Battery works fine though

I understand the portable battery might get a little warm, but it was very hot while being used, which was a bit concerning.

Good product...revived my dying iPhone battery and could be used multiple times.

Battery life good

The most compact external battery that will give one whole charge at least to your phone

Good little mobile battery backup - so good one of our kids took it and won't confess!!

So far the battery has worked well

Before using this product I had decent battery life under normal use but wanted something for days of high use

Great battery bank

This is a great little battery

Good portable battery.

I bought 2, this is way better than swapping out batteries and works on several other devices

Having a dead battery is a HUGE problem for me

Decent battery life

If you need a reliable battery that can hold up to a commute and a bath (though hopefully not!), get the Jackery Mini

Doesn't hold anywhere near 3350mah, used a 1amp draw dummy load and a usb meter for my test until the battery was depleted, recharged the battery for 5 mins in order to get a reading out of the meter

Jackery Mini 3350mAh Portable Charger - External Battery Pack, Premium Aluminum Power Bank, Portable iPhone Charger for iPhone 7, 6s, Galaxy S7, Galaxy

I really like this battery.

Make sure you are traveling with healthy batteries first

I'd recommend it again, but this time I'm going to replace it with a more powerful battery in a slim design (in pink).

Fast shipping and great little battery pack

This is a great little battery pack.

For my own personal use I prefer the Jackery Giant+ Dual USB External Battery - Portable Battery Charger, Power Bank, and Travel Charger for iPhone, iPad, Galaxy, Android, Other Smartphones and Tablets - 12,000 mAh

I have added a star to my review index based solely on the improvement I have experienced and believe this is a great emergency portable battery backup for the price.

I would reccommend getting this if your a person who uses their phone A lot and drains their battery

The battery, I was more worried about

It does not do this with my Anker 10,000 mAh 2A portable battery or the standard Apple 1A charger

I have added a star to my review index based solely on the improvement I have experienced and believe this is a great emergency portable battery backup for the price.

I thought that since it has a higher mAh rating than my phone battery that it would charge my phone to 100% before itself is exhausted but the 3-4 times I've tried that, my phone only gets up to 65-75%...better than a dead battery but expected better results.

It is not and doesn't claim to be a super durable long lasting portable battery

We all know heat can kill a battery, and this summer has been killer around here.

iPhone 6, oldish, with crappy battery getting crappier

Great little battery, especially for travel when you never know when and where you might have a chance to recharge your phone!

(Product description: Jackery Mini Premium 3350mAh Portable Charger - External Battery Pack, Power Bank, & Portable iPhone Charger for Apple iPhone SE, 6s

A battery saver if I say

Works great for when Pokemon Go drains your phone battery.

I'm returning this and looking elsewhere for a portable battery charger

Great little battery

Like most smart phones, with normal use the battery won't last the day hence the convenience of these portable battery chargers

(I have yet to test this on a full dead battery but will do so asap

And they never have a dead phone battery.

I got this to supplement my lousy iPhone battery and it fits right in your pocket

great battery life for something so cheap.

This wasn't even working off of a completely dead phone battery.

My phone's battery is 3,000 mAh, and from a dead battery I can recharge and still have some leftover in the charger

Great spare battery to take along on anlong trip!

For my application, I'll have to rig up a dummy load or find another portable USB battery

I love my portable battery

Very well made, durable, battery still working great.

We have some issues charging this battery.

Nice looking, hefty battery.

Can recharge my iphone 6S 2.5 times before I need to recharge the portable battery.

Nice design, great battery

Bought this for the wife; her older iPhone doesn't hold it's charge as well as it used to, and she uses this to top off her battery.

Absolutely fantastic battery

i charge it overnight and then i leave my house with it and it will charge my phone for a short period of time before it loses its battery

I ordered this recharger on June 2, 2016, received it June 5, 2016 and exactly 54 days later (and outside of the returns deadline) the battery quit working

Not impressed with this portable battery

Excellent portable battery!

Would recommend this to others interested in a great little battery pack

Great little battery.

My iPhone is an older model and the battery has begun to lose its charge more quickly

I would charge my phone from say 40% to full, and then this battery would be dead.

I thought I had lost this battery, but found that my wife and daughter “borrowed it” from me —-permanently

and I knew I would be taking lots of pictures and video, draining my battery

Very well made, durable, battery still working great.

Amazing useful little battery

One of the better portable batteries I've had

great portable battery

Like many I've been swept up in the Pokemon Go fun and wanted an inexpensive back up battery for my phone for days when I'm not near a charger

This Jackery portable charger gives me confidence that I will not have to worry about finding my device unusable due to a dead battery.

Battery is terrible

Great backup battery.

For me it doesn't hold an entire charge, so that has been disappointing, but it does the trick when I need to make sure I have enough battery in the event of an emergency.

Very nice little device that fits in my purse and lets me go about my day without dreading a dead phone battery!!!

Works as

It seems durable and works as it should.

I tried charging it today and it will not, disappointed as it didn’t even last a year

I'm a bit surprised this item was not working as I am a dedicated Jackery buyer
