EDC, as in every day carry. A must have for the heavy user. Keep in mind that I plug in when I notice less than 50% in the phone battery. No less than 25% on occasion. I get solid 5/6 charges to 100% in 1 to 3 days of use. I try to remember to charge along charging the phone. My regular charge locations have power for each to plug in set up. It has been a good set up for me. Lots of "peace of mind" that you just won't run out of power in 2 to 7 days based on desired use until you will need a recharge at a power point. I also enjoy a 1 foot cable, just long enough for options without coiling cable bulk. I also have a 26500 that we as a family use wherever it is needed, super convenient. Also good for Fire, Earthquake, Disaster or Emergency situation. That one charges 10 to 15 times easy, I usually recharge it once a week with the handy 4 light led charge indicators. Thank you for the read hope it help in your choice. All the Anker products I've purchased have been of highest quality. I don't represent them only myself, Chris Girard (TheBaldCarGuy)
