Why it's on my list
The power half of the lightest kit in my backup-internet guide: it runs a Starlink Mini off a USB-C to DC cable, sits just under the FAA's 100 Wh carry-on line, and charges a laptop at 140 W.

What it is
A power bank with a real AC outlet: 99.9 Wh, under the FAA carry-on limit. 21700 cells, 160 W total output, 140 W USB-C PD 3.1 for a laptop, 100 W AC outlet (150 W peak). The one in the backup-internet guide for running a Starlink Mini or a router off the grid.
What it is
A power bank with a real AC outlet, just under the carry-on line, that runs a Starlink Mini off a USB-C cable
This is the power half of Option 1 in my backup internet guide, the smallest real-deal kit I've tested: a Starlink Mini running off a station that fits in a jacket pocket and flies carry-on. Under two pounds, a 99.9 Wh pack rated just under the FAA's 100 Wh limit, and five ways to push power out, including a 140 W USB-C port that feeds the dish directly. Total spend on the power side, cable included, is roughly $150.
Five ways out
A wall plug in your pocket, plus four USB ports
Why it matters
The AC outlet runs anything with a standard plug. The first USB-C port does 140 W of Power Delivery, up to 28 V at 5 A, which covers the 20 V profile the Starlink Mini wants and charges a laptop at full speed. The USB-A ports run headlamps, radios and battery chargers. The screen shows real-time watts in and out, and the 150-lumen flashlight in the end is a bonus, not a gimmick.
The numbers
- AC outlet: 100 W continuous, 150 W peak
- USB-C 1: 140 W Power Delivery (up to 28 V / 5 A)
- USB-C 2: a lower-wattage port for a phone or GPS
- Two USB-A ports: 18 W each
- 21700 lithium-ion cells with a battery management system; screen for input and output watts
- 150-lumen flashlight
Running the Starlink Mini
The AC route and the DC route
Why it matters
Plug the Starlink brick into the AC outlet and it works, but the station inverts DC to AC and the brick converts it right back: 15 to 25 percent of the battery goes up as heat. The Mini accepts 12 to 48 volts through its barrel jack, so a $10 USB-C to DC cable pulls 20 V straight from the 140 W port into the dish. Ten dollars for 20-plus percent more internet is the easiest math in the guide. Buy the 100 W-rated cable, not a 65 W one: the dish spikes to 40 to 60 W while it boots, and an undersized cable drops out right as it locks on.
The two ways
- AC route: Starlink brick into the outlet; zero extra parts, double conversion
- DC route: 100 W USB-C PD cable with the 5.5 x 2.1 mm barrel plug, 20 V direct to the dish
- Continuous dish time: about 3 to 4 hours
- Checking messages and weather a few times a day stretches one charge across days
Recharging it
An hour on a wall charger, and the same port takes solar
Why it matters
From empty in about an hour on a 100 W USB-C charger, and any panel with a USB-C PD output refills it in the field. It is the battery I'd keep in the bug-out bag and the travel kit; for a day and a night of dish time the Star-Batt is the next step, and for no countdown at all, the DELTA 3 Classic with a panel.
The numbers
- About 1 hour from empty on a 100 W USB-C charger
- Recharges from any USB-C PD solar panel
- Under 2 pounds; flight approved
