Better now that it recharges, annoying that it can't be used while charging

It's nice that Apple made this mouse rechargeable, much like their new keyboards. Unlike the keyboards, however, this mouse cannot be used while it's charging. Sometimes I feel that Apple's design team really doesn't think things through. Instead of putting the charge port on the front of the mouse (so that you could plug it in and still move it around), they put the charge port directly in the middle on the bottom of the mouse. Basically, this renders the mouse useless while it charges. You only need to charge it once every few weeks/month depending on how much you use it, but still, poor design choice.

Other that that, it's the same great Magic Mouse you know and love. It really is nice having it be rechargeable, instead of going through tons of batteries over it's lifetime, like the previous version.

worked great for a couple of months but started to stop charging unless I was holding it a certain way

Good concept, but charger often stopped charging midway and I would have to disconnect, then reconnect the usb wire to get it to keep charging

The positive is that it works as described.  The unit had all the cables and managed to charge my galaxy note, nook and even my e-cig passthrough without troubles.  It charges from USB pretty fast.

The things I found frustrating are :
1. when it detects any strong light, including indoor lighting, it starts attempting to charge. Even when i would rather it not.
2. when its in decharge mode, it doesnt seem to charge at the same time (even though it showed it was). I had it in real strong sunlight charging my phone and it decharged as quick as when its at night.
3. if it gets real hot (like in the car window), it will show itself charging even after putting back in its sleeve. You have to cool it down to get it to turn off.
4. it said it could recharge in a day, but i found it charges to 3 bars over a day, but takes at least 2 full days to get back to 4 bars.

Update:
Bumping up from 3-star (due to the product) to 4-star (due to product + customer service). Excellent 5-star customer service from Anker! After I returned the product and made this review, they contacted me (I never contacted them) saying they would refund me the full amount (if I hadn't shipped back the return yet) or send me a free unit of the same type for my trouble with the product. Since I genuinely couldn't use this one (the USB plug issue) with my phone/case and was planning on buying the 12000 mAh Astro3 model for travel, I asked if I could get it for free instead. And if not, then I won't mind not getting any compensation and appreciate their gesture. But that was outside their budget, so they gave me a 50% discount on the Astro 3 purchase instead. Anker went out of their way to make sure the customer was satisfied. I would highly recommend Anker products for the customer service and general product quality. I have a 12000 mAh Astro3, a 40W 5-port USB wall charger and a 24 W 2-port car charger for about 1-2 months and I have had no issues with them and extremely happy with those.

Really compact and well functioning charger. Battery holds charge and seems to be close to the capacity they advertise.

Unfortunately, as others have mentioned, the built in micro-USB cable it too thick to fit past most phone/device cases. That kinda puts a dent on the portability factor.

Also, it has no real on/off button. It detects when you plug in the device. But seems to have an issue if the device gets disconnected at the other end of the cable. For example, I used the normal USB port and a magnetic charging cable with my phone. When the magnetic end accidentally disconnects and I reattach it, it doesn't start charging. I had to unplug the cable on the battery pack end and replug it in for it to start charging. Sometimes I even have to unplug and replug the build it cable for the other USB port to start charging.

Lastly, the built in USB cable lock in pretty tightly (as in stretch the cable) into the micro USB charging slot. So I'm worried that in the long run it might break more easily due to the stress on the cable. But this part is just a hypothesis, not that I have had it long enough to break.

I consider Anker to be a better brand than EasyAcc since the 12000mAh EasyAcc battery pack that I got sometime back hardly charges my Nexus 4 2 times. So, it lost the capacity pretty quickly. But for the portable option, I'm forced to go with this EasyAcc product after returning my Anker Astro Slim3 :(

Update from three stars to one star:after continued use it's become frustrating to not have this battery pack charge an iPad at full 2.1A. I need this to work while traveling and it can't even maintain an iPad's charge while in use. I can have it plugged in, spend an hour on a plane, in airplane mode, at medium brightness, and the iPad will still drain 5%. Yes, it would have drained 10% or 15% without the limefuel, but other battery options will actually increase the percentage while in use. I just can't endorse this product when it fails it's own specifications.
-------
I really want to like my Limefuel Blast L130X, but I'm struggling since it's not operating as advertised. It's compact for how much battery life it provides but it doesn't charge at advertised amperage. According to the package it is supposed to provide 2.1A per USB port, but when an iPad or iPad Air are plugged into either port they both will say "not charging" which is what you get when you when charging off .5A standard USB port. It will eventually charge the iPads, if not in use at the same time, but at a slow rate.

You will probably have better luck, but from what I've read, I'm not alone. So consider it a roll-of-the-dice.

I like to say that I wish when I bought this charger, I bought another one that I can plug on the wall outlet when I'm in a hotel in the US.  However, there is the danger of leaving your cellphone still plug-in on the wall when you're in a hurry on checking-out.  I mainly bought this charger, that hopefully will last longer, because when my cellphone run out of charged battery during my car trouble on the road, I have a way of recharging it in the car and calling the tow truck.  Maybe, I should buy another cellphone battery as a back-up.

Works good but needs a slit in the top for charging

It works well, but note that you'll have to ALWAYS leave it plugged in.  Even with a brand new device, the battery will discharge to the point of uselessness if I leave it unplugged or off the charger for a couple days.  In a small apartment kitchen, it's nontrivial to have to permanently give up a power outlet if I want to be able to use this thing on demand.

For the price I expected much more; it has a tendency to spark, doesn't stay plugged into most walls, has to be at the perfect angle to charge properly, and overall it's only benefit is that once you get it to charge your device, it charges it fast. It was fine the first 2 weeks I had it, but after a while it's became a huge annoyance.

Edit: Updated from 1 to 3 stars because although it had issues, the customer service (Anita) was absolutely amazing - they sent me a brand new model with no questions asked. I've waited a few weeks to post this review to see if the issues recurred, but the new model works great.

Can't charge phone and be charged at the same time. Oh wells, it's my backup battery to my backup battery. For $8, it's mostly worth what it is.

I can get up to 4 full charges of my iPhone with this battery, which is great. It doesn't always charge my devices the quickest, but it does it's job in that regard. However, when charging the battery itself in the wall, it will charge for 30 minutes then stop. I have to unplug it for 30 seconds and plug it back in to continue charging. This is very annoying and makes charging the device a long and tedious process. But once it's charged it works great.

What I like about this external battery is that it is just like a clunky case.  Unlike other external batteries that have wires, this one is easy to use on the go.  I bring it along when I know i'll be out for a long time and will likely need some extra power for my battery hungry phone.

While it is the same spec as the internal battery of a sony Z, it never charges my phone completely.  Since it's convenient to use the phone while charging with this external battery, I almost always often do so.  That means that I will only see my battery increase by about 50% at most.  But that is because I'm draining it by using it.  If the I turn the power off and charge it with this, I expect to get about +75%.

My main complaint is that the battery I'm using sometimes turns itself on and off on its own while it's attached to my phone.  It makes it very difficult for me if I connect it while my phone is about to die.  Sometimes it also starts charging when I don't want it to.  This happens usually when I put it in my pocket.  I end up leaving it on the table or in my bag if I want to it to charge continuously.  I'm putting three stars because I'm assuming mine is a bit buggy.  If they all suffer that same bug, I'd give it 1 star.

I'm giving it the benefit of the doubt because it has saved me from a dead phone many times and has allowed me to get more out of my phone.

I bought this for a friend, and initially it would stop charging the phone when the phone was charged, but that feature appears not to be working anymore.  Even without that feature, and it was a good one, I'd still buy it as it does charge the phone well.

I'd wanted to be able to leave the phone on charge all night, and that feature when it worked allowed me to do so.

This was supposed to be a "all in one" gadget, allowing you to charge and sync your bb8900, thus to recharge a spare battery which is a great thing. Except there is one thing that cooled me down the minute I unpacked this - you can't just put the phone in the cradle to charge it! No, that would be SIMPLE. You also need to plug in into mini-USB !!!!! For God's sake, one of good things about charging cradles is you DON'T have to use mini-USB port (which is very sensitive, btw, and primarily not designed for everyday plugging in/out like normal chargers).

Anyhow, this is a really nice 3-in-1 gadget, but this lack of usability is making me give it 1*.

It's nice, holds a lot of charge and charges very quickly. It is heavy though and can take a while to charge. I would buy again though.

Update:

Changing this from a 5 to a 3. I bought this 5/29/15. I used it heavily but intermittently (really based on when I was traveling). I can fully say now that the 2.4V port does not do anything anymore. The 2.1V requires wiggling depending on what USB cable I use. I try the 2.4V with two different cables. Very sad I can't use that one anymore but I can still charge the device and use the 2.1V which I guess is OK. I still like that it's a large bank and I can literally throw this in my purse and feel at ease for several days.

Ehhhhh. It just stops charging, which is annoying. It's not super easy to control. But for the price, I suppose it's what you would expect.
