Looking for a super fast charger for my s21 ultra, they recommend 45 watts.
Any advice in which one perhaps on takealot?

Thanks in advance

Check the Huawei store. They usually have a few good chargers

I read that the s21 doesn't work with the 45watt charger. Will look for article

Galaxy S21 charging speeds: Which models support 45W charging?

Of the Galaxy S21, Galaxy S21+ and Galaxy S21 Ultra, which of three new Samsung flagships have support for 45W fast charging? Here's the answer.

Huawei P40 Lite 5G has a 40W charger did not know there is a 45W charger. At 40W it charges from 0 to 100 in less than 1 hour.

Nice way to kill your battery.

My phone can do 19% to 81% in 1h using a 1.5A charger.

S21 only supports 25w charging.

Samsung only supports Samsung chargers for optimal charging. You won't get more than 18w charging from a Huawei charger

Well who to believe? Because according to Samsung it does support Super Fast and its rating is 45w

Well then why would the manufacturer suggest it?

Just no, battery won't really have much difference in wear and tear if you up the power if it's at a low percentage/below 50/75% and your phone and charger will negotiate in regards to power draw to make sure it handles it correctly.

A conventional charger has an output of 5 to 10 watts. A faster charger can improve that by up to eight times. For example, the iPhone 11 Pro and Pro Max come with an 18-watt fast charger, the Galaxy Note 10 and Note 10 Plus have 25-watt chargers in their boxes. Samsung will sell you an extra-speedy 45-watt charger for $50.

Unless there's some technical flaw with your battery or charger electronics, however, using a fast charger won't do your phone's battery any long-term damage.

Here's why. Fast-charging batteries work in two phases. The first phase applies a blast of voltage to the empty or nearly empty battery. This gives you that blazing charge of from 50% to 70% in the first 10, 15 or 30 minutes. That's because during the first phase of charging, batteries can absorb a charge quickly without major negative effects on their long-term health.

You know how it seems to take as long to fill up that last 20% or 30% of the battery as it does to charge the first 70% or 80%? That last part is the second charging phase, where phone-makers have to slow down and carefully manage the charging speed or else the charge process actually could damage the battery.

Arthur Shi, a tear-down engineer at the DIY repair site iFixit, suggests imagining a battery as a sponge. When you first pour water onto a dry sponge, it absorbs liquid quickly. For a battery, this is the fast-charging phase.

As you continue to pour water onto the increasingly wet sponge at the same rate, the liquid will bead up on the surface as it fights to soak into the saturated sponge. For a battery, this unabsorbed charge can result in shorts and other issues that could potentially damage the battery.

It was up to something like 50/60W is fine (Samsung's fast charge is conservative at 45W), those going above like OnePlus are using two battery cells.
