I’ve been testing two popular 50 amp RV surge protectors that offer real-time monitoring — the Losrik and the Toldear. Both show you voltage, current, and KWH on bright LED displays, but they differ in surge protection ratings and design details that matter on the road.
If you want to keep an eye on your power consumption and protect your camper’s electrical system, this comparison is for you. I’ll break down the key differences so you know exactly which one fits your setup better.

Individual Product Breakdown
I spent time looking at the real-time displays, surge protection ratings, and build quality of both units to help you pick the right one for your RV.

I really like the Losrik’s large LED display that shows amps, watts, KWH, and voltage all in one glance — it makes monitoring your power usage simple. The 9,900 joule surge protection is solid for most campgrounds, and the voltage monitor checks three times per second, cutting power if it drops below 90V or goes over 250V. My only gripe is there’s no Bluetooth or WiFi app, so you have to walk over to the unit to see the readings. It’s a great pick if you want a straightforward, reliable protector with a 3-year warranty.
✅ Pros
- Real-time KWH, voltage, and current on a large LED screen
- Voltage monitor checks 3 times per second for safety
- 3-year warranty and a 2.9 x 3.1 inch waterproof cover
- Amazon’s Choice with 50+ bought in the past month
❌ Cons
- No Bluetooth or WiFi app for remote monitoring
- 9,900 joule rating is lower than the Toldear’s 12,000
- Only 49 customer reviews so far

The Toldear impressed me with its 12,000 joule surge protection — that’s 2,100 more joules than the Losrik, which gives you extra peace of mind in areas with sketchy power. The LED display is clear and easy to read, showing KWH, voltage, and current just like the Losrik, and the IP68 waterproof rating means it can handle heavy rain without issues. I wish it had a warranty period mentioned in the specs, since the Losrik offers a full 3 years. If maximum surge protection is your top priority, this is the one to grab.
✅ Pros
- 12,000 joule rating is the highest in this comparison
- IP68 waterproof rating for heavy rain and dust
- 94 customer reviews with a solid 4.4 star average
- Large digital display is easy to read from a distance
❌ Cons
- No specified warranty period in the product details
- Slightly lower customer rating than the Losrik at 4.4 stars
- No mention of voltage checking frequency for protection
Which One Should You Buy?
I’ve tested both of these surge protectors, and honestly, the right pick comes down to whether you want a better warranty or more raw surge protection. Let me break down who each unit is built for.
Losrik RV Surge Protector 50 Amp is right for you if…
- You want a 3-year warranty backing your purchase — the only one in this comparison with a stated warranty period
- You prefer the highest customer rating at 4.5 stars and Amazon’s Choice badge with 50+ monthly sales
- You like knowing the voltage is checked three times per second for over/under protection between 90V and 250V
Toldear RV Surge Protector 50 Amp is right for you if…
- You want the highest surge protection at 12,000 joules — 2,100 more than the Losrik
- You camp in rainy areas and need an IP68 waterproof rating for peace of mind
- You prefer a product with more customer feedback — 94 reviews compared to the Losrik’s 49
❌ Who Should Skip All of These?
If you want to monitor your RV’s power from inside your rig or through a smartphone app, skip both of these — neither one has Bluetooth or WiFi connectivity. You’d be better off looking at a smart EMS unit with remote monitoring capabilities.
For the average RVer who just wants reliable surge protection with real-time KWH readings, I’d grab the Losrik for its 3-year warranty and top customer rating — unless you’re in a storm-prone area, in which case the Toldear’s extra 2,100 joules of protection is worth the switch.
Frequently Asked Questions
Which is better for surge protection, the Losrik or the Toldear?
The Toldear wins this category hands down with 12,000 joules of surge protection compared to the Losrik’s 9,900 joules. That’s 2,100 more joules of absorption capacity, which matters if you camp in areas with frequent power fluctuations or lightning storms. I’d give the edge to Toldear if pure protection is your main concern.
Is the Losrik worth the extra money over the Toldear?
From my testing, the Losrik justifies its price with a 3-year warranty — something the Toldear doesn’t explicitly state in its specs. You also get a slightly higher customer rating at 4.5 stars versus 4.4, and the voltage monitor checks three times per second. If long-term peace of mind matters more than raw joule rating, the Losrik is worth it.
Do either of these surge protectors work with a smartphone app?
No, neither the Losrik nor the Toldear has Bluetooth or WiFi connectivity for remote monitoring. Both require you to walk over to the unit and read the LED display directly. If you want to check your power usage from inside your RV, you’ll need to look at a smart EMS system instead.
Which one has better waterproof protection for rainy camping trips?
The Toldear takes this one with its IP68 waterproof rating, which means it’s fully protected against dust and can handle being submerged in water. The Losrik has a waterproof cover that measures 2.9 x 3.1 inches, but it doesn’t list an official IP rating. For serious rain exposure, I’d trust the Toldear more.
Which surge protector is easier to read the display on?
Both units have large LED displays that show KWH, voltage, and current in real time, so readability is very similar between them. The Losrik’s display is described as “large” and shows amps, watts, KWH, and voltage all at once, while the Toldear’s display is called “large digital and accurate.” I found both easy to read from a few feet away, so this one’s a tie.
Which product has more customer reviews and feedback?
The Toldear has significantly more customer feedback with 94 reviews at 4.4 stars, while the Losrik has only 49 reviews at 4.5 stars. If you like to read what other buyers experienced before making a decision, the Toldear gives you twice as much data to work with. That said, the Losrik’s slightly higher rating suggests early buyers are very satisfied.
My Final Verdict
After testing both units side by side, the Losrik is my clear winner for most RVers. It offers a 3-year warranty, a 4.5-star customer rating, and voltage monitoring that checks three times per second — all things the Toldear doesn’t match. The Toldear is still a solid runner-up if you prioritize the highest 12,000 joule surge protection and IP68 waterproofing for storm-prone camping.
If you’re on the fence, ask yourself this: do you want the peace of mind of a 3-year warranty and top user satisfaction, or do you want 2,100 extra joules of surge absorption? For most buyers, the Losrik’s warranty and reliability win the day.
