Using it abroad

E-Reader (Kindle / Kobo)

Use a plug adapter only after confirming that your actual input rating covers the local voltage and frequency. Match your real plug and preserve any required grounding. An adapter does not change voltage.

Label-compatible scenarios

More destinations+34

Check your label first.

Compatibility is unconfirmed. Read the exact INPUT voltage range and frequency on your device or power supply, and compare them with the destination. The whole local range must be covered; 110–220V does not include 100V or 230–240V. Confirm the actual plug, grounding and manufacturer restrictions. Do not plug in while these details are unknown.

How to read the INPUT label

Read the INPUT rating on the exact device or AC supply: V = voltage, Hz = frequency, A/W = current/power. USB/DC OUTPUT ratings are not the AC input range or measured wall consumption. Match the full local voltage and frequency, plug, grounding and manufacturer instructions. A 100–240V label covers only that range; 120–240V does not include Japan’s 100V. If the label is missing or unclear, do not connect until confirmed.

Model facts and sources

Document scope: Kobo Libra Colour model N428; no exact external AC adapter is identified.

The model support page identifies N428, not a wall-charger AC rating. Check the separate charging supply; generic USB guidance is not evidence for every external adapter.

Model facts and sources

Document scope: Kobo Libra Colour N428 with actual Motorola SC-41 black SKU SJMC101-C-JP, 5 V/2 A USB-A output and compatible USB-A to USB-C cable.

Compatibility is a bounded inference from Kobo’s permitted 5 V/2 A USB charging path and Motorola’s matching output/cable, not a named Kobo endorsement. This adapter is not bundled with N428. Other SC-41 variants, grounding and AC watts are not verified.

Scope

Kobo: Charge your Kobo eReader: Charging tip / Notes: USB computer or compatible adapter, 10 W 5 V suggestion; high-wattage fast-charge and differing electrical-system cautions. Device-side DC guidance does not establish the wall supply AC input or no-earth behavior.
Amazon: Kindle safety and named power-adapter energy-efficiency information: Power Adaptor Energy Efficiency Information: named supplies list 100-240 V AC, 50/60 Hz, 5/9 W DC output. Other Safety Considerations covers charging precautions. FOR CUSTOMERS IN JAPAN separately instructs 100 V AC; preserve that market restriction. This does not establish all Kindle/Kobo supplies or category grounding.

FAQ

Is my e-reader (Kindle / Kobo) dual voltage?

Check the actual input label on your e-reader (Kindle / Kobo) or its power supply. A 100-240V range covers those voltages; confirm frequency, grounding and model instructions separately. Category examples do not verify your own unit.

Can I use my e-reader (Kindle / Kobo) in Europe?

Only when the actual input rating covers the destination voltage and frequency and the plug fits with required grounding. For a medical device, confirm the exact supply and accessories with its manufacturer.

Do I need a voltage converter for my e-reader (Kindle / Kobo)?

Safety check: a plug adapter only changes plug shape. It does not convert voltage, so confirm your device label before buying.

Shopping links never change the safety verdict.

Guidance only — not professional electrical advice. Always confirm against your device's label before plugging in. Local wiring (especially in hotels and older buildings) can vary.
