INIU Mini USB C Charger, 30W GaN Fast Charging ETL Certified Wall Adapter Block

4.3

$10.99as of Jul 7

The INIU 30W Mini USB C Charger delivers fast, safe charging with its GaN IV technology and ETL certification. Reviewers noted its compact design that saves outlet space while enabling simultaneous charging of two devices. The charger includes two 5ft cables and is suitable for iPhone 17, iPad Air, and other USB-C devices. Some users reported warmth during use, which is normal but may affect charging speed in high temperatures. It's ideal for travelers or those needing a space-saving solution, but not optimal for users requiring maximum charging speed from both ports simultaneously.

Strengths

— ETL-certified safety with GaN IV technology that keeps temperature 50°F below 170°F during charging

Watch-outs

— Charger gets warm during use, which is normal but may trigger protection mechanisms in high-temperature environments
— When both ports are used simultaneously, total output is shared and charging speed per device is reduced

How they stack up

120W USB C Charger Block with 2 Built-in Retractable Cables,4-in-1 GaN IV Foldab

The Betrusami 120W charger offers the highest wattage and built-in retractable cables, but it lacks customer reviews and detailed warranty information, unlike the Anker models which provide proven reliability and brand support. While it's more feature-rich in terms of cable inclusion, it's less tested in real-world usage compared to the Anker Prime 100W charger, which has established performance and safety standards.

INIU Mini USB C Charger, 30W GaN Fast Charging ETL Certified Wall Adapter Block

The INIU 30W charger is more compact and includes cables out of the box, but it delivers significantly less power compared to the 67W and 100W Anker models. While it's suitable for smaller devices and travelers, it doesn't match the power efficiency or portability of the Anker Prime 100W charger, which offers better performance for demanding devices.
