Apple today updated its online store to offer several new Mophie products, including the Powerstation Pro, GaN 120W Charger, and multiple car chargers.


Priced at $150, the Mophie Powerstation Pro offers 20,000mAh for charging iPhones, iPads, and other Apple devices. It offers up to 45W, so it is able to charge a MacBook Air, plus it can fast charge the iPhone and the iPad.

There are dual USB-C PD ports for charging two devices at one time, and Mophie says that it offers 72 hours of additional battery life on an iPhone and eight hours for a MacBook.


Available for $100, the Mophie Speedport 120W GaN Wall Charger includes three USB-C PD ports and one USB-A port for charging up to four Apple devices at one time. It provides a total of 120W, which can be split across the devices being charged.

A single device using the first USB-C port can access up to 100W, while two USB-C ports can provide charging power starting at 99W. It is made using Galium Nitride (GaN) technology to keep the size compact, and it comes with a 2m USB-C to USB-C cable.

Apple is also offering several different Mophie Car Chargers, all of which plug into the 12V auxiliary power outlet in a vehicle.
All of the new Mophie products can be purchased as of today, with most delivering by next week. Many Apple retail stores are also now offering these Mophie accessories.

How does 20,000mAh relate to Wh?

Do I have to suppose 5V, then 1A relates to 5W?

So 20,000mAh = 20Ah relates to 100Wh?

Use 3.7 volts for a lithium battery's average native voltage.

Some batteries are run at a higher voltage though, so you have to check with what the battery's design voltage is. For instance, the Magsafe battery from Apple ran at double the voltage so it had half the amp-hourage of its competitors but people didn't get that the voltage it's run at is double (though in fairness it was a bit small compared to competitors too, but it's a pretty slim battery with up to 15 watts of Magsafe charging capability when plugged in, no one has that in that compact a package).

This one is likely quoting its 3.7 volt nominal average. So it's 3.7 * 20 Ah = 74 watt-hour energy.

Amp-hour is kind of stupid as a system. Watt-hour is better, though joule is the "real" SI unit that should've been used originally.

I hesitate to order anything from aliexpeess.

I'm loyal to the Anker brand.
I buy from Baseus on Aliexpress because I'm in South America.

But if you are on US, you can buy it on Amazon:

Battery is a total rip off for sure. Best Buy just had a clearance on their 65W USB-C output (80W total) 28600 mAh for like $30. Unfortunately that one sold out. They also have an updated 85W w/ 65W+20W USB-C for about half this price.

65W 20Kmah

many more like this, I'm sure. But the 120W is pretty good.

here's a 120W one. There's also 30kmah 65w ones all under $100

Agree, Anker and Belkin chargers have been good experiences for me so far, as someone usually only ordering Apple branded charging equipment, due to concerns for quality and not overheating etc.

On my desk is my Mophie power bank that I bought in 2017. Still going strong, used the hell out of it. Sure, only two ports, but it's got PD so can charge my Macs too. Quality is great with Mophie!

Amp-hour is kind of stupid as a system

It's a measure of capacity regardless of voltage. It's useful in some areas like, say, RC hobbies, or places where we care about battery capacities if only in a theoretical sense. We use LiPo batteries (I build FPV quads for years now) predominantly and care very much about mAh values (and the TSA cares about their Wh values haha).

E.g. a 5,000mAh battery means "pulling 5,000 mA from this battery constantly for one hour will reduce its voltage to its nominal value". Similarly you could theoretically pull 1,000mA for 5 hours and reduce the battery to its nominal voltage.

Of course one needs to understand wtf an Ampere actually is for this to be meaingful, suffice to say "unit of electrical current".

So a 6,000mAh battery will have "more capacity" than a 5,000mAh battery -- assuming same operating conditions and without regard for their nominal voltages.

I feel usage of mAh is very much marketing tactic, similar to usage of "megapixels" and storage sizes that are base-10 instead of base-2. ¯\(ツ)/¯

Baseus has a 100W 20000mAh power bank:

This is pretty BA!
But man... That product video* featured on (U.S.) makes me want to not buy one. Just not sure why anyone would ever feel compelled to spin around, in slo-mo, in a light breeze, whilst carrying their portable charger. 😂

* the video is kinda awesome...

Are these good or bad? I’ve no idea. Gan? PD? Outputs? I haven’t got a clue. How I long for the days when you just bought a charger and it worked. How fast do people need to charge stuff?

Midwest America.
Worst Try is advertising a Mophie batt pack with jumper cables? Wow...

It's the: 'mophie - Powerstation Go Rugged AC Portable Power with AC Outlet, USB-A Ports, Floodlight, and Jumper Cables - Black'

USB-A is so hard pass, and floodlight is so gimmick, but jumper cables? That's so McGyver-ish... :D:D:D

This model detailed here sounds more usable. But jumper cables...
