At some point you’ve probably had your phone die on you when you needed it most (it happens to the best of us). If you want to avoid the dreaded low battery warning, EDCing an external battery pack is a good idea. The problem is most batteries are designed for long trips to last you days at a time, with more juice than you'd ever need along with a ton of extra weight to carry. Luckily, there are some battery packs that check all the boxes for EDC. They're slim, lightweight, and give you just that extra boost in battery to make it to the next outlet. In this guide, we've rounded up some of the best slim batteries for EDC and travel alike.


Mophie Powerstation 2X

Mophie is a name synonymous with external battery packs, and the Powerstation 2X has just the right amount of power at 4,000 mAh to make it perfect for EDC. Despite its relatively large capacity, the 2X won't take up much space in your pockets thanks to its slim 7.7mm aluminum body. For a bit more coin, you can spring for the similarly sized Powerstation Plus Mini as an all-in-one battery and charging cable solution, too.

Xiaomi makes plenty of great “bang for your buck” gadgets and their Power Bank 2 is no exception. The sleek, double-anodized aluminum body not only looks good, but it's also resistant to daily wear and corrosion.

AUKEY 10000 mAh Portable Charger

Aukey knows a thing or two about quality battery packs, offering a wide range of capacities. Although they offer some as high as 30,000 mAh, the smaller and slimmer 10,000 mAh option is great for EDC. Large enough so you don’t get range anxiety for your phone, but slim enough to pocket with ease. You also get a few useful features like adaptive charging through its dual USB outputs and safeguards against overeating and overcharging.

The AmazonBasics Portable Power Bank is simple and affordable but just as effective, with a 16,100 mAh capacity and dual USB ports for charging two devices at once. There’s power overload protection built in and four LED lights to help you gauge how much power is left.

although interesting, i just personally do not want to be bothered to have to not only take care of this, but to take care of the cords i need in order to charge my phone, personally i turn my phone off to keep it's battery in check. then use accordingly when i turn it on
I like the 1byone 10,000 mAh charger with the little display that tells you how much battery % it has left. Has worked great for me so far.
How well does it fit in your pocket? Or do you not keep it on your person?
I just keep it in my backpack. It's about the same dimensions as my Galaxy S7 (with case) just about a third thicker. So it would fit in your pocket if you really wanted.
You can use it to charge your phone while it"s in your pocket, if thats what you're asking. All you'd need to find is a short cable to connect it to your phone. Just have it ride on the back of your phone instead of facing the screen.
Interesting discussion! My work arrangement is that I need to go all day on battery with a Macbook and iPhone. Inevitably, by about 3:00 PM I'm looking at power levels in the 10-15% range and need to get some juice into one, or both, devices. After experimenting with several of the types mentioned here, I settled on the Vinsic 20000 mAh Power Bank (http://www.vinsic.com/). The unit is slim, robust and well made, with a LED display showing percentage charged and two USB Charging Ports. Big advantage for me is that it is thin and neatly fits in the left pocket of a Maxpedition EDC Carry Case. The flat form means that the width of the case hardly changes and so is easier to stow. I have short Anker Powerline charging cables for USB C and Lightning on the other side of the case, plus an Apple MagicMouse. True, the Vinsic is heavy, but my experience is that form factor is a more critical issue for me than carry weight. I tried the Anker PowerCore 20000 and it works fine but could not get the storage right in an EDC Carry Case.
The Mophie powerstation plus mini is one of my favorite battery banks right now. So slim you can connect it to your phone and charge it while its in your pocket. I love being able to move around and have my phone on me and charging at the same time. This does cause some warmth in my pocket when I do this, but I love that I can do it if I want to.
The zendure A2 is a great power bank ive had a load of use out of it its really small, would fit in ur front pocket and a 6700mah battery is impressive for its size and it only takes 3 hours to charge from empty! Or theres a load of other sizes too (A3,A4,A5, etc) 😉
I carry an Anker Powecore mini in my EDC pouch it have daved my day a few times. I also carry a larger powerbank wich can be charged by sun in an emergency in my backpack.
The USB jack on all of the portable chargers (and USB hard drives) I've owned have eventually all come loose. I realize this says something about the wear I put on the devices, but there are some rough and tumble EDC guys out there. I can't be the only one. It would be nice to have something stronger that can keep up with our lives on the road.
I carry a RAVpower 16750mAh and I love it. Two USB ports, 4 LED indicators and built in quick use flashlight. I can charge my phone and my bluetooth at the same time.
I have Anker PowerCore 13000 Portable Charger amongst other Anker products, it has worked fantastically. I can charge wife and my phones multiple times without any worries. Tablet take more of a drain of the battery so can only get about three or four charges on the power brick.
There's a 10,000 mAh version of Flux. I never leave home without it
I swear by any offering by Anker. Morphia, ehhh. I've got a few and I use them all. Nice lineup by the way Mr. Molina.
