Key Features & Typical Use
Fast Charging as a Room Category Feature
Although hotels categorize their rooms according to the family details visible in the first 10 minutes, speed of charging is now considered in classifying guests. Just consider the difference between a 20W plug in top hotel room and the regular charging system used in cheaper hotels.
The Device the Guest Actually Brought
Today, people come with smartphones, tablets, watches, and other devices. However, the sockets are not available for charging their devices simultaneously. Fast charging outlet cannot be used in connection with regular plugs or cables meaning that fast charging socket has a 20W output capable of charging the device faster than standard outlet.
Specified Once, Standardised across a Brand
It is evident that stating category instead of site helps when a business has more than one site. The two versions of 5 volts 2.1amps and 20 watts have the same casing, panel, and frame. Therefore, the upgrade will show as a single line in the schedule instead of a new product line, and whenever replacements are needed sometime in the future, they will belong to the same product line.
Proportionate on a Wide Plate
Generally speaking, the fast charging sockets become necessary at the closest positions with reference to the interior, i.e. they are not in the vertical position on their own. The dimensions of the plate of 86 x 76 mm enable it to be seen together with the other equipment of the room and to harmonize with the neighbouring equipment.

SD3B-019 – Tiering a Property by Charging Speed
As soon as a hotel offers two types of rooms, each criterion can be used to distinguish one type of room from the other. Charging speed is an effective factor as it is low-cost and easily distinguishable: different rooms are fitted with identical sockets and panels and require the same amount of time for installation while the expensive room offers only 20W charging circuits.
From a commercial viewpoint, the unit ensures that the standard is upheld over time. This occurs because the quick and ordinary charge types stem from the same cabinet and panels. Consequently, after five years the system can be modernized in a property without any change of size and of the finishing of the plates. The equivalent model in France from the viewpoint of the company operating in the French standard market is SD3B-021.

Frequently Asked Questions
Why specify 20W charging in a hotel room?
Charging speed is a factor that a guest observes as soon as he arrives, and it can be a distinguishing factor between types of rooms at a nominal cost. The module works the same way as a standard socket in terms of panel, box and circuit, so the upgrade is essentially only a line on the schedule and not an installation.
How does it differ from the standard charging version?
The charging output alone is sufficient. SD3B-018 has an output of 5V at 2.1A, while SD3B-019 has an output of 20 watts. Furthermore, the connection point, casing, face and frame have been designed in a similar way so that both categories can be manufactured from one product line.
Can the socket be used while devices are fast charging?
Indeed, the charging system can function free from the mains outlet; this means any device can be plugged into the standard Schuko plug at the same time when any of mobile phones and tablets are connected at the USB ports.
Is the French format available at 20W?
Certainly, SD3B-021 delivers the French Type E outlet with USB-A and Type-C at 20W in one panel of 86 x 76mm, thus helping companies work with the same charging levels from both outlets efficiently.
Does fast charging need a different wall box?
Module employs the conventional installation position for the series. Confirm the box depth on site for locations with charging sockets in case of large installations and approach us for dimensions if necessary.
Can the property be supplied with both tiers in one order?
It is true. The two different charging types as well as the simple socket are designed in a single way, so the entire property schedule may be provided at once in which different charging types are separated only by the room classes.
