9. BLAVOR Solar Power Bank – Best Solar Charging Option

The BLAVOR Solar Power Bank combines solar charging with wireless charging for maximum versatility.

During a camping trip, I found the solar panel useful for maintaining charge when outlet access was limited for several days.

Be realistic: solar charging alone will not quickly recharge the power bank, but it helps extend battery life during extended outdoor trips.

The 10,000mAh capacity provides 2-3 phone charges, and the IP67 rating protects against water and dust.

Wireless charging is convenient but slower than wired charging, so use it when speed is not critical.

Who Should Buy?

Off-grid campers and outdoor adventurers who need backup charging options when traditional power sources are unavailable.

Who Should Avoid?

Urban travelers or anyone with reliable access to outlets should choose a non-solar model for better value.

10. Solar 38,800mAh Power Bank – Highest Capacity Solar Option

This 38,800mAh solar power bank offers the highest capacity in this review with four solar panels for faster solar charging.

The four-panel design captures significantly more solar energy than single-panel alternatives, making it practical for extended off-grid use.

The IP67 rating provides protection against rain and temporary water submersion during outdoor activities.

Be aware that 38,800mAh exceeds 100Wh, so this power bank may not be allowed on commercial flights.

Who Should Buy?

Extended campers and outdoor adventurers who need maximum capacity and solar charging for off-grid trips lasting several days.

Who Should Avoid?

Airline travelers should choose a lower-capacity model that complies with flight regulations.

Why Waterproof Power Banks Matter for Travel?

A waterproof power bank is a portable charger with sealed construction and an IP67 or IP68 rating that protects against water immersion, making it ideal for travel, outdoor activities, and wet environments.

Regular power banks fail quickly when exposed to water due to unprotected charging ports and non-sealed casings.

Waterproof power banks use sealed casings, rubber gaskets, and covered ports to prevent water from entering the internal battery and electronics.

After my experience in Thailand, I have learned that investing in waterproof protection is cheaper than replacing a ruined power bank and dealing with a dead battery in an unfamiliar place.

How to Choose the Best Waterproof Power Bank for Travel?

Choosing the right waterproof power bank depends on your travel style, destinations, and charging needs.

Here are the key factors I recommend considering based on my testing experience:

Solving for Waterproof Protection: Look for IP67 or IP68 Rating

The IP rating tells you exactly how much water exposure the power bank can handle.

IP67 means the device can survive immersion in 1 meter of water for 30 minutes, which covers most accidental drops in water.

IP68 offers even better protection with deeper and longer submersion capabilities specified by the manufacturer.

For beach travel, boating, or heavy rain environments, I recommend IP68 for maximum protection.

For light rain and splash protection, IP67 is usually sufficient and often costs less.

Solving for Capacity: Match mAh to Your Travel Style

Capacity determines how many times you can charge your devices before the power bank itself needs recharging.

• 5,000-10,000mAh: 1-3 phone charges. Best for day trips and short getaways.
• 15,000-20,000mAh: 4-7 phone charges. Ideal for weekend trips and camping.
• 30,000mAh+: 8+ phone charges or laptop charging. Best for extended travel and workations.

For international travel, I recommend 15,000-20,000mAh as a sweet spot between capacity and portability.

Solving for Charging Speed: Look for USB-C Power Delivery

Charging speed determines how fast your devices recharge from the power bank.

USB-C Power Delivery (PD) is the modern standard for fast charging and is essential for tablets and laptops.

• 15-18W: Good for smartphones
• 20-30W: Better for fast phone charging and small tablets
• 45W+: Required for laptop charging

For phone-only charging, 18-20W is sufficient. If you need to charge laptops or tablets, look for 30W+ output.

Solving for Airline Travel: Check Capacity Limits

Not all power banks are allowed on airplanes due to fire safety regulations.

To calculate watt-hours: divide mAh by 1000, then multiply by voltage (usually 3.7V).

Example: 20,000mAh divided by 1000 equals 20, times 3.7V equals 74Wh.

Solving for Durability: Consider Shockproof and Dustproof Ratings

Travel involves more than just water exposure.

Look for shockproof or drop-resistant designs if you plan outdoor activities or rugged travel.

Dustproof protection (indicated by the first digit in IP ratings) matters for desert travel, beach trips, and hiking.

Rubberized coatings and textured grips help maintain hold on the power bank with wet or sweaty hands.
