See the full story

TITANSHIELD Air is the thinnest in the series: 6 mm, 113 g. In a pocket you barely notice it.

The cell uses a semi-solid-state formulation: the electrolyte is held in a polymer matrix instead of flowing freely the way it does in a conventional liquid lithium battery.

A semi-solid-state power bank -
why does puncturing it do nothing?

Because the layer separating the electrodes is semi-solid-state.

Cathode layer Solid-state electrolyte Holds its structure when punctured Liquid electrolyte Leaks once breached Electrode contact, thermal runaway Anode layer

After a steel pin pierces the semi-solid-state electrolyte, it keeps its original structure - it doesn't flow, and it doesn't bridge the electrodes. So in the puncture test, the response only rises to 44.0°C, then stops there.

Most power banks use a liquid electrolyte. Once the separator is punctured or torn, the liquid leaks out and the electrodes make direct contact - the heat from the short circuit pushes the reaction further, which is thermal runaway, the fire and explosion you see in the news.

Not just puncture.
Five tests, zero fires.

Cell safety testing by SGS Taiwan -- pushing the battery to its limits to see if it fails. Every figure below is raw data from the report.

Puncture

A 4.0 mm steel nail with a 32-degree cone drives all the way through the cell at 40 mm per second.

44.0°C

No fire, no explosion

Thermal abuse

Fully charged, then heated in a chamber at 5°C per minute up to 130°C and held there for 60 minutes.

130°C / 60 min

No fire, no explosion

Overcharge

Charged at 5A without stopping, all the way to 4.7V and past the one-hour mark.

32.0°C

No fire, no explosion

Over-discharge

Discharged at 5A for 1.5 hours straight, until the cell is drained.

58.4°C

No fire, no explosion

External short

The terminals are shorted directly through a 15.14 mOhm external resistance.The cell's own tab fuses and opens the circuit.

23.4°C

No fire, no explosion

BSMI R3I037 NCC Pending

Conducted by the SGS Taiwan reliability laboratory. Reports HE40037/2026 (May 8, 2026, covering overcharge, over-discharge, external short and thermal abuse) and HE50024/2026 (June 10, 2026, puncture). The sample was the cell used in this product, model 486578. Each figure is the peak surface temperature recorded in the report and represents the tested sample only.

FAQ

How does the warranty work?
Every unit comes with a 1-year warranty. Register it on our site and we add a second year, for 1+1 years in total. The warranty covers defects and failures under normal use. It does not cover consumables or damage from external force.
Can I take it on a plane?
Yes, in your carry-on. The Air's 5,000 mAh cell is rated at about 19.25 Wh, well under the 100 Wh airline limit. One reminder: power banks always travel in the cabin and can never go into checked baggage.
My phone has no MagSafe. Can I still use it?
Any phone that supports wireless charging works. If your phone has no magnets, add a stick-on magnetic ring, or just plug in the Type-C cable.
Does the Air have the safety alarm?
No. The safety alarm and the TFT display are Pro features. The Air is built to be as thin and light as possible and keeps its safety out of sight: a semi-solid-state cell, SGS testing and six layers of protection. If you want the audible warning, look at the Pro.
How is the Air different from TITANSHIELD and the Pro?
The Air is the thin one: a 5,000 mAh magnetic power bank at 6 mm and 113 g. TITANSHIELD is the everyday all-rounder and adds Apple Watch charging. The Pro is the flagship, with the safety alarm, a TFT display and 25W fast charging. The comparison table above has the details.
How do returns work?
Every order has a 7-day return window that starts on delivery. If anything is wrong with the product, request a return within those seven days. The window is for inspection, not trial use: returned items must be in new condition with complete packaging. See our return policy for the details.
How is a solid-state power bank different from a regular one?
The difference is the electrolyte that separates the two electrodes. A regular power bank uses a liquid electrolyte: when the separator is damaged the liquid escapes, the electrodes touch, and thermal runaway can start a fire. A solid electrolyte keeps its structure even when it is pierced. The cell in TITANSHIELD Air went through the SGS steel-nail penetration test and peaked at 44.0°C, with no fire and no explosion.
Why do power banks catch fire, and how do I avoid it?
Almost every fire starts as thermal runaway in a liquid electrolyte: the cell is crushed, pierced or overcharged, the separator fails, the electrodes short, and the temperature climbs in a chain reaction. It is generally recommended to choose a product with safety certification and overcharge protection, never charge it under a blanket or pillow, and stop using it as soon as the case swells. The Air reduces that risk at the cell: a semi-solid-state electrolyte does not flow, backed by six protections and NTC thermal control.
