🔋
Does the Anker PowerCore Slim 10K PD work with USB-C to Lightning cables for iPhones?
Yep, the Anker PowerCore Slim 10K PD works with [USB-C to Lightning cables](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DUSB-C%2Bto%2BLightning%2Bcables%26tag%3Dssw.ans.tx-1-20) for iPhones. The manufacturer mentions it has a USB-C port supporting 20W Power Delivery, which means you can fast charge your iPhone when you use it with a USB-C to Lightning cable. You'll need to grab your own cable, though, since the power bank doesn't come with any. From what we've found, this power bank is pretty flexible and works well with [iPhones](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DiPhones%26tag%3Dssw.ans.tx-1-20), like [models 14](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DiPhone%2B14%26tag%3Dssw.ans.tx-1-20), [13](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DiPhone%2B13%26tag%3Dssw.ans.tx-1-20), and [12](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DiPhone%2B12%26tag%3Dssw.ans.tx-1-20). Just a heads up, make sure you've got a good quality cable, as some reported issues come from snug cable fits, especially with older devices. It's also essential to check that your cable is up to the task before heading out, to make sure everything runs smoothly. If you’ve got the right setup, the 20W Power Delivery can really help speed things up, which is super handy for busy days or when you're traveling. In short, the Anker PowerCore Slim 10K PD is a handy little gadget to keep your electronics charged; just keep that cable situation sorted, and you should be golden!

How long does it take to fully charge the Anker PowerCore Slim 10K PD?
If you're using a wall charger that supports Power Delivery (PD), charging the Anker PowerCore Slim 10K PD typically takes about 4.5 hours. Just keep in mind that the charging time can vary based on the charger's specs. Using a standard USB charger might extend the charging time compared to a PD-compatible one. By the way, this power bank doesn't come with built-in cables, which allows you to use your own cables depending on the devices you have. But don't worry—Anker does include a USB-A to USB-C cable and a USB-C to USB-C cable in the package. If you're using an iPhone, though, you'll need to snag a [USB-C to Lightning cable](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DUSB-C%2Bto%2BLightning%2Bcable%26tag%3Dssw.ans.tx-1-20) separately to fully utilize the rapid charging abilities of this power bank. From what we found in our research, it's pretty normal for portable chargers not to have built-in cables since it keeps them quite flexible. You can use it with different gadgets without any hassle, as you're just swapping out to the cables your devices need. Plus, skipping the built-in cables makes the charger more compact, which is super handy for traveling or just carrying around each day. So, as long as you've got the right cables and a PD-compatible charger, you should have the Anker PowerCore Slim 10K PD fully charged and ready to juice up your gadgets in about 4.5 hours.
🔋
How many times can the Anker PowerCore Slim 10K PD charge an iPhone?
Hey! So if you're wondering how many times the Anker PowerCore Slim 10K PD can charge an iPhone, our research shows it's pretty handy. With a capacity of 10,000mAh, it can generally juice up an iPhone about 2 to 3 times on a single charge. Now, that can vary a bit depending on which iPhone model you're using and how much battery your phone has left when you start charging. For example, an [iPhone 12](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DiPhone%2B12%26tag%3Dssw.ans.tx-1-20) has around a 2,815mAh battery, so you're looking at roughly 2.5 charges from the power bank. On the other hand, an [iPhone 14](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DiPhone%2B14%26tag%3Dssw.ans.tx-1-20), with a slightly larger battery, might get about 2 full charges. These are just estimates though, and factors like your phone's settings and battery condition can shift things a bit. A cool feature to note is that it can do "pass-through charging." This means you can charge your iPhone while the power bank itself is plugged in and charging. It's got a 20W Power Delivery USB-C port, which makes it pretty good for quickly charging newer iPhones and other devices like [Samsung's S10](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DSamsung%27s%2BS10%26tag%3Dssw.ans.tx-1-20) or the [Google Pixel 4](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DGoogle%2BPixel%2B4%26tag%3Dssw.ans.tx-1-20). However, our research does mention a few isolated cases where folks have reported some issues with the ports not always working perfectly, which could affect the pass-through charging feature over time. So, if you plan to use it a lot while traveling or during power outages, just keep an eye on how it's performing. Overall, if pass-through charging is something you see yourself using, it might be worth dealing with those occasional glitches since it still does a solid job of keeping your iPhone charged up throughout the day.
