Kohree RV Surge Protector 50 Amp — 20,000J Surge Protection, IP67 Weatherproof

Designed for RV owners and mobile-living enthusiasts, this Kohree 50A surge protector combines fast-acting surge absorption, voltage monitoring, and automatic disconnect/reconnect logic in a weatherproof enclosure. It reads incoming line voltage on a large LED screen, isolates the coach when voltage falls outside a safe 104–132V window, and restarts automatically once conditions normalize. The unit's rugged construction, ergonomic grips, and right-angle connector make it practical for frequent hookups and outdoor conditions.

How does this protector shield my RV from power surges and spikes?

The Kohree unit uses high-energy surge suppression rated at 20,000 joules and reactive circuitry that clamps voltage transients in nanoseconds. That rapid absorption reduces the chance of damage from lightning-induced spikes, switching events on utility lines, and other sudden voltage excursions.

• 20,000J surge absorption to mitigate high-energy transients.
• Sub-nanosecond response time to arrest spikes quickly.
• Flame-retardant housing and pure-copper contacts for reliable conduction.

What voltage conditions will make it cut power, and how does it restart?

The device continuously measures incoming voltage and uses a relay to disconnect power if it detects unsafe levels: below 104V or above 132V. When the feed returns to the safe range, the protector automatically reconnects so you don’t have to intervene at the pedestal.

• Under-voltage trip threshold at 104V to prevent brownouts from harming appliances.
• Over-voltage cutoff at 132V to stop excessive voltage reaching equipment.
• Automatic reconnection once voltage stabilizes—no manual reset required.

What information does the LED display show and why is it useful?

The large LED screen functions as a circuit analyzer, showing real-time input voltage and basic current status so you can quickly verify pedestal health. Quick visual checks help you decide whether to accept a shore power connection or wait for a different source.

• Real-time voltage readout to confirm pedestal stability before plugging in.
• Status indicators for connection, protection active, and faults.
• Helps diagnose poor shore power or long/thin feeder cable voltage drop issues.

Is this unit built to handle outdoor use and frequent plugging/unplugging?

Yes—the Kohree protector features an IP67-rated plug cover to keep rain and dust out, a heavy-duty right-angle male connector, and ergonomic grip handles to reduce strain on cords and connectors. The enclosure and components are selected to resist corrosion and reduce fire risk.

• IP67 waterproof plug cover protects against weather and debris.
• Right-angle connector reduces bending stress on pedestal inlets.
• Ergonomic grips and durable materials for easy, safe repeated use.

Who is this for? If you own an RV, camper, or travel trailer and want robust protection for appliances, electronics, and wiring when connected to campground shore power, this Kohree 50A surge protector is made for you. It is particularly valuable for frequent travelers, seasonal full-timers, or anyone who camps in areas prone to electrical instability. The combination of a high joule rating, automatic voltage disconnect/reconnect, clear LED diagnostics, and weatherproof construction gives peace of mind without complex installation.
