Travel Adapter Not Working? Fixes (2026)
Why your travel adapter is not charging and how to fix it: blown fuses, loose recessed sockets, and voltage mistakes.
A travel adapter that is not working is usually suffering from one of four problems: a blown fuse, a plug that is not fully seated, a voltage mismatch, or overloaded USB ports. Work through these fixes in order before buying a replacement.
No power at all from the adapter
Check the fuse first. On the Epicka, slide out the fuse holder and inspect the 10A fuse; replace it with the included spare if the filament is broken. Then verify the wall socket itself has power by testing it with the hotel lamp. Some European hotel rooms cut outlet power when the key card is removed from the wall slot, so confirm the room power is actually on.
Adapter works but sits loose and cuts in and out
Reseat the plug fully. France's recessed Type E outlets and older UK sockets reject shallow plugs. Push the adapter in firmly until it sits flush; if it will not seat, the plug type is wrong for that socket and you need a different slider or piece. Never wedge a loose adapter with paper or tape, intermittent contact causes arcing.
Device plugged in but not charging, or charges very slowly
Check for a voltage mismatch and USB sharing. If a 120V-only appliance is plugged into 240V through an adapter (not a converter), unplug it immediately and do not retry. For slow USB charging, unplug other devices; total USB output is shared, and four devices at once divide the available amperage. Charge the phone alone first to confirm the port works at full speed.
Adapter gets hot during use
Reduce the load. Mild warmth is normal; uncomfortable heat means you are near the wattage ceiling. Unplug high-draw devices and check the total against the rating (2,500W at 250V for most all-in-ones, 250W for the Bestek's converter stage). If it is hot with only phones plugged in, the unit is faulty, stop using it and replace it.
Questions, answered
My adapter sparked when I plugged it in. Is it broken?
A tiny spark on insertion is normal, especially on 240V grids; it is the capacitors in your charger filling. A loud pop, visible scorch marks, or a tripped breaker means something is wrong: check the fuse, verify the voltage match, and do not reuse a scorched adapter.
The hotel bathroom has a shaver socket. Can I use my adapter there?
Shaver sockets are low-power isolation transformers meant for electric shavers, usually rated around 20W. Do not plug a multi-device adapter into one; you will trip its protection or overheat it. Use a proper wall outlet.
