Good portable charger **Review** - Nexus 7 (2013) Accessories

Hi guys!
Thought id share my find here picked up a momax charger to keep my n7 charged on the go! Love it.
Outputs about 1.5 amps seemingly charges pretty fast. I have charged my N7 from 10% to 100% withing hour and a half.
Kind of new to the whole portable charge thing but I love this little thing. It is small feels of quality and has nice blinking leds to indicate charge level.
it is 4400Mah capacity.
Pictures are attached.
Paid about 25$ not including shipping.
The price has come down I believe I might grab an extra one.

Low on power? What about a solar battery carger ( Mini review )

Hello.
Edit: Read the last line first... not worth the money!
Low on power?
I am currently testing a battery pack with solar panels.
I've taken some pictures and uploaded them to flickr while it's charged my phone.
Click on the pic for more pics.
I did first a charge over night from my phone wall charger (the charger that comes with it has US sockets.
It comes with a 6 plugs for Nokia, Samsung, MOTO, SE, Iphone 3g etc, and the best of all, Mini usb
I do need a micro usb soon... when my new phone arrives. (HTC Desire)
I have no idea how long it will take to charge the device on solar power, but i would guess days... There is not that much sun here yet. I will test that in the next few days.
While it was charging, the phone was downloading music from spotify, wifi on, no 3g on.
I bought the item DX: dealextreme.com/details.dx/sku.30011 it cost $13.63
charging process in numbers:
[17:40] level 33 voltage 3692
[18:01] level 41 voltage 3816
[18:23] level 52 voltage 3890
[19:12] level 61 voltage 3829 <-- Stopped charging!
Now the solar charger stopped top charge my phone...
It was cheep, just don't buy this device if you need extra power...

try turning off your phone and letting it sit. it may still charge your phone to 100% but not when your are drawing a charge.
charge in day light not moonlight like 17-19:00
and turn damn wifi off
Thanks for the review. I go camping often and this was a thought, but not anymore.
i would really like to know if you turn your phone off will it charge it to 100%
Id probably find a bigger solar panel i used one like that in some school project lol
josefcrist's test I think reflects the reality for all solar chargers with internal battery, even those with double the capacity.
Maybe I'm a little bit off topic, but since I got the same more or less experience with a similar product, I'd like to say a few maybe usefull words on the matter.
I got a solar charger with 2500mAh battery. The led light on one side shows that the battery is being charged (when it is green). Well, i put it on my office's window and the green light never went off (at least for 3 days that I checked). This means that sunlight is not enough to charge it fully.
Then, one day I tried to charge my phone with it. I charged the gadget first with my phone charger (using a usb mini chord). Then I tried to charge my phone. It worked for half hour and then the gadget's battery was drained, while the phone's battery increased for 10% only.
Maybe I had many losses because I used the phone's long micro usb chord (the gadget had only a usb mini adaptor).
Then, I said "Ok maybe I have to charge it on DIRECT SUNLIGHT in order to see if it is really effective". Hmmmm. Well! I kinda destroyed the solar charger (I think). When I went to pick it up (I put it in my car's screen on a really sunny day IN GREECE) hardly could I touch it and when it cooled off i saw that the solar panel became curved from heat (and stayed that way) while it was plain previously.
Now I cannot figure out whether it works or not. Maybe I will through away a few more bucks buying another similar (OF COURSE NOT THE SAME), just to be sure that these things DONT REALLY DO WHAT WE ALL IMAGINE (OR HOPE) THEY DO!!!! PERIOD.
Thanks so much for this review, I always wondered about these.
i use Arctic C1 Mobile solar charger (http://www.arctic.ac/en/p/power/batteries/44/arctic-c1-mobile.html), i guess it's just similar, but with only 3 connector adapters and greater battery. always nice to have it on the way.
maybe try using another phone to charge.....
Thanks for info! Will gonna try the Arctic charger
Thanks for the review... Overheating a charger on a car dash... I can't believe it failed

Good Quality and Quick Spare Battery Charger

I have an LG Lucid which isn't half bad. Unless you factor in battery life.
So I'm ready to pull the trigger on a spare battery or two, as well as a wall charger. You know those ones that you plug the battery into itself.
Anyone have recommendations on an inexpensive, decent charger that will charge a 1800-1900mah battery within maybe 6 hours or so?
Thanks!
Oh- looking on amazon if I can, as I have a gift card.
I just did this for my S3.
I can't recommend one for your phone, but once you know what to look for, it's the same basics across all batteries and chargers.
Do you want it to charge slowly ? You say 6 hours, but that seems awfully slow to me. Is that the point - so you can leave it on overnight ? I have a charger that chargers my 2200mAh battery in ~4 hours.
Look for a charger that will charge at 600+mAh. Often it will charge faster if connected to USB. You want to avoid the ones that charge as slowly as 300mAh. I guess they're good if you want to leave something overnight, but they're going to take ~8 hours to charge the battery !
Anyway - no matter if you want it to charge fast or slow, just look at the mAh output and do the math compared to your battery capacity - you can even use a "calculator" that will do the math for you (but it's really easy - "2200 / 600 = 3.6" - so 3.6 hours, but with some wiggle room for lower than 100% efficiency).
I got mine from the brand Anker - they were one of the few that offered a charger that wasn't ridiculously slow. It's 600mAh from an outlet, 1000mAh from USB (meaning it could charge the battery almost twice as fast). It came with two spares and the charger. All the reviews I read didn't say great things about the "universal" chargers, and they all seemed to have lower rates of charging - but maybe I wasn't looking at the right ones.

Experiences with el cheapo battery and chargers

I would just like to share some of my experiences with a cheap 3$ eBay battery (like this one), as well as ultra-cheap 2$ USB chargers.
I bought this battery early January to supplement my GS3's main battery. At first I used it as a backup battery, keeping it in my bag in case my main battery dies. This worked great for a couple of weeks until I could no longer be bothered to swap out the battery every time I needed to charge the other one. So I ended up leaving the eBay battery in full time. At this point I have grown to trust it, seeing as I hadn't had any issues.
Months went by like this, but by the end of March, I was scratching my head as to why my phone wasn't lasting as long as it used to. I guess this change was so gradual that I didn't notice it for long. Now this past week, the battery has had even more trouble holding a charge. It took hours to recharge, and barely lasted with me listening to music, chatting on fb and checking reddit several times a day. It got to a point where one night, it only charged to 90%, and then the next night it charged up to 45%. It also would only charge a few percent at a time when daydream was on.
Now yesterday, by the time I got home ~16:00, the battery died. I plugged it in, but it wouldn't charge - a battery with a warning symbol icon lit up when plugging it in. After a few minutes of fiddling, I managed to get my phone to turn on, but then it almost immediately turned off. A few minutes more, I managed to turn it on and finally charge using the original charger. After an hour, it didn't even reach 20%. This enraged me, causing me to finally hot swap the battery to the original one. Surprisingly, it charged up to 70% in less than 1 hour. Quite a nice change.
Since this morning I've been using it more than normally (large FTP download, streaming youtube), and I still have 60%
I suspect that the low quality anode within the battery corroded very quickly due to the high stresses involved with powering the phone, and charging rapidly. The thing that I often see online, is people being afraid of batteries blowing up or damaging their phones, but this is highly unlikely. The phone has the battery charging circuit built into it, and it will regulate the CV and CC charging cycles itself. It shuts off the phone when the voltage drops too low, and it wouldn't go over 4.2v because the phone wouldn't charge above that. The only damage that a cheap battery can do is to leak or vent inside a phone - hence the need for proper circuitry in the phone.
I also have experiences using absolutely the cheapest batteries in some of my other gadgets. Both of my cameras use the cheapest batteries I could find on eBay - without any problems. Ironically, for my point and shoot, the eBay batteries last longer and display an accurate time estimate. With my DSLR, the 2 batteries that I bought (originally to make a cheap power supply for long timelapses), they work identically, charge identically and fit perfectly. I also bought some protected 18650 batteries for various LED projects I was working on, as well as for my flashlight, but about half of them are now dead - I suspect due to the protection circuit. So yeah, those are my experiences with ultra cheap batteries.
Now, as per the chargers, I mostly use only el cheapo dealextreme or eBay ones. I've had no issues with charging my old iPhone, my SGS3, tablet, and my el cheapo 20$ Huawei phone. However, they don't work well with my Raspberry Pi, iPad and my mom's Android tablet (the touchscreen glitches big time).
So yeah. I don't know what the purpose of this is. Just had to speak out .

EasyAcc® 18000mAh Dual USB Power Bank Portable High Capacity External Battery Review

In the box:
The box is a very simple cardboard box with EasyAcc on it and a product overview on the bottom. Along with the battery, you get two micro USB cables of different lengths and a user manual.
First Impressions:
The battery feels very nice. It has some weight to it and the chrome trim goes well with the matte black. This battery feels very expensive.
Review:
This battery is probably the best accessory I own. The battery does what it's suppose to do and more. I was able to charge my IPod Touch and my Moto G at the same time and still had 4 lights lit up on the battery. With this battery, you can easily charge your phone fully at least 5 times as promised. The battery feels solid in your hand and it's not slippery at all to handle. It's also easy to carry around too. I was able to put the battery in my pants pocket while it charged my phone and the battery didn't feel like it was weighting me down. It was like having regular phone in my pocket. One thing about this battery is it does take a long time to fully charge since it's 18000mAh. It took me about 10-12 hours to charge this battery and I used a rapid wall charger. Make sure you charge this battery during the night while you're sleep, if you'll need it for the next day. The flashlight that's on the battery is bright and a very useful feature to have. The price is very reasonable also. I would recommend this product to anyone looking for a good quality external battery

RAVPower Deluxe 16000mAh External Portable Charger Battery Power Bank

In The Box:
The product comes in a simple, beige box that is wrapped in a sleeve. On the sleeve, there are specifications of the product and contact information. Once you remove the sleeve, you are greeted with RAVPower's slogan "Power To The People" on the top of the box and RAVPower on the both sides of the box. Along with the 16000mAh battery, RAVPower includes a warranty card, and a thank you card. Inside the box, there is two micro USB cables, a USB wall adapter, and a travel pouch.
First Impressions:
The battery is of great quality and the battery has some weight to it. The materials that the battery is made of attract almost zero fingerprints which is great. The flashlight is very bright for how small it is also. I thought the battery percentage indicator light would be difficult to read since all four lights are built into one, but it's actually fairly easy to read. I like how this battery came with a travel pouch. The travel pouch makes it easy for one to transport the battery, the USB cables, and the wall adapter at the same time.
Review:
Another great battery from RAVPower. This battery is great for someone who wants a battery that will charge their devices many times while not having to charge the battery frequently. With this battery fully charged, you could charge a device at least three times. This battery charged my Moto G (1STGen) from 0% to 100% in about 4 hours. One thing that I am not very fond of with this battery is that it takes forever to charge. This battery takes about 9 hours to charge from 0% to 100%. When charging this battery, do not expect it to use it anytime soon. I wish the battery charged faster, but it is 16000mAh so a long charge time is expected with this huge battery. Other than that, this is a great product that everyone should own. I would highly recommend this product.
*Disclaimer*This product was sent to me for review by EasyAcc. My review depicts my unbiased opinion that I stand by 100%.*
