We’ve seen frequent leaks regarding the Samsung Galaxy S10‘s reverse wireless charging feature, supposedly dubbed PowerShare. Now, an FCC filing has seemingly established details regarding the feature.
The filing, spotted by XDA-Developers, reveals that the phone is capable to produce “a maximum power of 9W.”
“The EUT [test device – ed] can be configured to receive or transmit an AC power indication through magnetic induction (MI) or magnetic resonance (MR). The operating frequency range is 110 –148kHz and can create a maximum power of 9W,” reads the full extract of the FCC report.
What does this actually mean?
If the nine-watt figure is certainly true for reverse wireless charging, this means the Galaxy S10 can charge up other devices at an exponentially faster rate than the Huawei Mate 20 Pro. According to our own testing, Huawei’s flagship tops out at a stingy 2.5 watt when charging other devices. This is well under the baseline five-watt charging speed you can imagine from inexpensive wireless chargers, let alone today’s fast wireless charging pads.
There is a chance, however, that this stature doesn’t reflect real-world results. We could be looking at the theoretical maximum charging speed for test units, while Samsung decides to limit the charging rate for whatever explanation (e.g. safety). In any occasion, cutting the charging speed in half would still produce much faster results than Huawei’s device.
In other words, if you desire to provide some juice to your friends, it looks like the Galaxy S10 might be the faster, more suitable solution. But we’ll need to wait for February 20 to get official confirmation of the feature and its details.
The FCC filing also supposedly shows that the Galaxy S10 will support Wi-Fi 6 connectivity (802.11ax), which is the newest and greatest Wi-Fi standard. The new standard offers faster speeds, higher capacity, and superior power efficiency, but you’ll want a compatible router to make the most of it.
