We tested 20 wall chargers, from cheap to expensive, to see what we would find - from 15-140W, with screens and without, to arm you with the knowledge to pick a good one out of a sea of mediocrity
The article details testing of 20 wall chargers with varying wattages, features, and prices to help consumers choose effective and safe charging solutions. It evaluates technologies like GaN, USB-PD, and PPS to determine real-world performance, efficiency, and device compatibility. The findings aim to cut through market clutter and inform buyers about value, safety, and optimal charging capabilities.
- ▪The test included 20 wall chargers ranging from 15W to 140W, assessing output, efficiency, heat management, and safety.
- ▪Technologies like GaN, USB Power Delivery (PD), and Programmable Power Supply (PPS) improve charging speed, efficiency, and thermal performance.
- ▪Most modern devices are protected against incorrect voltage or overcharging, reducing the risk of damage from using non-original chargers.
- ▪Higher-wattage and feature-rich chargers often come at a premium price due to advanced materials and safety protocols.
- ▪GaN-based chargers offer higher power density and smaller size compared to traditional silicon-based models, with improved heat management.
