Every affected phone was built for the Chinese market. So what actually happened? The story starts with an update. In August, Google … Read more
A Chinese charger plugged into a US outlet does one of two things, and the label on the brick tells you which. If it reads 100-240V and 50/60Hz, you need a small plug adapter and nothing else. If it reads 220V only, that adapter will do nothing useful. The distinction matters because adapters get sold … Read more
You can import a Chinese car into the United States. You just have to wait until the 2040s. That is the honest arithmetic behind the 25 year rule, and it covers every electric sedan built in Shenzhen or Shanghai. Two-wheelers are a different story.

One in six American households is behind on its electric bill. That is a Consumer Reports figure from late 2025, and it predates the current round of rate cases. In the first half of 2026 alone, utilities asked regulators for $18.6 billion in increases. The whole of 2025 was $29 billion. Almost all the attention … Read more
Last December, a strange phone went on sale in China. It could open your apps, find the right buttons, tap them for you. Here was an AI assistant that could actually control your phone. Only 30,000 units existed. They sold out in 48 hours, and resellers soon asked around $1,110 for a phone that retailed … Read more
Honor published a battery spec sheet this week that reads like a typo. The Magic9 Super Edition, arriving September 28, carries an 11,000mAh battery in a body 8.1mm thick that weighs 227 grams.
