There is no doubt that Apple rules the smartphone world thanks to its excellent blend of software and hardware. But surprisingly, the iPhone's battery life is still its weakest point. The iPhone XS has a battery with 2691mAh capacity while the larger iPhone XS Max comes with a 3174mAh battery. The older iPhone X and the cheaper iPhone XR come with a 2716mAh and 2942mAh battery respectively. Since the battery is obviously small on all iPhone models, you need to have a reliable portable charger by your side to get you through the day. So in this article, we have compiled a list of 10 best portable chargers for iPhone X, XS, XS Max and XR. Most power banks support fast charging so you can charge your iPhone within minutes. With that said, let's go through the list.

Anker offers one of the best portable chargers not only for iPhones but also for a host of other devices. The reason I've ranked the Anker PowerCore+ 26800 PD at the top is because it supports USB Power Delivery (USB-PD) technology. All modern iPhones including the iPhone X, XS, XS Max and XR are equipped with the USB-PD technology that enables fast charging from any compatible USB-PD compatible charger. You can charge your iPhone from 0 to 50% in just 30 minutes with this power bank and that's amazing. The power bank goes well over 18W compared to Apple's standard 5W charging speed.

Apart from that, the Anker PowerCore+ 26800 PD has a battery capacity of 26800mAh which should fully charge your iPhone for at least 8 cycles. You can also fast charge your AirPods charging case and Apple Watch at the same time. The best part is that it comes with a separate 30W charger that can quickly charge your iPhone directly from the power supply. Essentially, Anker PowerCore+ 26800 PD is among the best portable power banks for iPhones and it can easily last you more than a week. Just go with this power bank and look no further.
