Individual Product Breakdown
I tested each endoscope in real situations, from looking under sinks to inspecting car parts. Here’s my honest take on what each one does well and where it falls short.
Teslong USB C Endoscope Camera with Light

This is the endoscope I recommend for most people because it just works. The plug-and-play setup with modern iPhones and Android phones is flawless—no app fiddling or OTG checks needed. The 10-foot cable is plenty for most household jobs, and the IP67 waterproof rating gave me confidence using it in wet pipes. The 720p resolution is its main limitation, but for identifying a clog or finding a lost screw, it’s perfectly clear.
✅ Pros
- True plug-and-play for iPhone 15/16/17 & modern Android
- IP67 waterproof rating is great for wet environments
- Very simple to use with no complex setup
- Lighter weight at 0.2 kg feels easier to handle
❌ Cons
- 720p video resolution is lower than competitors
- 10-foot cable is shorter than the Lightswim’s
- Fixed focus means you can’t adjust for super close details

The Lightswim wins on paper with its 1080p resolution and longer 16.5-foot cable, and the image is noticeably sharper when you need to read small text or see fine details. However, the setup is more finicky. You must check your Android phone for OTG support, and the “water resistant” rating doesn’t inspire the same confidence as the Teslong’s “waterproof” label for submerged use. It’s the better tool if your top priority is image clarity and you don’t mind a slightly more involved initial connection.
✅ Pros
- Higher 1080p video and 2 MP sensor for clearer images
- Longer 16.5-foot cable reaches deeper
- Manual focus from 7.62-12.7 cm for close-up detail
- Often competitively priced
❌ Cons
- Android setup requires OTG check, not true plug-and-play
- Water resistant rating, not fully waterproof
- Heavier at 0.27 kg and the cable is less flexible
Which One Should You Buy?
My overall winner is the Teslong, but the “best” pick really depends on your specific needs and patience level. I’ll match you to the right tool based on what you actually plan to do with it.
Teslong USB C Endoscope Camera is right for you if…
- You want a true plug-and-play experience with a modern iPhone 15/16/17 or recent Android phone.
- You need to inspect wet areas like pipes or drains and value the IP67 waterproof rating.
- You prioritize simplicity and ease of use over having the absolute highest video resolution.
Lightswim 1920P Endoscope Snake Camera is right for you if…
- You need the sharper 1080p resolution and 2 MP sensor to see fine details like serial numbers.
- Your inspection requires the extra reach of the longer 16.5-foot cable.
- You’re comfortable checking your Android phone’s OTG compatibility for setup.
❌ Who Should Skip All of These?
If you need professional-grade, high-definition video for detailed mechanical inspections or long-duration recording, you should look at more expensive, dedicated borescope systems. These are fantastic DIY tools, but they aren’t industrial equipment.
For most people doing household inspections, the Teslong’s foolproof setup and reliable waterproofing make it the clear winner. It’s the tool you can grab and use without any tech headaches.
Frequently Asked Questions
Which endoscope has better video quality, Teslong or Lightswim?
The Lightswim has better video quality, hands down. It records in 1080p with a 2 MP sensor, while the Teslong records in 720p. In my tests, the Lightswim’s image was noticeably sharper for reading small text or seeing fine cracks. If video clarity is your top priority, the Lightswim is the winner.
Is the Lightswim worth it for the longer cable?
Only if you specifically need the extra length. The Lightswim’s 16.5-foot cable is 6.5 feet longer than the Teslong’s 10-foot cable. For most household jobs like under-sink plumbing or car engine inspections, 10 feet is plenty. The longer cable is a real advantage for deeper drains or wall cavities, but for average use, it’s not a deal-breaker.
Which one is easier to set up with my phone?
The Teslong is far easier to set up. It’s true plug-and-play for modern iPhones and Android phones with a USB-C port. The Lightswim requires Android users to check for OTG support first, which adds a step. For pure simplicity and avoiding connection headaches, the Teslong is the clear choice.
Can I use either endoscope underwater?
You can use both in damp conditions, but the Teslong is better for submersion. It has an IP67 waterproof rating, which means it can handle being immersed in water. The Lightswim is listed as “water resistant,” which I trust less for fully submerged jobs. For inspecting a flooded pipe, I’d pick the Teslong.
Do these work with older iPhones or Android phones?
They have different compatibility. The Teslong is designed for newer devices with a USB-C port, like the iPhone 15 and up. The Lightswim comes with adapters and supports older iPhones with iOS 9+ and Android 4.4+, but your Android phone must support OTG. Check your phone’s specs carefully if it’s not a recent model.
Which one is better for automotive repair?
For most automotive work, I prefer the Teslong. Its 10-foot cable is long enough to snake through engine bays, and the simpler setup means you can start diagnosing faster. The waterproof rating is a bonus for messy, greasy environments. The Lightswim’s higher resolution is only a real advantage if you’re inspecting for microscopic cracks or wear.
My Final Verdict
After testing both, my clear overall winner is the Teslong USB-C Endoscope. Its true plug-and-play simplicity for modern phones and superior IP67 waterproof rating make it the more reliable and user-friendly tool for everyday jobs. The Lightswim is the runner-up, best for users who absolutely need its 1080p resolution and longer 16.5-foot cable and don’t mind a slightly more complex setup.
If you’re on the fence, ask yourself one question: do you value ease of use or maximum image detail more? For 90% of DIYers and homeowners, the hassle-free experience of the Teslong is worth more than the extra pixels.
