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
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
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.
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.
