Power Watchdog 40-Inch Security Cable Lock

The Power Watchdog lock is designed to deter theft of surge protectors and voltage boosters at campsites. It uses a heavy-duty braided stainless steel cable for strength and durability, and its 40-inch length provides flexible sealing to power pedestals or fixed structures. Best for RV owners who want a straightforward, rugged solution that fits a variety of mounting points. A potential limitation is the fixed length; if you need a longer reach, consider alternatives with extended cables.
scottchen PRO RV Surge Guard Lock (1 Pack)

Designed to protect the charging portion of the surge guard while the RV is plugged in, this lock uses a stainless steel rope wrapped in plastic for resilience and is compact for easy storage inside an RV. Best for RV owners who want a small, portable solution that’s simple to stow. A note: while durable, its compact size may limit securing options on very large pedestals.
Master Lock 8419DPF Python Cable Lock

The Master Lock Python Cable Lock is a versatile outdoor security cable with a key lock. It’s built with braided steel for strength and has a vinyl-coated cable to resist weather. Best for RVers who need a rugged, adaptable lock that can secure tools, bikes, or other outdoor equipment beyond the surge protector. It’s a practical all-around option, though it may be heavier than some compact models.
scottchen PRO RV Surge Guard Lock (2 Pack)

This 2-pack provides security for multiple surge protectors or devices in one RV, offering flexibility for larger setups. It uses a durable stainless steel rope with plastic wrapping for security and storage convenience. Best for RVs with more than one surge protector needing coverage. A limitation is that the set focuses on replacement cables, not always including the full locking head.
Camco 44290 Power Grip Cable with Security Lock

The Camco Power Grip Cable features a 60-inch, heavy-duty braided steel cord with a vinyl-coated lock head and a retractable key cover. Best for long runs between a pedestal and an RV, offering extended reach with weather-resistance. A caveat is that the longer length may require careful coil storage to prevent snagging when traveling.
Technology Research Southwire Surge Guard Lock Hasp

The Southwire Surge Guard Lock Hasp is designed to prevent unauthorized removal of Surge Guard devices from RVs. It easily attaches to standard 30 and 50-amp plugs. Best for RV owners who want a reliable, plug-specific lock that doesn’t require extra cables. It does not fit certain older Surge Guard models, so verify compatibility before purchase.
Buying Guide
- What length do you need? Longer cables offer flexibility but can complicate storage. Measure your typical pedestal distance and choose accordingly.
- What environment will you face? Look for weather-resistant coatings and vinyl or PVC coverings on the cable to withstand rain and sun.
- Are multiple devices secured? If you have more than one surge protector, consider a multi-pack or a locking system that supports several cables.
- Is theft deterrence enough, or do you want added security features? Some locks offer keyed access, while others rely on a higher-strength stainless steel rope.
- Portability versus permanence: Choose compact, easy-to-store options for frequent movers, or heavier, more robust cables for stationary setups.
FAQ
- Are surge protector locks universal? Most locks are designed to work with standard cables, but always verify compatibility with your specific surge protector model.
- Do locks affect warranty? Locking devices generally do not void warranties, but check the surge protector’s terms for any restrictions.
- What material lasts best at campsites? Braided stainless steel with weather-resistant coatings offers durable, long-lasting security.
- Can I secure multiple devices with one lock? Some products offer multi-pack options; others require separate cables for each device.
- Is a longer cable better? Longer cables increase reach but require careful storage to avoid tangling during travel.
- Should I rely on a lock alone? A lock secures physical access; always combine with situational awareness and park safety practices.
