Compatible Replacement Battery

The Cameron Sino W19 is a new lithium-ion replacement cell built for Skyroam W19, W19H and W20 hotspot devices. It matches the original 2700mAh capacity and 9.99Wh energy rating at 3.7 volts. Travellers and remote workers who rely on these hotspots can restore factory runtime without changing chargers or cables.

Practical Capacity and Voltage Limits

The 2700mAh cell delivers 9.99Wh at a nominal 3.7 volts, so total energy is fixed by chemistry and cannot be increased by firmware. Users should expect runtime to follow the original specification and plan charging cycles accordingly. A fresh unit reaches its best performance after two or three full charge and discharge cycles.

Build Quality and Daily Handling

The pack measures 56.00 by 49.30 by 11.30 millimetres and weighs 68.5 grams, fitting the original battery compartment exactly. An integrated protection circuit guards against overcharge, over-discharge, over-voltage and short circuits. The package includes shock-absorbing foam for safe transport, and the decoded chip communicates with the hotspot just like the stock battery.

Questions about this item

Which Skyroam hotspot models does this 2700mAh battery fit?

The W19, W19H and W20 models all use the same W91H part number, so this 2700mAh / 9.99Wh cell replaces the original in any of them.

What runtime can I expect from the 9.99Wh rating in my hotspot?

At 3.7 volts the cell stores 9.99 watt-hours; a typical hotspot drawing 1–2 watts will run roughly five to ten hours on a full charge.

Does the battery use a standard connector or a proprietary interface?

It uses the original Skyroam connector for the W19 series; the decoded chip communicates with the hotspot exactly like the factory battery.
