The power bank that
shows its work
26,250mAh. Three ports. Live wattage per port on the display. It charges two MacBook Pros simultaneously and recharges itself to 50% in thirteen minutes. Heavy because it has to be.
USPS ShippingEvery watt accounted for,
every port labeled live
Most power banks are a black box. The Nexus 300W puts the numbers on its face: wattage per port, state of charge, input rate. You stop guessing whether your cable is limiting you. You know.
Two USB-C and one USB-A port running simultaneously. Two MacBook Pros at full speed isn't a marketing claim — it's the math on the display.
Plug a 5A USB-C cable into port 1 and the Nexus delivers a full 140W to your MacBook Pro. MacBook Pro M4 Pro to 50% in 27 minutes.
Industry-first 250W combined USB-C input. Two power bricks filling both ports takes the Nexus from flat to 50% in 13 minutes. Fits a coffee queue.
Real-time per-port data via Bluetooth. Manually adjust output power, set charge limits, monitor temps. You're not just watching numbers — you're setting them.
Deliberately under 100Wh. No special approval needed, no gate check, no argument at security. It's in your carry-on. You board. That's it.
Percentage remaining, wattage in, wattage out per port. You'll start noticing when a cable is underperforming. It turns out that's surprisingly often.
Phantom Gray. Solid as it looks.

Why the numbers matter
Most power banks top out at 65W. A few reach 100W. The Nexus runs at 300W combined output with 250W input. The gap is real.

What happens after 30 days
Honestly thought this would live in a suitcase. it's too heavy for a slim shoulder bag — that part is true — but the dock changed everything. Leave it on the base in the kitchen, it charges through passthrough, and i just grab it when i need it. the display showing charging rate per device was the feature i didn't know i needed. turns out one of my cables was capping at 18W. good to know.
Run client sessions with my MacBook and a backup PC simultaneously. The 3-port setup with 300W means both run at full rated charge speed. The display confirmed it. Nothing throttled.
Six hours of studio sessions and it still had 40% left. The percentage is right there on the front — not guessing anymore.
My daughter set this up for me after i kept running out of power on long flights. took me a few days to get the app working properly — the Bluetooth pairing wasn't obvious — but once it connected i could see exactly what it was doing, which is the kind of transparency i appreciate. charged my iPad and phone at the same time across the Atlantic. neither one dropped below 90%.
My brother does location scouting — always hiking with gear and no outlets. He called me the same evening he got it to describe the wattage display in detail. That says enough.
Used to buy the cheap 20,000mAh ones every year and they'd die in 8 months. This felt like a different category entirely — the build quality is noticeably solid, the dual USB-C input recharged it in under an hour, and it's been consistent across three months of daily use.
