DEVIA Allen Series QI Wireless Charger (Black) (EA242)

Description

The DEVIA Allen Series QI Wireless Charger (manufacturer reference EA242) in a black finish (V3) is a professional-grade ultra-thin induction charging station, specifically configured for corporate office layouts, reception desks, technical workbenches, and B2B resale. Designed in a compact and sleek pebble format, this wireless charger eliminates mechanical wear on smartphone charging connectors (USB-C or Lightning) by utilizing the universal Qi magnetic charging protocol.

In terms of electronic engineering, the third revision (V3) of the Allen Series stands out with its intelligent controller capable of dynamically adjusting its wireless output power according to four energy profiles: 5W, 7.5W, 10W, and up to 15W maximum. This versatility ensures perfect software and hardware compatibility, whether charging Apple iPhones (capped at 7.5W on standard protocol) or Android flagships utilizing higher tiers of 10W and 15W. The electronic circuit manages a transmission distance of 6 mm, allowing induction charging to be initiated through the thickness of common protective cases on the market.

The chassis features an ultra-flat design (only 12 mm thick with a 98 mm diameter) with a workshop-grade matte black finish. The base incorporates a passive thermal management system to stabilize charging efficiency at a nominal rate of 70%, while protecting client device batteries against excessive temperature rises.

Workshop Advice & Usage

To utilize the full 15W charging power of your Devia EA242 pad and avoid malfunctions in the workshop, the choice of the upstream mains power adapter is crucial. Do not connect the charger to a simple PC USB port (limited to 500mA) or an old 5V/1A charger, as the pad will enter safety mode or charge at an extremely slow speed. You must imperatively pair it with a mains wall charger compatible with Quick Charge 3.0 or Power Delivery delivering at least 9V/2A or 12V/1.67A. Critical workshop safety rule: Inform your clients that no metallic parts (adhesive plates for car mounts, finger rings, credit cards, or aluminium-shielded cases) should be on the back of the smartphone when placed on the pebble. The presence of metal would trigger immediate overheating via eddy current (direct induction effect on the metal), which would force the charger circuit to cut the charge to avoid damaging the device battery.
