📋 目次
1What level of waterproofing should I look for in a laptop briefcase?
Look for IP65 to IP67 ratings for reliable protection against rain, splashes, and brief submersion. IP67 means the case can survive immersion in up to 1 meter of water for 30 minutes, which is ideal for travel or unpredictable weather.
2How much padding do I need to protect my laptop?
A minimum of 10-15mm of high-density foam padding is recommended for laptops up to 16 inches. Thicker padding (20mm+) is better for heavier or more valuable devices, especially if you plan to carry the briefcase in rough conditions.
3Are all waterproof briefcases also dustproof?
Not always — while many waterproof cases are also dustproof (IP6X rating), check the full IP rating. IP65 to IP67 covers dust and water, but lower ratings like IP54 only offer partial dust and water resistance, which may not be enough for extreme environments.
4What size laptop fits in a typical waterproof briefcase?
Most waterproof briefcases fit 13-16 inch laptops, with some models going up to 17 inches. Measure your laptop’s dimensions and add 1-2cm for padding and ease of insertion. Compact models may only fit 13-inch devices, so check the internal dimensions carefully.
5Is a USB port or charging slot worth the extra cost?
A built-in USB port or charging slot is convenient for on-the-go charging, but it can compromise waterproof integrity if not sealed properly. Look for magnetic or sealed ports with rubber covers to maintain protection without added hassle.
