Customer Ratings & Reviews

I was hunting for a portable charger that I could take to work and on travels (small & large). I grabbed an older model Tzumi but wasn’t really sure. A representative came up to me and answered some questions I had, but also recommended this Anker model, which he said was relatively new to Best Buy’s stock. I decided to switch and picked up the Anker. For reference, I frequent this location so I have pretty solid relationships with a lot of the reps, including this guy. I really like this product! It provides about 4 complete charges for my iPhone 6S+ and it charges to 100% in about an hour (depending where my % was tp begin with). It is also fairly quick to recharge the charger itself.

I purchased this battery to act as a portable charger in place of a 26000mAH battery, to cut the weight down on an 8 day hike. This little beastie was perfect. Fits nicely in a pocket, and weight is very manageable - yet recharges my phone , watch and sat nav multiple times. I've now used it on a transatlantic flight as well on a back country hike , and it's still working great.

This is a great size and is easy to pack but most of all, I am able to get about 3 full charges on my iPhone X. It charges very quickly. Super reliable.

Great power and small size. very reliable. I have purchased 12 of these over the years and I keep 4 at the house always ready to go! Please see my detailed video review here: https://youtu.be/RiHfpFRPWaM

Let me start by saying I absolutely love Anker products. I have 2 wall plugs and wireless charger. So when I initially opted for a Belkin I questioned myself for doing so. And sure enough 3 months later, I went back and purchased the Anker. The Anker has several advantages compared to the Belkin: lighter, smaller, high-capacity charger, and faster charge. So far, the Anker is my preferred charger of choice.

Needed a new power source for extended backpacking trips. This thing is light, simple to use, and gives me at least 4 extra days of iPhone power while on the trail. Much better and lighter than previous units.

I’ve used an Anker for my iPhone 5 & 6S for probably close to 7 years. My previous one is about half the size of this buy not sure of the ma of it. I could get 4 full charges out of it for the first few years and then maybe 3 and it just kept dropping a little bit each year. Then 2 weeks ago I couldn’t get more than a 50% charge out of it. Not bad for a product that I’ve had for 7 years or so. I decided to stay with Anker and went with this size since I like it to fit in my shirt pocket. I should easily get more than 4 charges out of this one for my 6s. It’s a nice size. Not too thick and fits in a shirt pocket. So when I’m walking and have to charge my phone both it and the phone will fit into my shirt pocket. The one thing I was surprised was that it did not come with a USB to lightning cord with it. My last one came with a 3” cord plus the charging cable to charge the unit. So I’ll just keep using the same cord from the old one. So far I think this is a great product and by the length of life of my last one I think Anker makes a great product.

The charging speed of this thing beats my regular fast charger. I use a Samsung Galaxy S7. Love that it is compact and can carry it at work while I'm listening to my podcast. I can charge my samsung tablet with it as well. Mos Def recomend.

Size and power delivery is just what I needed for my minimal traveling requirements. Quick charging times and product reliability for me was fulfilled. Would buy Brand from Best Buy again~!

I often go out for long hikes and I use an app on my phone to record my routes. I also go on overnight/weekend camp outs. There have been times when I have killed the battery on my phone - this charger is just what I needed. It will charge a fully depleted phone at least three times which is more than enough for me. It takes a while to re-charge the unit completely but it charges my phone quickly. I would definitely recommend this unit!

Charges very fast. Excellent construction and no excess heat buildup. Tiny and simple. Would buy again

Holds multiple phone charges and supports fast charging! Fits nicely in a coat pocket.

This charger is relatively light weight and easy to store in a backpack or purse (or a pocket, although it's an inch thick). It holds it's charge when not in use and was able to top up my LG V35 charge and my Fitbit charge a couple of times without getting close to needing its own recharge. It comes in a handy pouch with a short charging cable.

I really like this so far. I got it to carry in my packpack when im hiking because its fairly lightweight at only 4 oz and doesnt take up a bunch of space. Iv been able to charge my fone a few times befor i need to recharge it.

I love this Anker product, it’s very light, compact and portable. An excellent little charger to provide your devices with enough power to last you throughout the day. Plus with the right charging cable, it supports fast charging, how cool it’s that? For its price, it’s perfect.

I have a Note 9 and I can get 2.5 full charges out of this smaller charger. The charging is fast and blue lights let you know how much battery is left in the item itself. Was tossed up between this one and the larger one but I needed something more conpact. This was a great buy

As always, Anker products never disappoint. They are always good quality, great price and it's always worth paying a little more for this brand than it is for the cheaper backup batteries. You get what you pay for! I like how this one is small and has quick charge as well.

This is a great portable charger that can easily fit in a purse and it charges quickly. It was exactly what I was needing and looking for! I would recommend this charger for those who need to have their phone charging while they are at work.

I lost my old Anker battery pack and was so happy with it that I went ahead and bought another one on my way to another trip. This one is also working great so far, it gets recharged in just a couple of hours and lasts for multiple iPhone charges.

This is small and light enough to carry in my coat pocket, and it is powerful enough to do "fast charging" on my samsung phone. It recharges quickly and the light indicators are self explanatory.
