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
SureCall Flare 3.0 Home Cell Signal Booster
Pros
- Strong value for larger indoor coverage
- All-carrier support
- Good command-post option for a family or condo floor
- Often costs less than comparable weBoost coverage
- Useful when the best signal is near one exterior wall
Cons
- Outdoor antenna placement matters
- Not the cleanest no-drill renter setup
- Wireless-provider registration and E911 caveats still apply
- Support and documentation can feel less polished
- Coverage claims shrink quickly in dense buildings
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.
SureCall Flare 3.0 Home Cell Signal Booster
The Flare 3.0 is the value play when you have permission to install a real antenna path. For renters without that permission, start with a smaller one-room plan first.
