SAMSUNG 25W Wall Charger USB C Adapter, Super Fast Charging Block for Galaxy Phones and Devices, Cable Not Included, 2021, US Version, Black

This fast charger wall adapter is very durable and provides fast charging 25w charging speeds to my Galaxy 23. It is a little less compact than typical wall adapters as it provides more rapid charging power, but it does the job well. It does get warm after a full phone charge but nothing close to "hot". I've got 2 now and don't think I'll ever go back to regular charging speeds.Note- you will need to ensure the cord you are using is compatible for 25w charg8ng speeds. This does not come with a cord.

I really want to give this three or four stars instead of five, because I'm desperate for a charging block that works with all my Samsung devices, but is a little more narrow, or a little flatter against the wall, and has the USB hole on the side instead of the back. But I can't find anything that meets those criteria. Much less charges it quickly.So, this official Samsung block actually charges very quickly, to both of our Samsung phones and our Samsung tablet. I'll be honest I had been using my old Motorola chargers, but they're finicky and don't work with Samsung so well. I can't explain the science on that, but it made me seek out official Samsung blocks.I can't hold against this block it's shape or its size, I can't dock at stars because it's exactly what it represents on the description. So me wanting to take away a star or two is simply because of my own hopes and expectations for what I can find. That wouldn't be fair though. This block is exactly how it is presented, and it works great. So I really have no choice but to give it the five stars. And for that matter, especially considering it's an official Samsung charger, it's super well priced. I was surprised about that. So I purchased two separate orders over the last month, for a total of four. And I'll probably get more soon.Cheers!

A LOT of people don't realize that to use the fast charge feature on your Android cell phone, you need to have the stars aligned properly or it won't work properly & you won't necessarily know that it isn't because your phone still charges albeit NOT as fast.My Samsung Galaxy S20+ will charge with a regular 15 watt charger box, but it will NOT be using the fast charging system to charge it!!!With the S20+ you need the correct charging box & the correct charging cable!This 25 Watt wall charger works & I bought a 'Type C' charging cable to plug into this. The cable supports up to 100 watts which is well beyond the 25 watts that's needed. Buying the 45 watt wall charging unit has been shown to give ZERO added benefit so save your money & get this 25 watt device.Inside my phone I need to turn on the 'super fast' charging option & the fast charging kicked in. I was able to go from approx 90 mins from near 10% to full & it got cut to 50 minutes.This cut 40 minutes off my time from 90 mins which is about a 50% reduction in charging time. Imo this is WELL worth buying this charging box to receive benefit.

Been using these for over a year and has been not only reliable but FASTER then a normal charger.

The charger supports fast charging for any samsung phones. I bought it for replacement of my charger. It has worked great and still working.

Works very well with my s21. It charges super fast. It doesn't charge my tab a8 very well. It recognizes the charger but charges slowly, and after 5-10% of charging it stops. Then I have to unplug and replug too continue. Just weird considering they're samsung products

Cable is sturdy. It holds up to light abuse of being in a backpack pocket daily and still looks pretty new after months. I don't mind the shorter cord length as i rarely use my phone during fast charge. I'm sure since its name brand its not the cheapest option available but i like the piece of mind that its meant for my device.

I have the Samsung Galaxy S22. It, as well as other cell phones calls for a 25W charger. If you buy a non-Samsung brand you want to look for the following features: PD (Power Delivery), PPS (Power Programming Supply) compatible, and QC (Quick Charge) at least 3.0. QC 4.0+ is backwards compatible to 3.0. Power Delivery is a handshaking protocol where the device and charger communicate and determine the optimal charging rate. Also, the latest iteration of PD, Power Delivery 3.0, enables a feature called Programmable Power Supply which further enhances the efficiency of power delivery without sacrificing your batteries' longevity. I believe it also keeps the phone from overheating while charging. If you buy a 25W Samsung charger you don't have to worry about the prior info. It's all built into their charger. If you want a smaller charger search for GaN charger. Gallium nitride charger allows for smaller chips, creating a charger small enough to keep in your pant pocket.The last piece in the puzzle is a high-quality USB-C cable. For charging beyond 60W, you’ll need to make sure you’re using an electronically marked, or eMarked, USB-C Power Delivery cable. This is important to keep in mind when charging larger devices such as laptops. You will also find that USB C charges faster than USB A. The reason is USB-C 3.0 cables are designed to carry more power than previous versions of USB, which maxed out at 7.5W. The cable I just bought is KUYIOHIFI USB 4 Cable Compatible with Thunderbolt 3 Cable 100W 5A/20V USB 3.2 Fast PD Cable E-Mark. I hope this helps.
