full load — coiled cable cannot shed heat.
