Best 45W Chargers For Galaxy S20: Samsung took multiple additional steps in the way that it handles high-speed charging to secure overheating and long-term battery damage. Unfortunately, those steps are a series of hoops that accessory makers and users like you and me have to move through when we like to charge our S20 Ultra at top speeds.

45W Charging Setup:

However, to get 45W charging, your setup requires the following:

  • A USB-C Power Delivery 3.0 charger that supports:
    • PPS (Programmable Power Supply): this is a subsection of Power Delivery 3.0, and there are some chargers out there to support it so far.
    • 10V/4.5A charging speed
    • PDO (Power Delivery Objects): PDO negotiates the voltage/speed between the charger and the phone. What it makes the difference between your S20 Ultra getting the more standard 10V/3A and 10V/4.5A from a charger.
  • Also, an e-marked USB-C to USB-C cable

Due to these particular requirements are only used by two devices now — earlier only one device over the last six months. However, accessory makers have had little reason to support a non-standard charging profile. You’ll view many chargers on Amazon that say they’re PD 3.0 (PPS2.0). But they can’t support PDO or the 4.5A charging speed and thus, can’t get full 45W charging.

I really like to sell you more travel-friendly 45W chargers for the S20 Ultra, really. Also, I’m so boring who enjoys finding the best quality and amazing features in a charger. But for the Galaxy Note 10+ and Galaxy S20 Ultra, there’s nothing but heartbreak to be found out there right now beyond some car chargers and power banks. Yet I’ve come across a 45W non-Samsung wall charger for the Note 10+ that actually hit 45W. Also, there’s been little progress since its release.

Why 45W won’t matter for most of us anyway

Charging a 3,500mAh Note 10+ from empty to full takes 55-58 minutes with the 45W charger. However, charging the same phone with the 25W charger comes with the Note 10+ and with the S20 Ultra, it takes 65-70 minutes. However, the major reason for this is that like all chargers. You only get the maximum speed during the few minutes while the battery is almost empty. When the battery refills, the charging speed gets slower and slower to secure your phone from overheating. However, it’s also better for the battery long-term.

You’ll only view 45W with an almost-dead S20 Ultra.

This variable in speed means that once you arrive about 55% charged, you’ll view approximately the same charging speeds on the 45W charger and 25W charger. So if you have a 40-50% battery left whenever you plug back in between work and your dinner date. However, you can’t get the full advantage of the charger. Nor will you view significantly shorter charging times compared to the in-box 25W charger.

Also, we know that the Galaxy S20 Ultra has a 5,000mAh battery. The battery is significantly bigger than the 3,500mAh Note 10+. So the time difference between 45W charging and 25W charging will be quite bigger than the 10-minute gap we view on the Note 10+. However, as the bell curve for charging speeds perform the same on both devices, I’m still not expecting to view more than a 25-minute difference between the 25W and 45W charger from empty-to-full. That’s might not going to be worth the additional $40-50 for a wall charger.

Where you view the real advantage of 45W charging is on-the-go. In those cases, having a 45W power bank could be worth its weight in gold. Unlike wall chargers, there aren’t so many power banks that will charge the S20 Ultra and Note 10+ at 45W.

If you’re usually only down to 30-40% when you recharge your phone. However, the 45W charger will barely be faster since that full speed is only employed at the start of the recharge cycle. In that instance, you might be stick with the 25W charger that was included in the box with your S20.

As mentioned earlier, Elecjet offers two USB-C Power Delivery power banks that can charge the S20 Ultra at the speed 10,000mAh model. However, still limited to Indiegogo and a larger 20,000mAh model out for a while and is available on Amazon. Besides the vendor difference, the 20,000mA model makes more sense from the capacity and pricing perspective. The PowerPC is cheaper and can recharge the S20 Ultra four times before it runs dead.
