I have about nearly 10 mobile batteries in my house and constantly rotate out 3 or 4 of them whenever I travel for a variety of purposes. If I know I will only be gone a day or two, I will pick smaller batteries that are easier to pack in a small bag. But if I am going to be gone 4 or more days I will pack my larger batteries and on smaller portable one to make sure I have ample power to keep my mobile devices charged before I am able to get to an A/C outlet. This could be you spend long hours in a conference room or in meetings for a full day, or you simply are stuck on a flight for 6+ hours to you just being a passenger in a really long road trip.
These 5 External Batteries which are also known as Power Banks or Portable Batteries, will help make sure your USB chargeable mobile devices stay fully charged for as long as you need them to between access to an A/C Wall outlet.
EC Technology 22400mAh External Battery
The EC Technology 22400mAh External battery provides an amazing amount of power in this battery that is about twice as long and as thick as an iPhone 6. It has 2 USB ports and can charge a Smartphone and a tablet at the same time, doesn’t matter if you use Android or iOS devices it will charge them. It’s power bank can charge a smartphone 10+ times and it has enough battery to charge a full 10″ tablet 2-3 times depending on the battery size of your tablet. All in all, this is one of the best bang for the buck external batteries as it also has an LED flashlight built in for finding cables in the dark. The one disadvantage is it’s size, it is very bulky and too bulky for a purse, pocket or other small pouch and this one is better for longer trips where you pack a full travel back or have a backpack like if you are going on a multiday camping adventure.

Anker 2nd Gen Astro 3 12000mAh Battery
The Anker 2nd Gen Astro 3 is one of my all time favorite external batteries, not only does it have 3 USB ports so that you can charge 2 smart phones and 1 tablet at the same time, but it has IQ ports that are able to charge up to 4A off a single port, so you literally don’t have to worry about 1 port being only for Samsung tablets, another only for iPhone…etc. You can plug any device into any port and it will adjust and provide just the right amount of power to make sure your device charges quickly. The little circle of light showing how much charge is left has more indicators than a typical 4 button light too and a quick shake will wake up the battery and start charging whatever is connected to it or show you how much battery is left.
It does have mid range capacity and is slightly thicker but shorter than the EC Technology power bank, but it makes up for less capacity with being able to charge 3 mobile devices at the same time.

RAVPower Deluxe External Battery Charger
RavPower also makes a fine 14000mAh external battery that also has an LED flashlight built in. This one can charge a Smartphone 7-8 times and offers tablet and phone charging at the same time. It is smaller and thinner than both the previous 2 chargers listed and has slightly more capacity than the Anker Astro 3 though doesn’t have a 3rd USB port.

Anker 2nd Gen Astro Mini
Finally the last device in our roundup is listed because out of all the lipstick external batteries (which is what they are called because they are shaped like a lipstick and only slightly larger) this one has the most capacity at 3200mAh. This one is extremely portable and comes in 4 color choices (Black, Silver, Gold or Pink as pictured above). This is the most portable of just about all the external batteries and really is ideal if you need to slip it in your pocket or a small bag or purse and just carry enough charge to keep your phone alive for up to 7 extra hours of talk time or up to 70 hours of music play time according to the product specs. It will only charge your smartphone and not a tablet but if you are in a pinch and need the ultimate portable smartphone charger then the Anker Astro Mini is the one you want.
