Questions, answered
SolidSafe™ FAQ.
The useful details, without the battery jargon.
What does semi-solid-state mean?
SolidSafe™ batteries use significantly less liquid electrolyte than conventional lithium-ion batteries. That construction helps reduce fire risk while keeping the power bank practical for everyday use.
Which one charges my laptop?
SolidSafe™ 20K delivers 100W over USB-C and charges a MacBook Pro 14-inch at full speed. SolidSafe™ 15K delivers 65W over USB-C for MacBook Air class laptops. SolidSafe™ 10K is made for phones and small devices at 30W.
How many devices can I charge at once?
SolidSafe™ 15K and 20K charge three devices at once from two USB-C ports and one USB-A port. SolidSafe™ 10K charges two at once.
Do older USB-A cables work?
Yes. Every model has a USB-A port alongside USB-C, so earbuds, a Kindle or an older cable work too.
Is a cable included?
SolidSafe™ 10K has a built-in USB-C lanyard cable, and SolidSafe™ 15K has a USB-C lanyard cable. SolidSafe™ 20K comes with a separate 1m braided USB-C cable, rated for 140W.
Can I bring one on a flight?
Every model is under 100Wh: 37Wh for the 10K, 55.5Wh for the 15K and 74Wh for the 20K. Power banks must travel in carry-on baggage, not checked baggage. Airline and local rules can vary, so confirm before you fly.
Do these charge wirelessly?
No. These are wired USB-C and USB-A power banks. For magnetic wireless charging, see the SolidSafe™ magnetic collection.
