The Samsung Galaxy S21 comes without a charger in the box, but that doesn’t mean you have to buy one to be able to charge it fast.
The Samsung Galaxy S21s come without a charger included in the box. That, however, does not mean that you have to buy a new one to take advantage of the fast charging included in the new terminals.
Since Samsung has been betting on USB Power Delivery technology for some years to give life to the fast charging systems of its terminals, it is possible to use old chargers and those of other brands to be able to quickly recharge any of the three models of the Galaxy S21 series.
But keep in mind that not all chargers work, since the new S21 support is introduced for the system called USB Power Delivery Programmable Power Supply, or USB PD PPS. For this reason, today we wanted to review the requirements that chargers must meet to be able to recharge the models of the family taking advantage of their fast charging technology, as well as giving you some affordable options available on the market.
This is the fast charge of the Galaxy S21
First of all, it is worth reviewing the more technical aspects of the fast charging system included in the company’s new terminals.
And it is that this year Samsung has decided to reduce the maximum charging power supported by its S21 series devices, from 42 to 25W. Thus, although it is far from the maximum levels of the industry, the company ensures greater durability of the batteries, as they are subjected to less stress and therefore do not suffer less degradation.
The fact of using the USB Power Delivery Programmable Power Supply system means that the phones can also be charged through those chargers that support the Quick Charge 4+ standard. In more technical terms, the terminals and the charger “negotiate” a load of about 2.6 amps at 9.3 volts to produce the 25W power.
Of course, Samsung offers buyers of the Galaxy S21 the possibility of buying, separately, chargers compatible with the fast charging system of the Galaxy S21 and S21+, and of course the Samsung Galaxy S21 Ultra.
These chargers can be found in stores such as Amazon, at a price that ranges between 19 and 30 euros depending on the model chosen.
If at the time you decided to buy a Galaxy S20, Galaxy S20 Plus or Galaxy S20 Ultra, or one of the models in the Galaxy Note10 or Galaxy Note20 series, and now you have leaped to one of the company’s latest terminals, you can continue to use the charger included with any of these terminals to quickly charge your new S21.
Instead, as explained in Android Authority, the charge will be reduced to a power of 15W if you use an older Samsung fast charger, such as the one included with the Galaxy S10.
The same happens with the rest of the USB Power Delivery chargers of other brands. In most cases, the charging speed will be reduced to 15W if the charger is compatible with USB PD 2.0 -such as the one included in the Google Pixel or Xiaomi’s 30, 40, and 120W chargers- -, or 9W if the charger does not have support for this technology.
The main problem appears when using chargers that use fast charging systems from other manufacturers, such as Warp Charge from OnePlus -in its old editions since the current ones have support for USB PD-, or VOOC technology from realme and OPPO. In that case, we’ll see the charging speed drop to as low as 0.5W, making charging times frustratingly slow.
What about third-party chargers?
In the market it is possible to find a large number of mobile chargers from third-party brands specialized in this type of accessories, such as Belkin, UGREEN, Anker, and RavPower, to mention just a few of the most popular.
Most chargers from these companies already include support for USB Power Delivery technology, however, unless they also include support for USB Power Delivery PPS, the charging speed on the Galaxy S21 will be reduced to 15W.
Unfortunately, there are not many third-party chargers that support this technology at the moment, so buyers of the new Galaxy S21 will find themselves in the situation of having to buy one of the official chargers if they want to charge their devices at the maximum possible speed . . Otherwise, you will have to settle for the 15W of charging that other USB PD chargers provide.
