Frequently Asked Questions
- Can LifeStraw filter out viruses? No. The 0.2‑micron membrane removes bacteria and parasites but not viruses. In high‑risk areas, pair it with chemical disinfection.
- How many times can a Mylar blanket be reused? The foil does not degrade with normal use; it can be unfolded, cleaned, and stored repeatedly.
- Is the Mini First Aid Kit waterproof enough for rainstorms? The EVA‑coated case is waterproof and will protect the contents from splashes and short submersion, but it should not be submerged for extended periods.
- Will Bactine MAX cause allergic reactions? The spray is latex‑free and formulated for children over two years. Users with lidocaine sensitivity should avoid it.
- How long does it take to fully charge the RunningSnail radio by hand? Approximately 2‑3 minutes of steady cranking generates enough power for several hours of radio operation; a full 2000 mAh charge requires about 20‑30 minutes of combined cranking and solar exposure.
- Can the radio charge a smartphone fully? Yes. The 2000 mAh battery can deliver roughly one full charge for most modern smartphones.
- Do the Mylar blankets work as a ground cover? Absolutely. Their reflective surface also repels moisture, making them suitable as a dry sleeping layer.
