Anker PowerCore+ 26800, Premium Portable Charger, High Capacity 26800mAh External Battery with Qualcomm Quick Charge 2.0, includes PowerPort+ 1 with Quick Charge 3.0 Wall Charger

The unit I received was obviously used. The case had a nick in the anodization suggesting the previous customer had been rough with the unit. The end plate (with the compliance information) had much of the lettering worn off, and there was evidence of significant rub/wear on the end plate finish. Either the previous owner was very rough with the unit, or had used it quite awhile before returning in it. Alternatively the unit might have been remanufactured. Since the unit has "new" on the insert sales invoice I'm concerned.First photo is end plate from a new unit posted by another Amazon customer. Second photo is end plate of my unit. Third photo shows damage to case of my unit (as shipped). Fourth photo is cropped view of damage in shipped unit.

One of the other reviewers said it best that, if you add up the actual cost of the quality Panasonic and other components, it is higher than what Anker sold it at and what Amazon currently sells it at. Yes it is "only Quick Charge 2," but this bank actually charges devices faster than some QC 3 battery packs. Also, it does the very rare thing of allowing a Quick Charge charger to fast charge the batteries. There is only one other battery pack that I recommend that I just purchased, and is QC3 compliant, but has less cells, which is the Aukey AUKEY 30000mAh at this link https://www.amazon.com/gp/product/B01HRAG2KM/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 I have one lightnng, one micro USB and one USB cable, all available on Amazon, links here https://www.amazon.com/gp/product/B00NH138F8/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B019Q0U31A/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B01APALS78/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 User biscuitownz posted the best teardown video I have seen at this link and I have included his great pictures below showing the quality Panasonic NCR18650B MH12210 Lithium Ion cells used [...]

I have been using this charger for nearly a year and it has not let me down. I use it with a Samsung Galaxy S7 Edge, an iPhone 6 Plus, Samsung Gear S2 Qi charger, my GF's personal vaporizers, and more; it is surprising how many charges you can get out of this power bank. I have had it last for full camping trips, and it keeps me happy and entertained on commercial flights, such that I no longer care about insisting on window seats (it keeps up with my S7 + Gear VR while I watch movies on long flights). I even use it on occasion to power my phone while driving, so I can avoid EFI while listening to music through my car's aux port (my Saab lacks Bluetooth so alternator + ignition noise while charging is otherwise inevitable). It is well worth it! I have never had this power bank drain below 20%.I am thinking about buying a second power bank just to keep in the car.On the down side, it is a bit heavy (so have a hefty purse!) and is a bit slow to recharge even on QC 3.0 chargers, but that's all the nature of the beast with just under 100wh capacity.

The PowerCore+ Anker powerbank is amazing. It keeps its charge for months at a time, and can charge multiple devices. It comes with its own cable and charger, charging overnight to full capacity. I use it when I'm carrying a lot of devices or when I'm out with friends, the powerbank supplies more than enough power for all of us. It uses Quickcharge 2.0 (on two ports) and 3.0 technology (on the third port) for fast charging, and combined with its capacity, its the best powerbank I can ask for. This powerbank even comes with a little bag for you to carry it in, although I bought a Khanka case for the thing. Yes, it's shaped like a brick, which means that you should expect to carry a backpack or bag for it. For me, this product fulfills all of my needs.

Update:They have a very strict warrant policy for which they don't budge.I experienced charging issues with my product literally on the day the 18th month warranty expired. Since I was traveling I only got a chance to email them two days later and the point blank refused to honor the warranty.Needless to say I am disappointed but I guess they are within their right to take that stance. They did offer a discount on a future purchase....however I must admit that it left a bad taste in my mouth especially since I recommended them to my friends. I guess I will look around for other options.__________________________________________I am very happy with this purchase.Though I had to think long and hard before shelling out $80 for a charging device, I am glad i did it in the end and I am happy convinced that I have a great product with excellent value for my money.I bought this to take on a trip where I would be on the road every day for a week.This thing allowed me and my family to keep our devices charged so we didn't miss a beat.I had zero issues taking it through the security check and onto the plane in my backpack so I was able to avoid frantically searching for charge stations when at the airport and other public areas.

This thing has come in handy so often. My job often has me in rooms without outlets, using my phone for calls and as a wifi hotspot. I don't know how I'd last a whole day without an Anker. This thing is pretty big. It's not pocket sized at all, but it's still a practical size for a backpack or a purse. And the amount of charge it holds is pretty incredible for the price.I did have an issue with the wall charger failing, but it was within warranty and within just a few days of my replacement request, I had a new charger at my door. Safe to say their customer service is on top of things. I have two Anker batteries and neither has ever failed me.
