NOT A REPURPOSED POWER BANK.
Built for One Thing.
Built to Do It Right.
Every power bank says it works with Starlink Mini.
SINVYX was engineered specifically for it — and the difference shows.
THE SINVYX STORY
We Asked a Simple Question.
Nobody Had a Good Answer.
Starlink Mini changed what it means to stay connected off-grid. But when we looked at what people were using to power it — generic USB-C power banks, jerry-rigged adapters, workarounds — we saw the same problem everywhere.
The hardware was brilliant. The power solution wasn’t.
So we built one from scratch. Not by taking an existing power bank and calling it “compatible.” By starting with Starlink Mini’s actual voltage requirements, its real power draw, and the conditions people use it in — rain, sand, salt air, mountain cold.
SINVYX is the result.
Purpose-built, properly certified, ready for wherever you take it.
Partners Who Trust SINVYX
ADVANTAGE 01
More Runtime.
Not More Marketing.
Most power banks output USB-C at 5V or 20V. Starlink Mini needs 15–21V DC to run.
When you connect a USB-C power bank, the battery converts its voltage up — then the Mini converts it again internally. Twice. Every conversion loses energy as heat. You’re paying for watts you never get.
SINVYX outputs 15–21V DC directly. No intermediate conversion. No heat loss. The watts in the battery are the watts powering your dish.
Purpose-built, not repurposed.
Output: 15–21V DC — purpose-matched to Starlink Mini input
Configuration: 5S2P with self-developed BMS
Result: ~15–20% more usable runtime vs USB-C path
ADVANTAGE 02
The People Who Need This Don’t Stay Indoors.
Travelers. Van lifers. Sailors. Overlanders. The people buying a Starlink Mini battery aren’t sitting in a living room.
IP65 isn’t a checkbox for us. It’s a baseline requirement. Every single SINVYX model ships IP65-rated — not just the expensive one. Because weather doesn’t care which model you bought.
Work outside. No excuses.
- ✓ Heavy rain — no problem
- ✓ Sand and trail dust — fully sealed
- ✓ Salt air and sea spray — handled
- ✓ Operating temp: -20°C to 60°C (-4°F to 140°F)
- ✗ Submersion — not rated for underwater use
ADVANTAGE 03
You Shouldn’t Have to
Wonder What’s Inside.
The Starlink Mini battery market is new. And like any new market, it attracts products that look the part but don’t hold up when you ask the hard questions.
What cells are actually inside? Has this been independently tested? What happens if something goes wrong at 30,000 feet?
SINVYX answers all of it. Samsung / LG 21700 NMC cells, EVE 21700 NMC for the 158Wh — tier-1 manufacturers used in commercial energy storage worldwide. Every unit tested before it ships.
Not certified on paper. Certified in practice.
Cells: Samsung / LG 21700 (99Wh, 180Wh, 200Wh) · EVE 21700 (158Wh)
BMS: Self-developed — overcharge / over-discharge / short circuit / thermal cutoff
Certifications: UN38.3 · UL2743 · FCC · ISO 9001 · ISO 14001
