16 V 4.5 A adapter for Toughbook

This AC adapter supplies 16 volts at 4.5 amps through a 5.5 by 2.5 mm barrel connector. It is built for Panasonic Toughbook models including the CF-19, CF-29, CF-30, CF-31, CF-52 and CF-53. The unit accepts 100 to 240 volt input at 50 or 60 hertz for worldwide use. A detachable power cord is included in the package.

Suits field-service teams; not for other laptops

Technicians maintaining fleets of the listed Toughbook models will find a direct replacement here. The adapter matches the original voltage, current and connector dimensions. Buyers who need a different output voltage, a higher wattage rating or a connector size other than 5.5 by 2.5 mm should look at something else.

72 W output at 16 V decides fit

The single specification that determines compatibility is the 16 volt, 4.5 amp, 72 watt output delivered over the 5.5 by 2.5 mm tip. If the target laptop requires exactly that combination the adapter will work; if it requires a different voltage, amperage or tip geometry it will not.

Questions about this item

How do I connect the 5.5*2.5 mm barrel plug to my Toughbook CF-31 without damaging the port?

Align the centre pin with the socket, push straight in until it seats firmly, then route the cord so the brick hangs free — forcing the cable sideways bends the pin and cracks the jack.

Which parts of this 72 W adapter wear out first and when should I replace them?

The DC cable near the barrel plug frays from repeated bending; the input cord can crack at the strain relief. Replace the whole unit if output drops below 16 V or the brick becomes hot to the touch.

What thermal limit appears first when the adapter runs at 4.5 A continuously?

The sealed enclosure relies on passive convection; sustained 72 W load raises case temperature until the internal over-temperature protection cycles the output off until it cools.
