Great product

Excellent product. Have used it a lot. Will buy again for friends. Legal on airlines. Be careful not to buy one that exceeds airline limits on power.

Second time purchase and second chance, maybe last if time will tell.

Tbh idk why I'm buying another. The first one I bought, broke within a month of buying it and idk how it did. I mostly left it in its box, and it doesn't help how my lazy ass didn't tell the company or write a review about it and now its most likely too late and is pointless to do. I asked friends which to buy and they recommended other brands yet I keep coming back for the less weight and the high capacity. I just got my second portable charger which is this device and so far its heavier than I thought, but i hope it will last longer. What I like so far is that there's 2 lights and a half when I pressed the button, out of the box which is good. I really need this one to last because I'm going on a trip soon which I need it for, and even though there's many other cheap ones that have much more capacity, it either doesn't have high\good reviews, it is very heavy, or both.Just like the saying, with cheap products come cheap quality. I'm kind of sad that I didn't notice that its a USB charger and not a USB-C because I bought cables to go with it but meh, I have other USB cables so I don't mind as much since I'm planing to buy a phone with a USB-C charging port and how everything is slowly switching to USB-C. I know its my fault that I didn't ask for a refund or new one when I could have, and now with my messed up brain think it was a long time ago or at least past the warranty so I doubt I can get a new one, and even though I do ask that if there is someone that reads this, is from Anker I hope something can be worked out or check if the warranty is still available or help me check, since idk how. I wont put too much mind on it since its mostly my fault though adn as I said before just hope this device will last at least a year. Also if you or any readers were wondering I bought a (Anker PowerCore 26800 Portable Charger, 26800mAh External Battery with Dual Input Port and Double-Speed Recharging, 3 USB Ports for iPhone, iPad, Samsung Galaxy, Android and Other Smart Devices) before. I might come back in a year or 6 months or if anything happens to change this or add on to it as I see others do. (Edit) OMG WOW I thought I wouldn't be coming back in a few months but Anker responded to my problem very quickly and got in touch with me. They told me that I could still get a retry/ new compatible charger if it was still in the 18 month warranty. They sent me a email asking for the serial number and shipping address for clarification and said that they would get me a new one and then check in 7 days to see if its up and running still. I'm both really happy and surprised on how Anker helps their customers, even though I know its for more to trust it and to buy more from it. And it worked, at least for me. I'm planning to buy more in the future from them, yet first clarify that I'm buying the right cables and tech since im not so smart in that compartment.
