Hands-On With Anker's MagSafe-Compatible Battery Pack

I really don't see the point of these. Usually with a portable power bank, I want minimize the time spent using it and thus charge as fast as possible. Thus those with 18W PD are appealing. Plug in, charge up for 15-30 minutes, and put it away. In and out, fast.

For this, I think the PowerCore 10000 PD Redux is the best bang-per-buck right now. It's small but packs 10,000mah and 18W PD. It can take an iPhone from dead to >50% in about 30 minutes.

But at 5W, it would take many hours to get a reasonable charge - to say nothing of the inherent power loss of wireless. What's the point?

I am very interested in what / if apple does a smart battery pack for magsafe.

I think the big appeal here is that you're not tied down with a cable and a big heavy battery. You can continue using your phone as normal while charging with this device.

Most people like it because it has more Watts than an average Apple Power Adapter at the same exact size. But I could still mind a bigger Power Adapter.

How do you figure? It charges at 5W, which is equal to Apple's lowest-wattage charger.

But it's not THAT small. Anker makes chargers equally small and just about as light that both pack more power and charge faster. And anyway, I think the best way to use your phone as normal is to charge it as fast as possible and then put the charger away. In other words, charging for 15-30 minutes and then using the phone as normal is better than using the phone as normal with this brick attached for 3 hours.

The key here is power loss due to wireless. Even though this things packs 5,000mah, Qi has a power loss of almost 50% ('https://debugger.medium.com/wireless-charging-is-a-disaster-waiting-to-happen-48afdde70ed9'). So only approximately 2,500-3,000mah are actually reaching your phone, and the rest is wasted to heat. You might as well get a 3,000mah power bank the size of a chapstick and use a cable - it will be lighter, smaller, and equally effective. Or, alternatively, get a 5,000mah power bank of equal size and weight, and be able to actually deliver most of that 5,000mah to your phone.

can someone tell if it also charges devices wirely via the usb c port, as in, does the usb c do input/output charging (not just input to the battery) as some power banks do?

Yes the USB-C is an input/output. You can also charge 2 devices (it’s only 5000mAh though) one wireless, one wired at same time

I emailed Anker as wondered if you could attach it magnetically for convenience, but use it wired to charge faster and got this reply...

You can physically attach the battery using the magnet but charge with the cable attached. In this situation, only the cable charging (via USC-C to lightning cable )works, the wireless charging will stop (the wireless charging and cable charging do not work at the same time for the same phone )

When you’re on a trip taking a bunch of videos and reach 10% by 2pm, you need something to slap on the back to keep going. You don’t have time to plug-in and use two hands to carry battery, wire, and phone.


This will make even more sense when iPhone ditches the plug too. I wouldn’t be surprised if Apple made a thinner version that doesn’t suck when you put it in your pocket while it’s charging
