[Q] Solar Charger

Hi there,
dunno if anyone start thread like this but I wanna ask can someone recommend me a decent solar charger for my sensation. I google it a lot, but I wanna know yours opinions and experience
Thanks a lot

Waste of money mate. Barely get any charge from such a small panel

Of course they have cheaper smaller versions too, but I would recommend this because of the ample capacity of it's battery.

Waist of money, but if you have some small soldering skills, you could do what i have done, one of this :http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200617398704&ssPageName=STRK:MEWNX:IT
And one :http://cgi.ebay.com/5V-700mA-Solar-...ltDomain_0&hash=item3368ecd49f#ht_7577wt_1037
Solder this up, and you got yourself a charger that is nearly as powerful as the mains charger in sunlight, and still being able to charge while its cloudy!

I've got one of these. They are one of the few solar solutions that can actually work. Can only be bettered if you go for a DIY solution as suggested but if you want something neat out of the box this is the way to go!

Be careful with solar chargers on ebay and dealextreme. i ordered two for my old inspire 4g. First, I made it wait for 10-12 hours in sun to charge its internal battery. Then i plugged the charger to the phone. It just charged for 1 min. Then, i thought something went wrong and i looked inner parts of the charger and I was shocked. The battery was a cheap-old-used nokia battery. There is nothing about to be trustworthy. The other charger had some different battery but it was also some cheap-crap. I am going to test the pannels for the output current and voltage. I will combine them to get a good current but i dunno if are they working. I will test them in the lab

I've found that unless you are in super bright sunlight on the middle of the beach when the sun is directly above you that solar panels usually give off less then half of what they are rated for. When you put it through a booster you loose a bit of that too.
I think a better halfway point would be to use the solar to charge up a rechargeable battery then put that through to boost converter. Kinda of like done here: adafruit.com/blog/2010/07/09/how-to-make-a-solar-mintyboost-a-solar-power-charger-for-your-gadgets/
that way you don't risk loosing power every time a cloud flies overhead.

I don't have much money

You won't loose power with my solution as it will still charge when its cloudy
Its cheap too!

My New Best Friend - Anker Power Bank 8400 MAH

Here she is. My new Power Bank. Got it in yesterday. The 2 volt port fully charged daughters iPad out if the box and still charged phone. Will do more testing and post results but it appears to be as advertised. Smaller than I thought and charges fast. Size comparisons attached. Used my old HD2 as comparison since photos were taken with Sensation . Definitely recommended!

Alright. I know I said I was going to review this device, but I don't think that's necessary. I use my phone nonstop. I'm usually having to charge by noon. So at around lunch time I plugged my phone to the powerbank. Connected to WiFi and played pocket legends on and off for about 30 min. Finished that and read news for the rest. Back at work streamed comedy radio, read some pulse feeds, everything syncing, forgot to turn WiFi back off lol, but didn't matter. Got home after work and played FIFA a bit, read some pulse feeds again. Downloaded some stuff and still have all lights on the powerbank. At this rate I won't have to charge all week. Hell I've had it for 2 days and its already impressed me lol. Thing is just too awesome. I'll let you guys know when it finally dies.

isn't it more logical to have an extended battery with you in daily life? their cost is better and they are slimmer than these kind of things

But with this you can charge anything.... And when you buy new phone you can still use this....
And if there is extended battery with 8000+ mah of power it wouldn't be much slimmer ;-)....
I would buy this in a heartbeat if I had the money.... But for now its a dream...

how long does it take to fully charge your phone with it and how long does it take to charge the "unit"? thanks.

Just looked for this on ebay and it's selling for 55 shipped

Question!
When charging on either of the ports, check your battery info.
Does it say it's charging over USB or charging over AC?
If USB, it'll only draw under 500mAh, not the full 600 or 2000, so as to protect PCs' usb power circuits.

Thanks for the info, I had search something like that since long time !

Well that's the beauty of it. It's slim in its own right for what it does. I'm not exactly sure how long it takes to fully charge. It's my habit to plug up my electronics at night so not sure.
I do.t get the pop up that says my phone is using more current while I have it plugged into it and usi.g it so I guess its full ac. The 2v port charges an iPad and the other my phone in the car so its a powerful device. I see it as way more convient than extra batteries cause its interchangeable and I don't have to replace it with new phones and devices. My opinion of course .
The USB cords that came with it have adapters that can be switched with different connector types. Their is a mini and micro USB, one for camcorders, cameras, and something else. I'll take some pictures and post um when I get home. I'm at my brother's place now. Stay tuned.

Portable Chargers

I dont have a nexus 4, and wont for a couple of months, but since it doesnt have a removeable battery, these portable chargers might be useful.
2200MAH
2600MAH (these look really nice)

Have you tried them? I'm wondering what the reliability is like, do they quickly lose the power to hold charge?

I prefer the looks of this one better. Almost 6 full charges, for 3 dollars more than ordering and carrying around 6 of those things.

Ive tried the second one with my Epic 4G Touch. It drops about 1% each day that it isnt being used. It can charge my Epic (1800MAH) once, and the second time, goes about 35%

An important thing to note is that if your phone has a 2100mAh battery and you have a 2100mAh portable charger, you will not get a full charge out of it, as some is lost in transition. You will usually only get between 2/3 to 3/4 of the capacity of the portable charger transferred to your phone.
I have this for my Atrix 4G and will use it for my Nexus 4 when my back order ships. The Atrix 4G has an 1880mAh battery, and I get about two charges out of it. It is about twice as thick as the Atrix, but about half as wide and about an inch shorter. It also functions as a laser pointer and flashlight. It is rugged enough that I bring it camping with me and don't treat it with much care and it still works fine. Very solidly built.

I bought something like this from a seller on ebay, it came from china. It broke right away, but it seems people are having better luck then I did.

I really like the first one in the OP. I like that it can easily be plugged into the phone while using it. I just wish the capacity was a little bigger.

Anyone have experience with or can recommend a unit that is direct plugged and not needing a USB cable? Something more for emergency charging that is pocket portable carried for backup use for uses such as a quick charge at a concert or sporting event. Carried in blue jean pocket are a other small pocket.

I just ordered this for $23. It looks really thin and has a retractable micro usb plug, which is huge for me. This may be good for the person who just posted before me too:

I also ordered this one for my wife:
http://www.amazon.com/Anker®-Astro-...UTF8&qid=1353778415&sr=8-1&keywords=Anker+lip
In addition, the company, Anker, also has a few bigger models with a lot more capacity if you're interested. I haven't bought any of their products before, but the reviews all seem to be very positive.

Battery died....replacement ideas...

I've just joined the dead battery club with my 6800 tab..
won't charge at all.even stock charger no icon nothing....
been on charge all night and have tried numerous things no response.
haven't bricked it went flashing anything just have been busy
Lately haven't used it and must have drained flat.have read before
once they get flat they won't charge as need a small amount of power
From battery to activate charging circuits.
What's the best battery to put into it? Stock one on ebay for 24 usd
Just thought I would ask but is there a bigger capacity one that would fit?
Anybody done this before just looking for ideas..
i will take the battery out and try charging it with a 3.8v mobile
Charger or camera charger by using some wires if any success will
Post up if works...thinking got to put small charge into it then can use wall
Charger.

Well ordered a new battery from eBay 28 bucks delivered...
Just decided to open it up and play with it tonight and got it charging now with the old battery.will let it charge for ages before turn on.new battery still in mail.
Got it working by unplugging the battery for a while and reconnecting to wall charger.note before doing this it would not charge no matter what I used..eg 2 amps etc
Not sure why it works but read it somewhere and worked for me too.

Tab seems to work sometimes and charges ok with old battery then later i turn it on and nothing..
wont wake up even with wall charger plugged in.never had problems with deep sleep before,
maybe a couple of roms ages ago but the one im currently using hasnt done it before and been
using it for ages.im guessing its the battery playing up.anyway got my new one in mail today
and then tab wouldnt start again and i know its not that flat.I decided to change the battery and are
charging now will leave it on charge for ages till full before turning it on.
Do i have to now delete the battery stats?
thanks..

My P6800 is also dead. Won't charge, whatever plug I try
Just ordered a replacement battery + tools for opening the device. Hopefully that will fix things.

I had very similar problems to MRBR7. I was about to order a new battery, but they were over $60 on ebay at the time. I ended up just buying a new tablet - a Nexus 7 2013 - rather than putting money into the old one.
However, I decided to experiment with the GT 7.7, so I took it apart, popped out the battery and hooked it up to a specialized charger than I have to remote control cars/planes/copters. The charger "conditions" LiPo batteries - discharging them and then balanced charging them back up. That worked. After the special charger did its thing I put the battery back in the GT 7.7 and it was happy.
Since then, though, I've had several mysterious and spontaneous reboots. I'm thinking of putting the stock ROM back on it to see if that will stabilize it.
Another weird issue is that the tablet doesn't seem to track how much battery power is left very well. It can drop 10-20% in a few minutes. I know it's not really dropping, but it is certainly weird. Now that the batteries are cheaper on ebay I may order one and replace it.
Edit: Update:
I did put the stock ICS back on my 7.7. It has been behaving nicely since then. No crashes. No reboots. No funny battery behavior. So I think I'll just leave it like that. Putting Nova Launcher on it meets most of my needs for customization, so I'm happy with it.

My tab is dead again. Don't know what happened. I'll try disconnecting the battery from the tab and connect it again, and then try to charge it. It won't charge now what ever charger I try.
If it doesn't work, I might go for the nexus 9

I have a new battery that I am about to put on eBay, but it probably depends on where you are located as to whether it is worth your while. I am in the UK.

I live in Norway, so that's doable. The one I ordered on eBay took around 5 weeks to arrive...
That being said, I don't know if I will invest more in this tablet if it just keeps on destroying batteries. If I get it back up and running again I might try the stock ROM to check for battery drain.

My tab is back from the dead (again). All it needed was a little bit of power-love from the original ac adapter. Still using the replacement battery.
I've flashed it with cm11 and it runs great.

Dear all,

Tried to use the use the prying tool, pry the silver binding from around tablet from glass edge but still cannot open it even the plastic prying tool was broken.:crying:
Is there any tips or guide that can share,please?
Thanks so much

Samsung wireless charging battery case

So for the s7 edge I opted to get the mophie battery case because neither was water resistant and the mophie charged faster and gave more protection. With the Note 7 the mophie one isnt out yet, but the samsung one does have water resistance now. With 3100 mah i think itll be enough to get some good screen on time. It does come halfway charged so i recommend charging it before use. It works as simple as putting it on and turning it on.
I purchased this on amazon with prime shipping because the samsung website is so backed up they couldnt even give me a date when they might send it.
First up is the packaging. Its nothing special just the normal samsung packaging we've grown accustomed to.
Package contents
How it looks installed
Side comparison view
Bottom view (doesnt cover usb type c port)
Overall this will do its job but dont expect very much protection as the front is totally exposed. The charging is very slow. It does make the phone both heavier and thicker as is to be expected and makes 1 handed use harder but its a phablet so who cares. I do reccomend this case, but it is a tad expensive. On the other hand though you have to pay to play. Let me know what ya'll think. Will you get one?
Here is the amazon link https://www.amazon.com/dp/B01ICERRPG/ref=cm_sw_r_cp_apa_.B2VxbV2D5CCX

Sorry for some of the pics looking bad, i think photobucket messed em up. Shots taken on z force

Congrats man... Can you please let us know how does the battery lasts? From what i i know it does say battery is 3100mAh but on the back its also written that usable is a lot less than 3100. Anyhow let us know how much total time you could get without plugging it back in.
Also can you confirm does the backpack charges wirelessly or no.

From what I read this only outputs at 1.0a which is gonna be reaaaally slow compared to the standard 2.0a or fast charge. Does it show any specs on the box anywhere?

The backpack itself does not charge wirelessly, only charges the phone wirelessly.

It is slow, but the way i look at it is, does it need to be super fast if its on your phone like all day?

About 3 hrs to full from 16 percent.. idk if it would even make it to full if you are using it but there you go.

I had this for one day and took it back for the Samsung fast charge power brick. The case made the phone very warm and just slowed the drain of the phones battery while in use.

Yeah at one point I was just cruising Facebook and I kept getting notifications about the device charging too slow. And this was while on wifi with the display at about 50%

Alright, so update. The charger doesnt charge fast we all get that. But it does work well enough that i started today at 500am and it is now 624pm with what i would consider pretty heavy usage. Probably a good 5 hrs screen on time and my phone is at 61 percent with the charger totally depleted, i started the charger at about 80 percent battery. I didnt browse the internet too much i was playing a game called dokkan battles pretty much the whole time with screen at about 25 percent brightness because the room i work in is dark. Just some figures for you guys i will keep updating as info is necessary.
As far as the power bricks go they are nice. And significantly faster, but i like not having to carry them around or plug them in, just one button and im charging.

I think for less than half the price with more capacity and 1.8a output, I would rather have this. It isn't waterproof and no access to spen though.

That could be legit

the samsung backpack charges the phone from 0 to roughly 40% - just tested it with my completely drained note 7 - charging....did not use while charging......turned phone on - battery level was 41% on the phone for about 30 seconds, then dropped to 40%.....
backpack was completely drained at the end of this.
i agree with the OP that it is MUCH easier to have this on the back of the phone rather than lugging around a power bank and cord. however, the backpack battery case is really expensive given the mAH it provides.....
i bought two of them b/c i'm on the phone all day talking to clients from my car.....my two cents is that the cost is worth the convenience, but most others will likely disagree......
cheers.

I'm just curious, if you're in your car, why can't you just get a fast charger for your car and charge it while you're in the car?

Cords.....hate having to plug snd unplug. Also in in and out of my car all day. This way I have one backpack on my phone while the other one is connected to my fast charger in my car....

My Samsung backpack charger took the phone from 20% to full with 1 dot left. I changed wireless charging settings to slow charge only. Used it a few times while charging for light stuff. Gets a little warm while charging. I'm pretty happy with it. No cables and has pass through charging if you need it. Makes it twice as heavy though. I recommend it.
