Do I really need waterproof cases if I'm staying in hotels with AC?

Yes. Hotels lose power, AC breaks, and you'll spend time outside where humidity hits 80-90%. Even brief exposure can cause long-term damage to electronics.

Can I use rice instead of silica gel packets?

Rice works for emergency phone drying but not prevention. Silica gel absorbs moisture more effectively and doesn't leave residue. Rice can actually attract insects in humid climates.

What about heat damage to electronics?

Heat is less damaging than humidity. Modern electronics handle 95°F+ temperatures fine. Focus your protection efforts on moisture, not temperature.

Should I pack backup electronics?

Pack backup charging cables and a basic phone at minimum. Don't pack backup laptops or cameras—proper moisture protection is more cost-effective than replacements.

How to Pack Electronics for Humid Asian Climates

Pack electronics in waterproof cases with silica gel packets, bring a portable dehumidifier, and use ziplock bags as backup protection. Focus on moisture prevention over heat protection—humidity is the real electronics killer in Southeast Asia.

Invest in waterproof cases. Buy hard waterproof cases for cameras, laptops, and tablets. Pelican cases work best but cost $50-150. Budget option: Seahorse cases at $25-80. Skip soft waterproof pouches—they fail in high humidity.
Pack silica gel packets everywhere. Buy 50-gram silica gel packets on Amazon ($15 for 30 packets). Put 2-3 packets in each electronics case or bag. Replace every 2 weeks in humid conditions. Dry used packets in an oven at 200°F for 2 hours.
Double-bag with ziplock. Put electronics in gallon-size ziplock bags with silica gel before placing in main cases. This creates two moisture barriers. Use freezer-grade bags—they're thicker and more reliable.
Bring a portable dehumidifier. Pack a small electric dehumidifier for your hotel room. Eva-Dry E-333 works well ($40, fits in carry-on). Run it overnight in closed spaces with your electronics to prevent moisture buildup.
Never leave electronics in bathrooms. Bathrooms in humid climates stay damp 24/7. Even closed cases can accumulate moisture. Keep everything in the main room, preferably near air conditioning.
Check weather sealing on existing gear. Test cameras and phones for weather sealing before you go. Most consumer electronics aren't truly waterproof despite marketing claims. Plan backup protection accordingly.
