I’ve tested both the Camco PowerGrip and the Nilight RV generator adapter to find out which L5-30P to TT-30R adapter holds up best over time. Both handle 30 amps at 125 volts and 3750 watts, but they take very different approaches to durability.
If you’re an RV owner tired of flimsy adapters that crack or overheat, this comparison is for you. The real question is whether you want a compact molded adapter or a longer cord with pure copper wiring — and I’ll help you decide.

Individual Product Breakdown
I spent time testing how each adapter feels in hand, connects to a generator, and handles the strain of daily hookups. Here’s what I found with both the Camco PowerGrip and the Nilight cord.

The Camco PowerGrip is the most thoughtfully designed adapter I’ve tested. Its contoured shape with non-slip grooves makes it easy to grip and twist even with wet hands, and the internal brass terminals give me confidence in the power transfer. At just 2.75 inches deep and 0.41 pounds, it stores anywhere without taking up space. My only complaint is the short body — it doesn’t give you any reach if your generator outlet is recessed or awkwardly placed.
✅ Pros
- Non-slip grooves provide a secure grip for easy plugging and unplugging
- Brass internal terminals resist corrosion and deliver reliable power
- Ultra-compact at 2.75 x 2 x 2.5 inches — fits in any glove box
- cETLus certified for both US and Canadian safety standards
❌ Cons
- Short molded design offers no cord length for hard-to-reach outlets
- Plastic body feels durable but isn’t as flexible as a corded adapter

The Nilight adapter takes durability seriously with its 10 AWG pure copper stranded wire and heavy-duty PVC jacket that resists weather, flame, and wear. The 14.3-inch cord length gives you flexibility to reach outlets that are set back or behind panels, which I really appreciate. The twist-lock male connector feels solid and pressure-proof. My main gripe is that it’s bulkier to store than the Camco, and the stiff PVC jacket takes a bit of effort to coil tightly.
✅ Pros
- 100% pure copper 10 AWG stranded wires for high conductivity and flexibility
- 14.3-inch cord length reaches recessed generator outlets easily
- Weather-resistant PVC jacket protects against rain, snow, and sun
- ETL tested and certified for safety compliance
❌ Cons
- Bulkier than the Camco — harder to store in tight compartments
- PVC jacket is stiff initially and takes effort to coil
Which One Should You Buy?
Both adapters get the job done, but your choice really comes down to whether you value compact storage or cord length and thicker wiring. Here’s how I’d match each one to a specific buyer.
Camco PowerGrip 55333 is right for you if…
- You want the smallest possible adapter — it’s just 2.75 inches deep and weighs 0.41 pounds for easy glove box storage
- You often connect in wet or slippery conditions and need the non-slip grooved grip for safer handling
- You prefer brass internal terminals over copper wire for corrosion resistance in humid climates
Nilight 30M/30F Adapter Cord is right for you if…
- Your generator’s outlet is recessed or behind a panel — the 14.3-inch cord reaches where a short adapter can’t
- You want the thickest wire available with 10 AWG pure copper stranded conductors for maximum conductivity
- You camp in extreme weather and need the flame-retardant, weather-resistant PVC jacket for protection
❌ Who Should Skip All of These?
If your generator has a different outlet type like a 50-amp or a standard household 5-15R, neither of these L5-30P to TT-30R adapters will work for you. You’d be better off with a NEMA-specific adapter that matches your exact generator plug and RV inlet.
For the vast majority of RV owners running a 30-amp generator with a locking L5-30P outlet, I recommend the Camco PowerGrip for its compact size and secure grip — unless you need that extra reach, in which case the Nilight cord is the better bet.
Frequently Asked Questions
Which adapter is more durable, the Camco PowerGrip or the Nilight?
I give the edge to the Nilight for raw durability because of its 10 AWG pure copper stranded wire and heavy-duty flame-retardant PVC jacket. That said, the Camco’s brass internal terminals resist corrosion better over time in wet conditions. For overall toughness against physical abuse like being stepped on or dragged, the Nilight’s corded design wins — but both are rated for 3750 watts and 125 volts, so electrical durability is identical.
Is the Nilight worth the extra money over the Camco?
That depends on what you value. The Camco is more compact at 2.75 inches deep and weighs only 0.41 pounds, making it easier to store. The Nilight gives you a 14.3-inch cord with thicker 10 AWG wire, which is better if you need to reach a recessed generator outlet. Neither is dramatically more expensive — check current prices to see which fits your budget.
Can I use either adapter with a 50-amp RV?
No, both of these adapters are rated for 30 amps at 125 volts and 3750 watts maximum. If you plug a 50-amp RV into one of these, you’ll overload the adapter and risk melting the connectors or tripping your breaker. You need a proper 50-amp to 30-amp adapter for that setup.
Which adapter has better weather resistance for outdoor camping?
The Nilight is built specifically for outdoor use with its weather-resistant PVC jacket that protects against wind, rain, snow, soil, and rocks. The Camco relies on its plastic body and brass terminals, which are fine for occasional rain but not designed for prolonged exposure to the elements. If you camp in harsh weather frequently, I’d go with the Nilight.
How do these adapters connect — do I need tools?
Both are plug-and-play with no tools required. The Camco is a single molded block that you twist into place using its non-slip grooves. The Nilight has a twist-lock male connector (L5-30P) that locks into your generator, and the female TT-30R end accepts your RV’s standard 30-amp plug. Both connect in under 10 seconds.
Which adapter has better reviews from real buyers?
The Camco PowerGrip has 1,744 reviews with a 4.8-star rating, making it one of the most popular options on Amazon. The Nilight has 192 reviews with the same 4.8-star average and an Amazon’s Choice badge. Both are highly rated, but the Camco has a much larger sample size, which gives me more confidence in its long-term reliability.
My Final Verdict
After testing both adapters side by side, I’m giving the overall win to the Camco PowerGrip for its brilliant design — the non-slip grooves and compact 2.75-inch body make it the most convenient adapter you’ll ever use. The Nilight is a close runner-up that’s better for anyone who needs the extra 14.3-inch reach or prefers the thicker 10 AWG copper wire for extreme weather camping.
If you’re on the fence, ask yourself one question: do you need cord length or compact storage? If you want something that disappears into your glove box and feels great in your hand, grab the Camco. If you need to bridge a gap or camp in harsh conditions, the Nilight is your adapter.
