Customer Ratings & Reviews

great product, works extremely well, this is what you want in a charger its great! would by it again no dead portable devices here

This battery charger is great. Will charge you phone many times.

Excellent customer service… she patiently answered my questions, she told me how to use my device, she told me tricks as to how to remember which plugs to use. and I love the product.

It is very powerful & charges my mobile more than 3 times from 10% or less to full charge. (Happy with that) But it takes around 10-12hrs to get fully charged. The specification of the item tells it only needs 7-8hrs max.

I fly a lot and my cell phone is constantly running out of power. And some airports done have charging points or not enough and my cellphone dies. So this little gadget here is perfect to keep my phone with power.

It was nice charger but wasn't expected to be that heavy

Great capacity for multiple charging applications.

Solid charger, a bit heavier than some competitors.

Great for charging on the go. Works great and portable

Took it with me on a trip and it worked very well. We were on a train without cell service and our batteries lost power quickly. This worked easily to power them up,

Decent power bank but takes long to charge. Good for a few charges but newer iPhones might be less. We charged 3 phones before it ran out of juice.

My daughter uses it every day to charge her phone as needed. Recharges well and solidly built. Recommend for anyone that wants to make sure they have reliable back up energy available.

Recharge iPhone over and over again. Only downside is this thing is big. Keep in mind, you can’t take this on a flight. You’ll need the 10000 for a flgiht.

I bought this for a business trip and it was great. No issues with TSA either. I highly recommend picking one up if you're in the need for charging on the go.

Even though I decided that I didn't really need an extra charger and decided that I would return it, I will say that the Best Buy store where I do most of my shopping has a great staff, and is always eager to assist me when needed.

I bought 2 of these and both got stolen so I wasn’t so happy

Used this while working in the hospital mopping floors its amazing

Power banks are one of those products where it's really hard to be sure if what you're getting is actually worth the price you pay, which is why I'm glad that companies like Anker exist. There's nothing too complicated about their power banks, but they can generally be trusted to do a very good job selecting good parts and practicing stringent quality control. As a result I've found that Anker power banks tend to outlast those from pretty much any other brand I've tried. While I haven't had much time to spend with the PowerCore III, I haven't found anything to suggest that it'll break the trend. The unit is definitely chunky, but not overly so given how high the capacity is. The casing is a mix of metal and molded plastic, with a slight crosshatch pattern on the top panel that makes it a lot more visually interesting than the usual nondescript black bricks Anker is known for. Charging the bank itself is about as fast as you can expect for a battery this size, and it easily lasted a few days of occasional use charging my Pixel 3XL and my roommate's phone before I needed to top it up again. I even tried using it to top up my laptop at one point. While the output isn't quite fast enough to keep up with the thing while it's turned on, it was a nice fallback to have when I found myself without my charger. And despite what it may say in the description, the USB-C port works as an output just as well as it does an input. Accessories are very basic, with a mesh drawstring carrying bag and a single USB A to C cable that's about three feet long. Getting a C to C cable would have been nice as it does seem that the USB C port is the only one that lets it charge at full PD speeds, but that's an easy oversight to correct on your own. It's certainly not the kind of product that'll set the world on fire. But for a lithium ion battery, I think that "reliable" is more than enough. If you're looking for a battery in this range, I doubt you'll go wrong with this one.

Great backup battery. Powerfully enough to charge an ipad and cell phone at the same time.

This is great value. Size is great. The amount of "juice" this stores for the money is hard to beat. Will take a while to charge up if you don't use a fast charger.
