I don't know that "future proof" really applies here. Although newer phones can take advantage of faster chargers, older chargers are not any less capable. It looks like a 7th gen iPad from 2019 had an 8,800 mAh battery while maxing out at 12 W charging. The current iPhone 16 Pro Max has a battery about half that size, and we're talking about 20 W charging on this deal.

Also, look at the charging graph near the bottom of this page [chargerlab.com]. It shows the iPhone 16 Pro Max only charging at 28 W for about 13 minutes before dropping down to about 22 W. And by 30 minutes, the phone was only charging at 15 W. When going from 0% to 100%, 50% of the capacity and about 80% of the time is charged at 15W or below.

In most cases...

If you are the kind of person that normally lets your phone drain most of the way before charging, and you need a significant boost to get you through the day, then it's worth focusing on maximizing your charger.
If you normally charge you phone when it's above 20% or 30%, like plugging in while commuting or using a wireless charger on your desk, going beyond 20 W usually has greatly diminishing returns.
If you normally just need to charge your phone while you sleep, even a 5 W charger would probably work just fine.

TL;DR: 20 W chargers should be helpful for phones and tablets for a long time. You mainly need to look into higher wattage chargers when dealing with higher draw devices like laptops.

P.S. I'm not trying to discourage anyone from using more powerful chargers. I'm just trying to dispel the myths around needing them. Splurging on a charger is great. But so is getting a handful of inexpensive 15W+ chargers to have convenient around your home or to bring on family trips.

That doesn't mean you have to charge at that speed.
Slower is better for the battery anyways

Good for back ups. Too bad it's not a smaller size like the GAN ones.

20W for under $4. That is the output of the new iphone 16 pucks. Not the worst deal, Im in for a couple.

20 watts is plenty for many people and these are quality chargers. If I didn't already have them I'd be ordering them.

While these are fine for the base models of the iPhone they may not be future proof since more devices are exceeding the 20W charging speeds . For example base s25's are 25W while ultras are 45W. iPhone 15 and 16 pro max top out at 27W while the pixel series range 27w-37w for the pixel 9 series . Motorolas can charge up to 65w for US based devices . There are other phones out that charge at 100+w . Not a bad deal if you want a reputable brand and don't need the fastest charging

These came with the otterbox magnetic chargers that I bought a year or two ago, and every single one (5) of these wall bricks died within a week. I'll never buy another otterbox product again. Avoid this product specifically, it's pure garbage.

They weren't separate transactions. They were all purchased at one time to have wireless chargers in each room of our house.

It's PD-only, no PPS. Probs will see 1/2 charging speeds on Samsung devices.
