Four-port 20W charger set

This pack contains four white REKNA OFS-391 wall chargers, each with one USB-C and one USB-A port delivering 20W total output. The set suits households or travellers who need simultaneous charging for phones, tablets, headphones or smartwatches across multiple rooms or bags. It is not for buyers who require higher wattage for laptops or single-port fast-charging protocols beyond the stated specification.

Replaces older 5W bricks

Each unit provides up to three times the output of a legacy 5W adapter, cutting typical phone charge time to roughly 30 minutes for 50% capacity. The upgrade is worthwhile when daily routines demand quick top-ups for several devices at once. It does not suit users who need Power Delivery profiles above 20W or dedicated single-port chargers for maximum speed on one device.

Plug-and-play with dual-port sharing

Simply connect each charger to a 110V socket; the built-in smart chip allocates current between the two ports automatically when two devices are attached. The main issue arises if both connected devices draw near the 2.2A limit, causing the charger to throttle output to stay within its 20W ceiling. No configuration or driver installation is required.

Questions about this item

What type of wall outlet does the REKNA OFS-391 plug into?

The charger plugs directly into a standard 110-volt AC wall outlet using its built-in folding prongs; no separate cable or adapter is needed.

How do I install the charger and what is the common mistake?

Insert the prongs fully into the outlet until they click, then connect your cables; the common mistake is leaving the prongs partially folded, which prevents proper contact.

When should I replace one of the four chargers in the pack?

Replace a unit if it no longer delivers the 20W output, if the USB-A or USB-C port feels loose, or if the housing shows cracks or discolouration from overheating.
