I bought my PowerCore 13000 in October 2019 off of Amazon during a deal. I needed a power-bank because of my campaign trips with my boy scout troop. I would be away from power from 2-3 days ad would not be able to charge my phone, drone, or GoPro. I had a couple but they were pretty low capacity and would not even give my phone one charge. I was looking for one when I remembered that I had bought a charger form Anker and they had power banks too. I found the PowerCore 13000 on Amazon for a deal for $25. Deals for Anker products happen frequently. If you are going to buy one wait a while because one of these might pop up. The PowerCore 13000 works very well on my trip it charged my DJI Mavic mini, iPhone 7plus and my GoPro hero 7 black. I still had enough battery to charge my phone again. The PowerCore 13000 has 2 usb ports so you can charge 2 devices at once. I recommend charging it overnight because its big battery takes a while to reach full capacity. Once it is full charged you won’t have to charge it again for a while. It is also very helpful for around the house if you want to charge your device and walk around or your charging cable is not long enough. It also comes with a little mesh bag to keep the PowerCore 13000 and the charging cable. I definitely recommend this to anyone who is a camper or active person.

The PowerCore 13000 was my first Anker purchase back in 2018ish. I used the crap out of it taking it with me on all my trips that I was taking then, to work, and virtually everywhere I went. I lost the bloomin’ thing on a Southwest flight from Louisville to San Jose CA. I left it in the seat during a plane switch. Broke my heart, but I ended up replacing it with the Powercore 26500, the largest capacity batter sold at the time with three ports and two micro usb charging inputs. Though the larger capacity is VERY USEFUL, the device itself is rather large and not practical to carry in your pants or jacket pockets. I’ve often thought about repurchasing a 13000 for the portability, but at this point it would just seem redundant. Glad you’re happy with your Anker Product and it is the same reason I swear by Anker brands.
Leaning tower of power!
Yeah these are just mine I kept, I gave older ones away as I encountered people with needs.
Look what they did with them.
I think the Powercore love goes way back
Nice review. Mine is going strong after 4 years of use. Its a tough trooper.
