Understanding IP Ratings: Is Your Gear Actually Waterproof?

Tech - by Joe Weber - updated on 1/9/2026

You just bought a rugged Streamlight flashlight, a new X2Power marine battery charger, or an outdoor security camera. The box proudly claims it is "IP67 Rated." But if you drop that flashlight in the lake or leave the camera out in a storm, will it actually survive?

At Batteries Plus, we know that marketing terms like "waterproof" and "weather-resistant" can be confusing. To really protect your investment, you need to look past the buzzwords and understand the IP Rating. Whether you are outfitting your boat, securing your home, or just looking for a durable work light, this rating is the only objective way to know if your gear is built for the job.

What is an IP Rating?

IP stands for Ingress Protection. It is an international standard used to define how effectively an electrical enclosure seals out foreign bodies and moisture.

Basically, an IP rating gives you a concrete score on two fronts:

1. Solids: How well it keeps out dust, dirt, and debris (crucial for workshop tools).
2. Liquids: How well it keeps out water (crucial for marine and outdoor gear).

Breaking Down the Digits

An IP rating typically consists of two numbers (e.g., IP65). Each digit has a specific meaning.

The First Digit: Solid Object Protection

This number ranges from 0 to 6. It indicates protection against hazardous parts and solid foreign objects.

• 0: No protection.
• 5: Dust protected (Some dust may enter, but not enough to interfere with operation).
• 6: Dust-tight (Complete protection against contact).

The Second Digit: Liquid Protection

This number ranges from 0 to 9. It indicates protection against water ingress.

• 0: No protection.
• 4: Protected against splashes (Rain/Sweat).
• 7: Protected against temporary immersion (Dropped in a sink).
• 8: Protected against continuous immersion (Underwater use).

Chart of Possible IP Ratings

Here is a breakdown of what each digit represents so you can decode the specs on your next purchase.

First Digit (Solids)	Protection Level	Second Digit (Liquids)	Protection Level
0	No protection	0	No protection
1	Objects >50mm (e.g., hands)	1	Vertically dripping water
2	Objects >12mm (e.g., fingers)	2	Dripping water (tilted 15°)
3	Objects >2.5mm (e.g., tools)	3	Spraying water
4	Objects >1mm (e.g., wires)	4	Splashing water
5	Dust protected (limited entry)	5	Water jets (nozzle)
6	Dust-tight (no entry)	6	Powerful water jets
		7	Immersion up to 1m (30 mins)
		8	Immersion beyond 1m
		9	High-temp/High-pressure jets

Common IP Ratings Explained

When shopping for electronics, you will likely encounter these specific ratings:

• IPX4 (Sweat/Splash Proof):
  • Common in: Workout headphones, basic Bluetooth speakers.
  • The Verdict: Fine for a sweaty run or a light drizzle, but do not drop it in the bathtub.
• IP65 (Weatherproof):
  • Common in: Outdoor security cameras, porch lights, and industrial equipment.
  • The Verdict: It is dust-tight and can handle rain or being sprayed with a garden hose, but it cannot be submerged underwater.
• IP67 (Immersion Resistant):
  • Common in: Modern smartphones, rugged portable speakers.
  • The Verdict: Can survive being dropped in a toilet or a shallow pool (up to 1 meter deep) for 30 minutes. It is dust-tight.
• IP68 (Waterproof):
  • Common in: Flagship smartphones, dive watches, and action cameras.
  • The Verdict: The gold standard for consumers. It is dust-tight and can generally be submerged deeper than 1 meter for longer periods (check the manufacturer's specific depth limit).

Why This Matters for Your Wallet

Ignoring IP ratings is one of the fastest ways to void a warranty. Many manufacturers will deny a repair claim if "water damage" is found, even if the device was marketed as "water-resistant."

By checking the IP specifications, you can ensure you are buying the right tool for the job. You don't need an IP68 rating for a TV that stays in your living room, but you absolutely need it for a smartwatch you plan to wear while swimming.

Caring for Your Waterproof (IP67+) Gear

Just because a device is rated IP67 or IP68 doesn't mean it is indestructible. To ensure your high-end waterproof flashlights and marine chargers continue to perform in harsh environments, regular maintenance goes a long way.

Maintaining Waterproof Flashlights:

• Rinse After Exposure: If you use your IP67 tactical light in saltwater or muddy conditions, don't just let it dry. Salt crystals can act like sandpaper on seals. Rinse the light thoroughly with fresh water.
• Lubricate the O-Rings: The rubber O-rings are the only thing standing between the water and your battery. Over time, these can dry out and crack. Check them periodically and apply a small amount of silicone grease to keep them supple and water-tight.
• Check the Lens: Ensure the bezel is screwed down tight before submersion. A loose bezel can compromise the seal around the lens.

Maintaining Marine & Outdoor Chargers:

• Inspect the Terminals: While the charger body may be sealed (IP67), the metal ring terminals or clamps usually aren't. Keep these clean and free of corrosion (green or white buildup) to ensure a strong connection.
• Watch for Cracks: An IP rating is void if the casing is damaged. Regularly inspect your onboard charger for cracks or deep gouges that could let moisture inside the sealed unit.

I Dropped My Phone in the Water! Now What?

Even with an IP68 rating, accidents happen. Seals dry out, screens crack, and water finds a way in. If your phone takes a plunge—whether it's an older model or the latest iPhone—you need to act fast to save it.

Immediate Steps to Save Your Phone:

1. Turn it Off Immediately: Do not try to use it, charge it, or check texts. Cut the power to prevent short circuits.
2. Strip it Down: Remove the case, screen protector (if water got under it), SIM card tray, and SD card. This opens up the ports and allows air to circulate.
3. Wipe and Tap: Dry the exterior with a lint-free cloth. Hold the phone with the charging port facing down and gently tap it against your hand to dislodge trapped water.
4. Air Dry (Skip the Rice): Place the phone in a dry, well-ventilated area. A cool fan blowing gently over it is the best method.

   Pro Tip: Do not put it in rice. Rice dust can clog your charging port and camera lenses, and it doesn't absorb water fast enough to help. Silica gel packets (like the ones in shoe boxes) are a much safer alternative if you have them.

5. Avoid Heat: Never use a hair dryer, oven, or microwave. High heat can damage the battery and melt internal adhesives.

The Next Step: Schedule a Free Diagnostic

You've dried it off, but is it safe to turn on? Turning a phone on while there is still moisture inside is the #1 cause of permanent death for electronics.

Frequently Asked Questions (FAQ)

Q: What does it mean if a rating has an 'X' (e.g., IPX7)?

A: The 'X' means the product was not tested for that specific category. IPX7 means the device is waterproof (level 7) but wasn't formally tested for dust resistance. It doesn't mean it offers zero dust protection, just that no data is claimed.

Q: Can I swim with an IP68 phone?

A: Usually, yes, but be careful. IP testing is done in fresh water in a lab. Saltwater (ocean) and chlorinated water (pools) can corrode seals over time. Always rinse your device with fresh water after swimming.

Q: Is IP68 better than IP67?

A: Yes. Both are dust-tight (indicated by the '6'), but the '8' indicates the device can handle deeper water or longer durations of submersion than the '7'.

Q: Does "Water Resistant" mean "Waterproof"?

A: No. "Water resistant" usually implies lower ratings (IPX4 or IPX5) meant for rain or splashes. "Waterproof" is a marketing term usually reserved for IP67 and IP68, implying the device can actually go underwater.
