Nice compact size for when you are traveling overseas and you don't want a lot of extra weight

Quality of build, capacity, ease of use, compact size are all top notch

The size and weight are also wonderful.

Although it was a great size, the ligtening plug did not fit in either my lifeproof case or my husband's otterbox, so we returned it.

The size is very convenient and the 2-3 charges at a time turns out to me more than enough for a solo person even with pretty high device usage

And the size is just right

Good size, charges quickly and works for both Ios and Android phones

Speaking of which, it is the perfect size to hold in your hand with the iPhone, and if that sounds like too much work for you, you can always connect a cord from the device to your phone, giving you freedom of movement

My few complaints would be that the cables are not longer, however this does help keep its size very compact; also don't like having to press the power button in order to make it start charging my phone; the blue LED lights signifying that it is on do get a little annoying

Great size and quick power up!

size is nice too

I love the small travel size that lets you put in your pocket or your backpack

Size is perfect.

It’s the perfect size as too not get lost easily yet not overly large!

Love the size

Very convenient no extra cables needed as they are attached, they charge quickly and are a very portable size

Great size for a purse

Great size - isn’t too bulky

Works great, small size, good price.

Very nice small compact size external phone battery.

Only using the Lightning cable but doesn't hurt to have the other one too; and that mean not to worry about carrying a cable around- built-in flashlight which comes handy at night, or while traveling- decent battery size which at least can bring a phone back to life with a good charge- compact size that make it easy to carry, or throw quickly in a luggage/bag if in a rushWhat could be better: a bigger battery but in the same package/ size, maybe a built in cable so it can charge without the need to have/find another cable

high quality cables feel sturdy, slightly larger size compared to similar amp-hour Anker battery but overall happy in that it includes cables and a usable LED light.

Great portable charger - low profile, but packs a good size charge - able to easily charge two iPhones while away without trouble, and it charges reasonably quickly (about 4 hours)

best i've seen so far for compact size and light weight.

Perfect size

Perfect size no need to carry around cables

Perfectly sized and self contained, and appears to hold charges very well.

I really like the compact size and built-in cables

It is a good size

Great size and no need to carry any other cords

It charged as advertised (very quickly) and the size of the charger was perfect for everyday travel

Lots of flexibility, all in a compact size.

Nice easy size to fit in purse.

Great size - isn’t too bulky

The compact size of the Bolt is also a nice feature.

This size is great for travel, and this is the second one I purchased since my wife wanted one for herself.

It's the perfect size both in terms of physical size and charging capacity.

I found the size to be very reasonable

I've had it for a little over a month and took it with me on road trips and for day long excursions -- it's the perfect size and charges quickly

This battery has some great features – the built-in lightning and microUSB cables are a good design, the size is perfect for carrying in a small bag, and the built-in flashlight is a very nice touch

Nice size and packs the power helps too!

Needed something that can fit in pocket, has decent size battery and built in cables

Seems like it is quality materials and a great size

It is the perfect size -- not too heavy to carry in your purse -- and so easy to use since you don't have to take along a cable.

Nice compact external battery charger with plenty of power in a comfortable size

Ideal size, and

The size is a good too

I liked the size, but honestly I never got to use it before returning it.

awesome size and functionality.

Nice size and weight but can charge my iPhone 6 2-3 times

, it's a small size, and I like how I can tell how much charge is left by the lights

A perfect size to slip into a bag

Good size and not to heavy

The size and shape just "feel right" to me because I can drop it in any pocket and it doesn't seem any bulkier than my chargers with half the capacity of the Bolt

I didn't notice the flashlight feature and would have preferred a more compact size than the added feature I think

The size is perfect to put it in my bag and can charge about 3 times

Really disappointed that this lasted for less than 3 months as I loved the size and the built in cords

This is the perfect portable size, but the design of the included, attached wires is extremely inconvenient

I am concerned with the safety of the device, thought I adore its size and features.

The second was stolen by my wife for its ease of use and small compact size

Great size, holds good charge, and having both Android and Apple plugs attached makes it very convenient, and perfect for helping friends.

It's a convenient size, easy-to-use and very effective

Good size to slip into a purse.

This is the perfect size for my purse.

The size is perfect for day to day use or car trips, and it has lots of power

Perfect size for people who don't want to walk around with a brick sized battery pack

And all in a small enough size to easily fit in a pocket or purse

I love the integrated cables and the size.

I love the size and that it's so easy to carry

quick charge and good size to carry with you

It is a really nice compact size and easy to take with you anywhere

Nice size, and charges relatively quickly.

Also a really convenient size and not too heavy.

Love the size, portability, and attached charging cords.
