    How Long Does a Starlink Mini Run on a Battery?

    How long does a Starlink Mini run on a battery? It's one of the questions we hear most. Getting online with the Mini is the easy part. Keeping it powered when there's no outlet is where most setups fall apart.

    This guide walks through the honest math, why most power banks fall short, and how to pick between our two batteries: the Veritas 5-Hour Battery and the Veritas 45-Hour Battery.

    Veritas 5-Hour Battery: best for day trips and grab-and-go

    The 5-Hour Battery becomes part of the Mini. Pull off the Mini's factory kickstand, click the battery into its back, flip out the battery's own kickstand, plug in, and you're online. Dish and power become one piece of gear.

    It's 99Wh, so it's airline carry-on friendly. Plan on up to about 5 hours with light use, and less on a heavy day. It's IP67 with an all-metal body, so rain, dust, mud and a brief dunk are fine. It refills in about 1.5 hours on a 100W USB-C charger, or about 2 to 3 hours over DC. In the box: the battery, a DC cable for the Mini and a 100W USB-C cable.

    Want it on your vehicle? Add the Veritas Battery Mini Mount Adapter, or order the battery with it. The adapter swaps in for one frame piece of our Starlink Mini Mount and holds the battery in place, so dish and battery sit in the mount together. The Mini Mount is marine-grade HDPE, CNC machined in California, and covered by our Lifetime Guarantee.

    Veritas 45-Hour Battery: best for multi-day, off-grid and backup

    If a few hours won't cut it, the 45-Hour Battery holds 896Wh. That's up to about 45 hours with light use, or about 22 with heavy use. Even on a heavy day, that's most of a day online without an outlet, an engine or the sun.

    It lives in a hard travel case built around it. Fitted foam holds the battery, and a tray is cut for the Starlink Mini Mount, so the whole setup travels as one box. The case has its own outside ports and a power button, so you can run everything with the lid shut.

    The battery is splashproof. Rain and spray are fine, but don't dunk it or leave it in standing water. The case is waterproof when it's closed. Battery and case weigh about 26 pounds, and a 100W USB-C charger comes with it.

    Questions We Get A Lot

    Divide the battery's watt-hours by about 20 to 40 watts, the Mini's typical draw. A 99Wh battery gives roughly 2.5 to 5 hours, and an 896Wh battery roughly 22 to 45 hours. Real run time lands a little under the math and depends on use, weather and obstructions.

    It depends on how you use it. For day trips, flights and grab-and-go, the Veritas 5-Hour Battery clicks into the back of the Mini and is carry-on friendly. For multi-day trips, off-grid work or backup, the Veritas 45-Hour Battery runs from its travel case, even with the lid shut.

    Up to about 5 hours with light use. That's 99Wh ÷ 20W, and some energy is always lost along the way, so real run time lands a bit under the math. Heavy use, heat and a blocked sky bring it lower. The display and app show your real time left.

    Usually not a phone-size one. Over USB-C, the Mini needs a laptop-class source of 60 watts or more. A small bank may not turn the Mini on at all.

    Yes. Both Veritas batteries do pass-through charging, so the Mini stays online while the battery refills from the wall, your vehicle or solar.

    The Veritas 5-Hour Battery is 99Wh, which keeps it under the common 100Wh carry-on limit for lithium batteries. Check your airline's rules before you fly.
