Frequently Asked Questions

Which has better surge protection, the GEARGO or the CARMTEK?

The GEARGO wins this one hands down with 15000 joules of surge protection compared to the CARMTEK’s 4200 joules. That’s over three times the energy absorption capacity, which means the GEARGO can handle bigger power spikes from lightning strikes or grid issues. For most RVers, the CARMTEK’s 4200 joules is adequate for everyday surges, but if you camp in storm-prone areas, I’d go with the GEARGO for the extra headroom.

Is the CARMTEK worth paying more than the GEARGO?

In my testing, I don’t think the CARMTEK justifies its higher price unless you specifically need UL certification or the extra wiring fault detection. The GEARGO offers more than triple the joules, an IP68 waterproof rating, and a 3-year warranty for less money. The CARMTEK’s main advantages are its UL testing and ergonomic grip handles, but for raw protection and durability, the GEARGO is the better value.

Which surge protector is more waterproof and weather-resistant?

The GEARGO is clearly the winner here with its IP68 waterproof rating, which means it’s fully protected against dust and can handle continuous immersion in water. The CARMTEK is described as weather resistant and thermally protected, but it doesn’t list a specific IP rating in the specs. If you regularly camp in heavy rain or near the coast, I’d trust the GEARGO to hold up better over time.

Which one detects more wiring faults, the GEARGO or CARMTEK?

The CARMTEK actually detects more fault conditions than the GEARGO. The CARMTEK checks for 9 different wiring faults including L1-Open, L2-Open, L1-Neutral Reversed, and L2-Ground Reversed. The GEARGO only checks for 6 faults: correct wiring, open ground, open neutral, reverse polarity, reverse heat/ground, and no power. If you’re dealing with a tricky pedestal at an older campground, the CARMTEK gives you more diagnostic info.

Which one is easier to plug and unplug from the RV pedestal?

The CARMTEK is noticeably easier to handle thanks to its ergonomic power grip handles that let you get a solid hold on the unit. The GEARGO uses a right-angle male plug but doesn’t have the same built-in grip design. If you have arthritis or limited hand strength, or if you’re constantly plugging in at tight campsites, the CARMTEK’s handles make a real difference.

How many reviews does each product have and which is more trusted?

The CARMTEK has over 1,546 reviews with a 4.8-star rating, making it the more established product with a longer track record. The GEARGO has 465 reviews but also holds a 4.8-star rating and carries an Amazon’s Choice badge. Both are highly rated, but the CARMTEK’s larger review count gives it an edge in proven reliability over time.
