Puncture it.
Then measure the temperature.
The puncture test is the most direct of the cell safety tests -- a steel nail is driven through the cell body to see if it goes into runaway. The cell used in TITANSHIELD Air was sent for this test.
Voltage 4.458 V before the test, 0 V after.
Peak temperature 44.0 °C, and no runaway: no fire, no explosion.
Test conditions: 4.0 mm steel nail, 32-degree cone, 40 mm/s penetration speed, 100% penetration through the center of the largest face, ambient 77 ± 4°F (25 ± 2°C). Conducted by the SGS Taiwan reliability laboratory; report HE50024/2026 issued June 10, 2026. The sample was the cell used in this product (model 486578). The test was performed by trained staff in a laboratory. Do not attempt it yourself.
A semi-solid-state power bank -
why does puncturing it do nothing?
Because the layer separating the electrodes is semi-solid-state.
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
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.
Thin, but
nothing cut short.
Seven layers stacked into a 6 mm body -- from the aluminum shell to the reinforced glass panel, each with its own place. Scroll down to see them one by one.
Snaps on.
Stays on.
N52 magnet ring. Holds tight, even upside down.
6 mm.
Still lies flat in a shirt pocket.
103.3 x 69.0 x 6 mm. The three bars below are drawn to actual scale in millimeters.
113 g.
Light enough to forget it's there.
About the weight of a lemon, much lighter than a phone. Carry one extra and your shoulder won't notice.
Aluminum body.
It doubles as a heat sink.
The shell is more than a shell. Heat from the cell during charging spreads across the whole aluminum body; a plastic shell can't do that, so heat just gets trapped inside.
Aluminum
150-170W/m·K
Heat spreads from the center across the whole body, so it feels evenly warm.
ABS / PC plastic
0.2-0.3W/m·K
Heat cannot escape. It pools around the cell and one small patch runs hot.
The figures are the usual thermal conductivity ranges for aluminum and ABS / PC plastic, a difference of roughly 600 times or more. Both illustrations and the curves above show the principle only; they are not measured thermal images.
So light,
you forget it.
Drop it in a pocket and go. All day, you never feel the extra weight.
Set it down
and charging starts.
Align it with the magnetic charging zone and it starts automatically. Cabled works too -- 15W magnetic wireless or 18W wired Type-C, both from the same body.
Magnetic wireless
Type-C wired
Magnetic wireless charging, AirPods included
15W wireless. Twice the old 7.5W standard.
In the same stretch of time, twice as much energy goes in. While many wireless pads are still at 7.5W, this one has already finished.
The curves illustrate the principle: double the power, and roughly double the energy goes in over the same time. Real charging times vary with the device, the remaining charge and the ambient temperature.
Phone on top.
Earbuds on the side.
The phone charges magnetically on top while a Type-C cable charges your AirPods or watch case. One power bank covers two devices, so there is no second one to carry.
With both outputs running, each side gets half the power. For low-draw devices like earbuds, double-press the power button to enter low-current mode so they are not mistaken for fully charged and cut off.
5,000 mAh.
Enough for about one full phone charge.
Every phone's battery is a different size, so the charge it gets differs too. Below are the results for iPhone, Samsung and Google flagships.
These are rough estimates. How much you can actually recharge varies with the device, its remaining charge and how it is used.
Holds on,
won't let go.
N52 magnets, meeting the same 1.5 kg standard as Apple MagSafe. It locks on, it doesn't just sit there -- it won't slip during a walk, in your pocket, or a one-handed swipe.
We took the body down to 6 mm and kept the magnetic hold at 1.5 kg. Thin does not have to cost you grip.
0.0kg
Magnetic hold, on par with Apple MagSafe.
At 6 mm thin, that number never gave way.
Six-layer protection,
one chip watching the whole time.
Every second of charging and discharging, the protection chip watches voltage, current and temperature - and steps in the instant something goes wrong, before you'd ever notice.
- Overvoltage protection
- The moment voltage crosses the threshold, output is cut.
- Overheat protection
- At 45°C it throttles and keeps charging, then returns to full power once it cools.
- Overload protection
- If output climbs abnormally, it locks at the ceiling and limits current.
- Overcharge protection
- Full means full. No force-feeding, no trickle abuse of the cell.
- Short-circuit protection
- A short-circuit surge opens the circuit instantly and saves the cell.
- FOD foreign-object detection
- Put a key or a coin on the charging area and output stops at once.
Precise NTC temperature control
An NTC temperature sensor inside the body monitors the cell in real time. At 45°C, it doesn't cut power outright - it throttles and keeps charging, so it stays cool to the touch without stopping.
The 45°C throttle threshold comes from the product manual; the six protections' trigger points and curves are illustrative - actual behavior depends on the product firmware.
Corner radius, matched without a seam.
CNC-machined from a single block of aluminum, with a corner radius that sits flush - stacked with a MacBook, it looks like a native accessory. Apple fans will notice.
Graphite Black. Polar Silver.
Scroll to turn it all the way around. The MagSafe magnet ring, the seamless aluminum side, the 2.5D curved edge, the Type-C port. Every face, up close.
First in Asia. Now in the US.
