Pros & Cons
Earth Pak Original Waterproof Dry Bag 20L, Roll-Top Closure, 500D PVC, IPX5
Pros
- 500D PVC construction is genuinely rugged and flood-resistant
- Roll-top closure is foolproof and requires no zippers to fail
- IPX5 rated — handles high-pressure water spray from any angle
- Floats if submerged briefly (5–10 sec)
- Under $30 — low-cost insurance for expensive electronics
Cons
- Not rated for sustained submersion — not for diving or flooding scenario where kit is underwater for minutes
- 20L is adequate but not large enough for full kit in one bag
EcoFlow RIVER 2 Portable Power Station (256Wh)
Pros
- 0–100% charge in 60 minutes via AC — fastest in class for sub-300Wh stations
- 256Wh LFP battery rated for 3,000+ cycles (~10 years daily use)
- 300W AC output handles most consumer electronics including radio chargers and small appliances
- Lightweight at 7.7 lbs — 30% lighter than comparable stations
- 5 charging inputs: AC, car 12V, solar, USB-C, generator — flexible off-grid recharge
Cons
- 256Wh capacity is modest — Starlink Mini at ~30W idle drains it in ~8 hours continuous
- 300W AC output excludes high-draw appliances (AC units, microwaves)
- No built-in waterproofing — needs protection from rain in open van/truck-bed use
- Currently shows as sold-out on EcoFlow's own shop; Amazon availability varies
Our Verdicts
Earth Pak Original Waterproof Dry Bag 20L, Roll-Top Closure, 500D PVC, IPX5
At under $30, the Earth Pak 20L is the most cost-effective way to protect phones, documents, radios, and chargers from hurricane storm surge and driving rain. The 500D PVC and roll-top closure handle IPX5 conditions reliably; just don't expect it to survive full submersion for more than a few seconds. Buy two and seal the electronics separately.
EcoFlow RIVER 2 Portable Power Station (256Wh)
The EcoFlow RIVER 2 hits the sweet spot for RV kit builds — compact, lightweight, LFP chemistry for longevity, and fast enough to top off overnight. At 256Wh it comfortably runs the MXT575 radio plus phones and a hotspot all day; pair with a 110W solar panel for indefinite off-grid operation. Specifically recommended as the power source for running Starlink Mini off-grid.
