Verified Buyers Say
From Recent Customers
★★★★★
300W in a power bank — this actually delivers
Picked this up after seeing the wattage spec and being skeptical. Running two USB-C devices simultaneously and the display shows exactly what each port is pulling. MacBook charged from 15% to 100% before my meeting ended. The weight is real but so is the output.
★★★★★
Bought it for travel, kept it for the kitchen counter
Originally got this for a trip but it ended up living on the dock at home. The pass-through charging means it's always full — I just grab it when I need it and put it back. The display tells me what's charging at what rate, which I didn't know I'd care about until I did. Three-port setup handles the whole family simultaneously.
★★★★★
Charges fast in, charges fast out
Full recharge in under an hour using two power bricks simultaneously. Three ports running at the same time without throttling. The Bluetooth app actually works — I can check which port is drawing what without picking up the unit. Premium feel from the chassis to the braided cable it ships with.
★★★★★
The display alone is worth it
I have some older charging accessories that don't show any status — just a light. This shows watts per port in real time. Figured out my old USB-A cable was capping my phone at 18W instead of the full rate. Replaced the cable, problem solved. Wouldn't have known without this readout. Heavy but fits in my bag no problem.
★★★★★
Cleared TSA with zero issues
Took it through four airports on a two-week trip. Zero questions, zero problems — just went through like any other carry-on item. On the flights, charged my MacBook from dead to working before the food service. The pouch it comes with is a nice touch for tossing it in a bag without scratching anything.
★★★★★
Solid build, no heat, dual charge capability is real
Used it hard for several weeks — charging my laptop twice through and never had it get warm. The dual-port input charges it back up in under an hour when I use two bricks. I've had cheaper banks that got uncomfortably hot during charging sessions. This one stays cool and keeps going. Durable, heavy, worth the price.
Common Questions
Before You Order
Why does the power bank sometimes charge fewer cycles than expected?
All power banks lose some energy to heat and conversion during the charging process — typically 10-20% of rated capacity. The 26,250mAh figure is cell capacity; real-world delivery to your devices will be slightly lower depending on the output voltage your device requests and how efficiently the bank converts it.
Can it charge and recharge at the same time (pass-through)?
Yes, when paired with the optional charging base it supports full pass-through — devices connected to the bank charge while the bank itself recharges from the dock. Without the base, standard pass-through via USB-C is supported but may limit output to devices during simultaneous input charging.
Is it actually TSA-approved for all airlines?
At 99.75Wh it falls under the standard 100Wh threshold that TSA and most international aviation authorities allow in carry-on bags without airline-specific approval. The vast majority of airlines worldwide accept it without requiring permission. Always verify with your specific airline for international routes, as rules vary.
Does the 140W single-port output work with all laptops?
The 140W output requires a 5A USB-C cable (included in the box) and a device that supports high-wattage USB-C PD charging. MacBook Pro (M4 and M4 Pro), most recent MacBook Air models, and many Windows ultrabooks support this. Older devices or those with lower-rated ports will receive power at their supported maximum rate.
What does the app actually let me do that the display doesn't?
The physical display shows current wattage per port and overall battery level. The app adds remote monitoring without picking up the unit, thermal alerts, firmware update notifications, device profile presets, and the ability to adjust maximum output per port — useful when you want to prioritize one device over another during a limited charge session.
Is the charging base sold separately or included?
Two configurations are available: the Power Bank alone, and the Power Bank + Charging Base bundle. The base enables pass-through charging, wireless status monitoring via the app, and more convenient at-home docking. Select your preferred set using the variant selector on this page.
24-Month Warranty
Full manufacturer warranty covering defects in materials and workmanship for two years from purchase.
