Indoor Charger 4smarts 546020 Universal White AC Fast Charging

The 4smarts 546020 Indoor Charger is a compact universal AC charger with one USB-C and one USB-A port, designed for fast charging of smartphones, tablets and accessories. Its angled, slim housing reduces strain on cable connection points to protect cables and allows placement in tight spaces thanks to a 1.5 cm depth. The charger supports an input range of 100–240 V and delivers up to 12 V output, with GaN technology for improved efficiency and lower heat generation.

Advantages

The angled housing protects cables from bending and wear when plugging and unplugging, extending cable life and improving user comfort. The flat design barely protrudes from the wall, making it suitable for sockets behind furniture and for travel thanks to a fold-out US plug and an EU adapter. Dual ports (USB-C and USB-A) provide flexible simultaneous charging of two devices, while GaN technology keeps the unit compact and energy-efficient. Built-in safety features prevent overvoltage, overheating, overcharge and short circuits.

Suitable for

• Charging smartphones and tablets at home or in the office
• Powering accessories such as TWS earbuds, power banks and older USB devices
• Use in tight or hard-to-reach sockets behind furniture

How to use

Plug the charger into a compatible AC socket (100–240 V). Connect devices using a USB-C or USB-A cable; both ports can be used simultaneously to charge two devices. When travelling, unfold the US plug or attach the EU adapter as required for the local socket. Ensure cables are inserted straight into the angled housing to minimise strain on connectors.

Recommendations

Use certified cables and avoid exposing the charger to liquids or extreme temperatures. Disconnect the charger from the socket when not in use for extended periods. If a device or cable becomes unusually hot or charging is inconsistent, stop use and inspect cables and ports.
