Pros & Cons
Anker 40W Dual USB-C Car Charger with Power Delivery (PowerIQ 3.0)
Pros
- Dual USB-C with PowerIQ 3.0 — fast-charges any modern phone simultaneously on both ports
- Compact 12V plug keeps the dash uncluttered; stable fit in cigarette lighter port
- 40W split across 2 ports handles radio mic charge + phone at the same time
- Works in 12V and 24V vehicles (RV house circuits, trucks, vans)
- Under $20 — best price-to-performance for a rig charging hub
Cons
- Only 2 ports — larger RV builds with 4+ devices need a separate USB hub or powered strip
- No USB-A port — legacy devices need USB-A to USB-C adapter
- No 12V pass-through socket — can't power accessories that need the lighter port itself
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
Our Verdicts
Anker 40W Dual USB-C Car Charger with Power Delivery (PowerIQ 3.0)
The Anker PowerDrive III Duo is the no-brainer 12V charging hub for any RV or van kit — dual fast-charge USB-C ports, sub-$20 price, and Anker reliability make it the default 'keep everything topped off while driving' piece. For rigs with 4+ devices, pair with a second unit or step up to a powered USB hub mounted to the dash.
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.
