“I checked the battery charger, not just the camera body; the charger was the part connecting directly to Guam’s 110 V supply.”

Will my camera battery charger work on Guam’s power supply?
For Guam, verify the exact camera equipment instead of relying on a country-level assumption. Start with the battery charger or USB-C wall adapter, not the camera body. Guam supplies 110 V at 60 Hz through A · B outlets. A charger whose INPUT range includes the local supply can handle the electrical side of the trip.
A charger designed only for 220–240 V may be unsuitable on 110 V; camera brands often have multiple charger generations, so verify the exact accessory rather than assuming every charger for the same battery is identical. Across different accommodations in Guam, a tested camera power setup is easier to repeat.
Guam power: A · B · 110 V · 60 Hz
See the Guam power plug guide →Which camera charger plugs need an adapter in Guam?
The A · B outlet family answers plug fit for a camera, not whether it accepts 110 V. For plug fit, compare the AC side of every charger in the camera bag with A · B. A detachable wall lead can sometimes be swapped for a local-compatible cable. In Guam, that may be tidier than adding an adapter behind a bulky two-battery charger.

A hotel-room workaround in Guam should not replace checking dedicated charging versus USB-C before departure. USB-C can simplify a Guam camera kit when the body supports the required charging mode. It is still worth carrying the dedicated charger if you want one battery charging while another stays in the camera. The right choice depends on the camera’s USB behavior, charging speed and how long you expect to shoot away from the hotel.
How to read a camera charger label for Guam
Testing the complete camera setup before Guam keeps the travel-power kit simpler. Read the INPUT line for both voltage and frequency. A marking such as 100–240V ~ 50/60Hz includes 110 V / 60 Hz. Photographing the charger label before leaving for also gives you a quick reference if the accessory stays buried in the bag.

Once avoiding an unnecessary converter is confirmed for Guam, extra conversion hardware is easier to avoid. A converter is usually the wrong tool for a modern universal-input camera charger. When the charger already accepts 110 V, a converter does nothing useful. If an old proprietary charger does not, a manufacturer-approved wide-input replacement is often a simpler travel solution than building the photo kit around conversion hardware.
