Buying a new phone charger can be misleading. It's usually good to use what comes with the device, but it's probably not the adapter that provides the fastest and best charging speeds. These are often more expensive, and your smartphone manufacturer will not be so generous from the very beginning.
This is the case with the upcoming Samsung Galaxy Note 10+, which supports a powerful 45 W charging – even if the power supply provided with the device will generate a maximum of 25 W. It is still quite great, but it is not as fast charging as you could get.
What's frustrating – even for Android Police, which recently tried to make recommendations for chargers used with the Galaxy Note 10 + – is that third-party chargers may look as if they were loading at the fastest speeds that a smartphone can handle. But as it turns out, this may not be the case when you connect a telephone.
In the case of the Galaxy Note 10+, this means that third-party chargers that claim to charge at 45 W + and support version 3 of the USB Power Delivery standard (15 volts and 3 amps) may still not provide the fastest expected charging speeds. As described by Android Police:
"One obstacle, according to the Chinese technology blogger Ice Universe, is whether your charger supports a programmable power supply or PPS – this allows the charger to output alternating voltage instead of the typical constant levels of 5 V, 9 V, 15 V, and so on. The point is that chargers may be PD3.0 compliant, but choose to use constant voltages instead of PPS. "
In other words, buying the perfect charger for your device will be annoying at best:
I support this recommendation. If you absolutely need to charge 45 W for the Galaxy Note 10+, you should choose the expensive Samsung charger (50 USD). Otherwise I wouldn't order a cheaper charger conceited will provide you with the expected high speeds. Wait for more people to get the Galaxy Note 10+ (from August 23) and actually test different third-party chargers before you buy them. This is the best way to ensure that the products you buy are fully compatible with the fastest charging your device.
Consider also carrying out your own tests with any charger. You should be able to go from empty to full charge in less than an hour – or at least faster than about an hour and five minutes that you'll need to fully charge your device with the included 25W charger:
And don't forget: this 45 W charging speed is only supported by the Galaxy Note 10+, not the Galaxy Note 10. If you have a slightly smaller version of the latest Samsung smartphone, stick to the included 25 W charger – this is the best charging speed you'll get.
