I’ll travel to continental Europe + UK this summer. Looking for the most compact USB charger. 20W is more than sufficient. USB-C preferable.
The Mu One international was great, but no longer available. What’s best now? (the most common approach seems to be to purchase country-specific adaptors. That would make sense for the US-EU — I have a small folding Anker US — but I cannot find a folding US-UK adaptor.)
