Still curious about the Anker 733 Power Bank? Here are some answers you might find interesting:

🔋
Can the Anker GaNPrime Power Bank charge multiple devices simultaneously?
Yep, the Anker GaNPrime Power Bank can charge multiple devices at the same time. It's got this cool 2-in-1 design, acting as both a 65W wall charger and a 10,000mAh portable battery. So, whether you're at home or out and about, it's pretty handy. When it's plugged into the wall, you can tap into 65W of power, which is enough to juice up bigger gadgets like laptops pretty quickly. Once you unplug and switch to using it just as a power bank, the output power tops out at 30W. This is because it needs to balance its battery life with supporting different gadgets. Based on our research, while this device shines as a wall charger and can charge multiple items at a time, some folks found it doesn't perform as impressively as a standalone power bank. The efficiency can dip, especially when it comes to meeting its full 10,000mAh capacity claim, depending on what devices and cables you're using. The power bank has two USB-C ports and one USB-A port, letting you charge up to three devices simultaneously. But, if you really want the best performance while on the go, sticking to charging one high-capacity device or splitting between a few lighter ones seems to give better results. So, it's worth considering the power needs of your devices and the quality of your cables to make the most out of your Anker GaNPrime.
🔋
What is the battery capacity of the Anker GaNPrime Power Bank?
The Anker GaNPrime Power Bank has a pretty solid battery capacity of 10,000mAh. This means it can give your smartphone a good few charges when you're out and about without wall power. The manufacturer mentions that besides being a power bank, it can also double up as a wall charger, giving you more flexibility with how you use it. From our research, it's clear that this power bank plays nice with a bunch of gadgets, including the latest [iPhone 15](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Diphone%2B15%26tag%3Dssw.ans.tx-1-20) models—like the [15 Plus](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3D15%2BPlus%26tag%3Dssw.ans.tx-1-20), [15 Pro](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3D15%2BPro%26tag%3Dssw.ans.tx-1-20), and [15 Pro Max](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3D15%2BPro%2BMax%26tag%3Dssw.ans.tx-1-20). People seem pretty happy with how it works with their Apple devices, which just adds to its reputation for being quite versatile. When you plug it into a wall, it can pump out up to 65W from one of its USB-C ports. That's great for quickly charging things like some laptops or power-hungry tablets. If you're just using it as a power bank without plugging it in, it cranks out a 30W output, which is still pretty decent for most tablets or phones. While folks generally dig its performance with single devices, there's a bit of a catch when you're trying to charge multiple gizmos at once. Some have noticed that the power splits between devices, which can slow things down if they're all demanding lots of juice. Overall, the Anker GaNPrime's 10,000mAh capacity and its ability to work both as a wall charger and a power bank make it a versatile pick. Whether you're traveling often or just need something reliable for daily use, it's a pretty handy choice.

How fast can the Anker GaNPrime Power Bank charge devices?
If you're wondering how quickly the Anker GaNPrime Power Bank can charge devices, here's the scoop. This power bank comes with a 10,000mAh battery and has a neat dual-function design. It's equipped with two USB-C ports and a USB-A port, so it's pretty handy for charging multiple devices. The cool thing about the GaNPrime is that when it's plugged into an outlet, it works as a 65W wall charger, which means you get a nice fast charge. But, when you're out and about using it as a portable power bank, the output drops to 30W. So, it's great for charging up to three devices at once, especially if you've got a bunch of gadgets. Our research shows that the 65W fast charging is only available when it's plugged in. The manufacturer set it up this way to balance fast charging with portability, so just keep in mind the different power outputs. Some folks have mentioned that it might deliver less power if you're charging more than one device at a time, and there's feedback that the battery capacity might not feel like a full 10,000mAh. Despite those quirks, people seem to like the GaNPrime for its portability and solid build. It's often praised for being convenient, especially when traveling. So if you're frequently on the move and need a compact charger, this could be a good option if you're okay with the hybrid charging features. But, if you're looking for constant high power for your devices, especially while traveling, you might want to check out other options. Think about power banks with larger capacities or even separate wall chargers. Still, if you want a travel-friendly, all-in-one charging solution, the Anker GaNPrime Power Bank could be worth considering.
