01 / MATERIALS
Why semi-solid matters.
Semi-solid battery designs can immobilize electrolyte in a gel-like structure, helping limit the movement and volatility of flammable liquid components. This approach can reduce leakage and ignition risk, making cell chemistry an important part of the safety story.
02 / CELL-LEVEL SAFETY
Why nail penetration matters.
Nail-penetration testing deliberately creates an internal short circuit to assess how a cell responds to severe physical damage. A result showing no fire or explosion is meaningful evidence for the tested cell under the stated conditions; it is not a guarantee for every use or damage scenario.
Semi-solid cells remain lithium-ion batteries. Cell design, protective electronics and the finished product all contribute to safety. Cell-specific test evidence and conditions should be reviewed for your project.

Individual output ratings are not simultaneous. Combined output: 15W max. Charging performance depends on device compatibility and charging conditions.
01 / INTEGRATED CHARGING
Built-in USB-C cable.
Up to 45W output.
The built-in USB-C cable stays with the power bank, so users can connect without packing a separate cable. Both the USB-C port and integrated cable support up to 45W on a single output.
For your lineup: a practical feature that is easy to demonstrate, explain and use every day.
02 / EVERYDAY CONVENIENCE
Everyday convenience.
Designed in the details.
A fold-out stand supports hands-free viewing, while the digital display keeps battery and charging information visible. Useful details turn a charging accessory into a companion for the desk and beyond.
For your customers: charging, viewing and power information in one considered design.
03 / MORE WAYS TO CHARGE
Distinctive on shelf.
Useful in hand.
Wireless charging for compatible phones and watches adds more ways to use the same product. Pair these capabilities with the built-in cable and three refined finishes to tell a clear product story.
Clear specifications: up to 15W phone wireless charging and 2.5W watch charging. Compatibility is reviewed for your project.
Interactive product visualization. Finish appearance varies with lighting; final details are confirmed with your approved sample.

Private-label power bank FAQ.
What makes the T214 cell technology different?
T214 uses ATL semi-solid lithium-ion cells, with safety as a core part of the product specification. Semi-solid technology is intended to improve electrolyte stability and reduce ignition risk. It should be evaluated together with the finished product’s protective design.
Does passing a nail-penetration test mean a battery is fireproof?
No. A no-fire, no-explosion result describes the tested cell under specific conditions. Confirm the exact cell model and supporting test documentation for your project; a cell-level result is not a guarantee for the complete power bank under every condition.
Can we add our logo and customize the product?
Logo placement, finish and packaging are reviewed against your brief. Final options and artwork are confirmed for your project before sample approval.
Can we review a sample before production?
Include your sample requirements in the project brief. Sample availability, cost and timing are confirmed before you proceed.
What are the MOQ and production lead time?
These depend on the selected finish, customization, packaging and order quantity. Share your target volume and launch schedule so we can review the appropriate production plan.
Can you support our target market requirements?
Share your destination market and required documentation. We will review the applicable product and labeling requirements; model-specific certification status is confirmed during project review.
Do all charging outputs run at maximum power together?
No. The individual ratings are separate maximums. Combined output is 15W max. Actual charging also depends on the connected devices and charging conditions.
