Starlink Mini vs Standard Gen3 for an RV, Van or Boat: Power Draw, Speed, Mounting, Cost and Which One to Buy
Sep 09, 2026
Most mobile buyers now choose between the Starlink Mini and the Standard Gen3 (the kickstand dish). They are different products with different install hardware, and the wrong choice shows up as a dead battery or a dish that will not fit. Here is the comparison from the install side.
Side by side
| Starlink Mini | Standard Gen3 | |
|---|---|---|
| Size and weight | 11.75 x 10.2 x 1.5 in, 2.4 lb | 23.4 x 15.1 x 1.5 in, 6.4 lb plus kickstand |
| Typical power draw | 25 to 40 W | 75 to 100 W |
| Input | 12 to 48 V DC, USB-C PD or DC 5521; runs directly on 12 V | 100 to 240 V AC to the router; router feeds 48 to 57 V PoE to the dish |
| Overnight from a 100 Ah 12 V bank | 25 to 30 Ah, about a quarter of the bank | 80 to 100 Ah through an inverter, most of the bank |
| Router | Built into the dish, Wi-Fi 5 | Separate Gen3 router, Wi-Fi 6, mesh capable |
| Throughput, typical | 50 to 150 Mbps down | 100 to 250 Mbps down |
| Cable | Standard USB-C or DC lead, easy to route; 49 ft max with the Mini cable | Proprietary waterproof RJ45-style cable, 50 ft supplied, 15 and 150 ft available; cannot be spliced |
| Through the wall | DC 5521 pass-through socket | IP68 Cat6 female-to-female socket |
| In-motion use | Allowed on Roam/Mobile Priority with a fixed mount | Allowed on Mobile Priority with a fixed mount; kickstand is not a vehicle mount |
| Mounts | fixed, magnetic, suction, rail | pipe, J-arm, ridge, flat roof adapter |
| Hardware cost to install properly | about $150 to $250 | about $200 to $350 plus inverter or 100 W injector |
Where the Mini wins
Anything on 12 V. A van, a small RV, a sailboat, a work truck or a job trailer runs the Mini from the house battery with a 100 W charger or a hardwired injector and no inverter, at a third of the Gen3's power. It fits a rail or a roof rack, it packs in a hard case, and a 95 Wh battery bank runs it three hours away from the vehicle. For most mobile users the Mini's 100 Mbps is more than the cell hotspot it replaces.
Where the Gen3 wins
Throughput and Wi-Fi. A family RV with four devices streaming, a live-aboard working full time, or a cabin used as a home office gets the Gen3's higher speed and its Wi-Fi 6 mesh router. It needs a real DC system: a 200 Ah or larger bank, an inverter or a 100 W DC-to-56 V injector, and a flat mounting area. The proprietary cable means the only clean way through a wall is the Cat6 bulkhead socket, which also lets you swap to an ordinary patch cable inside.
Recommendation by vehicle
| Vehicle | Pick | Why |
|---|---|---|
| Van, truck camper, Class B | Mini | 12 V native, small roof, small bank |
| Travel trailer, Class C | Mini, unless four or more heavy users | Power and roof space |
| Class A, fifth wheel, full-time | Gen3 | Big bank, big roof, Wi-Fi 6 for the coach |
| Sailboat under 45 ft | Mini | Rail mount, 30 Ah a night |
| Trawler, sportfisher, live-aboard | Gen3 | Hardtop, house bank, speed for work |
| Work truck, fleet | Mini | four-part kit, in-motion, no inverter |
| Cabin, remote office | Gen3 | Speed and mesh, grid or generator power |
Install hardware, both dishes
Mini: fixed mount, charger or injector, DC socket, fuse and 12 AWG, chassis bond. Gen3: mount adapter, Cat6 socket, patch cable, surge protector at the entry, bonding jumper. Both lists are in stock on the Starlink page, with install guides for RV and van, boats and Gen3 in an RV or cabin.
