Frequently Asked Questions (FAQs)

Did you know it?

What is a power bank and how does it work?

The power bank is a portable charger that allows you to recharge your electronic devices while on the go. It takes charge from a charger, stores it in a battery, and then charges other devices. It is available in a variety of sizes, ranging from slim, pocket-sized devices to larger, lower-, higher-capacity.

Is a power bank worth it?

If you're regularly on the go and can't live without your phone, a power bank is a lifesaver. Simply charge the power bank fully before carrying it wherever you want. When your phone needs to be recharged, simply plug it into the power bank, then continue your activity with peace in mind. That's pretty worth it in anyway, as long as you get the right one.

Can I charge my power bank overnight?

Well, it's a simple answer; yes, you can. With technological advancements, power banks are safe to charge overnight even plugged into a wall or a USB port. Moreover, with the addition of built-in safeguards, you won't have to worry about overcharging or undercharging the power bank.

Should I charge my power bank before first use?

The nice way is to fully charge the power bank before using it for the first time, even if it comes with some charge. It's simple as almost all power banks come with a charging cable that can be plugged into a wall socket or other power sources, such as a laptop's USB port.

It is suitable for all devices because it enables you to choose between USB-C and Micro USB charging. Not only for phones, but also for laptops and tablets. It's super fast thanks to Anker's PowerIQ and VoltageBoost technology, which keeps your phone charged and ready to go whenever you need it.

Promising Review:

Carriers well in my pants front pocket. Not to thick. The length and thickness fit well in a small purse or front pocket of jeans. Use a USB splitter to charge multiple devices. Use a USB C charger for faster charging speed than the mini port.

Our Opinion:

Well, Anker knows how you need a large-capacity power bank battery so badly, that's why this 26800mAh power bank comes here. Yes, with this smart device by your side, you can save your battery life even for days. But don't worry, just because it has a large capacity doesn't mean it's heavy; instead, it's light and compact enough to fit in your bag wherever you go.

Promising Review:

Excellent 26800 mAh worth of power to support up to 9 charges on an iPhone and 2 charges on an iPad. The battery lasted more than four days on a bicycle tour and provided fast charging speeds for my phone. This battery is completely worth it as it can charge 3 devices at once and can be charged by 2 cable inputs for fast charging. The construction is also quite durable with a slim design with a secured USB cable connection so that it will not come out if it is tugged.

This is the best portable charger I've owned to date. It's a little larger than I expected. It's about the same size as my Galaxy S9 and about twice as thick but it has more charging capacity than I ever thought it would. I can charge my phone from completely dead to full 6 times. The the quick charge port with a USB-C cable charges at 3 amp. I appreciate the digital power guage. You know exactly how much power you have left. Amazon also sells a hard shell case that works perfectly with this charger.
