- •AC prongs sometimes feel loose in the wall outlet; charger’s dense and heavy design can make it less stable unless plugged in with prongs facing up.

Bottom Line
The MUNBYN CR14 140W USB-C GaN Wall Charger is a compact, powerful, and flexible charging solution ideal for travelers and users juggling multiple devices. It charges quickly, intelligently manages power, and handles a range of USB-C devices well. However, serious caution is advised due to overheating and safety concerns under heavy or extended loads, so it’s best suited for intermittent use and careful monitoring. If you need a similarly compact, high-wattage charger without the heating issues or plan on frequent multi-device simultaneous charging, consider exploring other premium GaN chargers specifically engineered for sustained heavy use and stable outlet fit.
