[Q] External Batery

Anyone use the external battery from proporta (turbo charger 5000)?
What it's your opinion, it's worth it?
How many REAL charges can be performed for DHD, and how long it last?
here it's the link

Thank you!

Don't know about that one, but this one is 40% cheaper:
http://www.amazon.co.uk/New-Trent-Dual-port-IMP50D-Blackberry/dp/B004AM1OK4/ref=pd_cp_ce_1
I bought it a month ago, same storage capacity as the one you're looking at, comes with USB cable and 2 adaptors (mini & micro usb) which is just enough to charge the pack and your phone respectively. Or a phone with a mini usb port...
I haven't done any serious benchmarking, but I'd estimate about 3 "full" charges. The pack itself does take some time to charge up, since it's filling up 500mah and I do it via the PC usb port, so a direct wall charge would probably be faster.
I use it as a top up, so normally I plug it the phone in for an hour or so, take it to 80% charge. Haven't done any 0-100 trials
There are a couple more vendors on Amazon, check them out. I have noticed that the price of this model varies over time: I bought it at 22.95GBP, then saw it at 29.95, and now it's 25...

thank you for your reply, do you think the charger of DHD will charge it faster?

I am using the Gum Pro from justmobile and I'm really satisfied. 4400mAh capacity, 1000mA output... charging way faster than standard charger. Lasts for 3-4 charges...

Fantastic, I want that for my DHD

I would think so. I'm not sure about the output the battery pack receives from my USB port (I have 2 ports on the laptop, and one is connected to a hub with 10 outputs of which 5 are normally in use, which is where the pack is recharged from) - but the wall chargers are normally faster in my experience.

Anyway, a slower charge is always recommended, as it's said that the battery performs better with slow chargers, and I can tell you it's truth, I now onlye charge the phone via USB and seems to have a better battery life(not much better, but still, bit better)

well, I have buy the one I posted and I charged with htc wall charger (it will charge my phone 3 times), that's good but today when I try to charge it again it's say that it's empty. I plug it in charger and in 5 min it's full. (it's take around 2 hour to full charge). when I plug my phone back on - to charge it - it's working normal.... it's that ok or it's going to final/death
I mean it needs a inpulse to go back to normal
It's this happend for you guys?

It sounds like it isn't working properly, though I'm sure you noticed .
Proporta offer a no-hassle returns policy, though you will probably have to pay the postage - so you could request a replacement, or just get you money back & get yourself another brand.

We offer a super high capacity USB battery @ 9600mAh for roughly 39 Euro / USD 55 shipped to any country. The down side is having a single USB port output only comparing to Proporta's dual output.

Wow... that looks physically identical (but in white) to the New Trent 5000mah casing. Even the charge/discharge indicators and button.
http://www.amazon.co.uk/New-Trent-Dual-port-IMP50D-Blackberry/dp/B004AM1OK4/ref=pd_cp_ce_1
Er... can you fit double the capacity into the same volume? What are its dimensions?

sorry for bad pic but here you can have an ideea about the size.

got another clone of the new trent one, tecknet iEP380 5000mAh, about £23 via amazon
note these all charge via the mini usb conector , not the micro charger one that the desire HD uses,
its about the size of the phone again, so not an everyday item to carry around, but when your away from a power source for a day or two it does the job well.

my battery life solution

Well my battery life is pretty good, I have the 2750mah and I'm running lightning rom 1.5 with the stock kernel and I get a solid 2 days, but just in case I ever decide to go back to the stock battery I made this nifty little thing. It's an altoids case with a portable charger and adapters inside, and the parts list is as follows:
1x 1N4742A 12V Zener Diode $1.59
Model: 1N4742 | Catalog #: 276-563
1x 6V 50mAh Solar Cell Encap $14.99
Model: 277-1205 | Catalog #: 277-1205
Both of which are available at radioshack, I also had to cut up an old mini-usb cable for the input.
Let me know what you guys think!

Lol that is awesome. How long for a full charge?

I haven't tested how long the solar panel will take to charge the battery in the case, but the battery is only 1000mah, so I get another 30% in about an hour, hour and a half ish
Sent from my ADR6400L using XDA App

quite clever indeed what would happen if you used a couple solar panels in parallel?

I was thinking about it, at 14.99 a piece I just might. They produce 50ma each, so a second in parallel would be 100ma and charge twice as fast.

Wow that's badass. You should consider marketing it
I've often wondered why no one has made a phone case with photoelectric cells that continuously charge your phone.
Sent from my ADR6400L using XDA App

there are not alot of times when i am not near electricity but i agree for those times when i am this is a sweet idea... camping over the weekend comes to mind.

i wish i had the money/time/resources to bring this to market, it is perfect for camping lol, my fiancee and i spend a week in the catskills every summer and im definitely bringing this along this year

Very nice . there is a solar charger in the market but who know how much time the charge.

I went a slightly different route. My Altoids charger will charge any USB device from a readily available 9v battery and one battery will get you several charges.

It has a standard USB port on the end and the red LED indicates when the charger is turned on. A simple switch on the side turns it on and off and it's regulated to 5v like any USB port.
And then my wife completely forgot that I built it and bought me one of these for x-mas.
It's called a Powerstick and has a small lithium battery inside that charges from any USB port, and comes with a bunch of small adapters to fit many different USB devices. The Powerstick cost about $25 + shipping, but the Altoids charger cost me about $15 to build, including having to replace the voltage regulator once after accidentally smoking the first one during assembly. The Powerstick is slimmer, but the Altoids charger wins for geek factor. Also, the powerstick needs charged off USB, whereas I can walk into almost any gas station or Wal-Mart and buy a 9v battery. So the Altoids charger wins on long trips.

Dude make me one n I'll buy it from u

thats sick, i like how the battery is replaceable, you could even use a rechargeable 9v and a solar panel to recharge it XD
mine has a standard usb as well, i just didnt show the proper angle lol, its in the pic below. the portable charger inside mine is an energizer xpal1000

I am FAR too stupid for this crazy ass thing. lol

Dude you need to make a Youtube video on how to make this! You can even charge your phone while is in your pocket!!! (i don't know how safe that is but sounds super awesome!)

It really depends on how much sunlight you have. Volts X watts determines the time it takes to charge. I am building mine tonight, and my calculations indicate about 8 hours for a full charge in bright sunlight.

Anker Slimtalk

Checkout this Anker Slimtalk on Amazon..
http://www.amazon.com/gp/product/B0054V7GOI
Supplies auxiliary power to devices like cellphones. Specs on the Amazon ad state it is compatible with the HTC Sensation. I ordered one and saved $9 using the coupon code: ANKERSWT, which is good until 08/31. My final cost $22.66

I bought this product, but I personally wouldn't really recommend it.
The good:
- Easy convenient to recharge phone
- Include MicroUSB within the unit itself - no extra wires need to be carried
- Included flashlight
- Slim, sleek design
The bad:
- Battery charge remaining hard to see in the sun
- Requires a long time to recharge back to full
- Is supposed to have a 3200 mAH battery life, aka 2 recharges, but barely gives me 1.25 charges on a OEM battery
However it is really cheap at $21.

Expecting two recharges from a 3200 mAH source is completely unrealistic due to fact that energy transfer across such media is never efficient.

anker slimtalk
I got my anker slimtalk yesterday, it looks good, supper slim, easier to take than having an extra battery and having to open up the phone and replace it. And it charge fast as well.

I've been using this for about a month now. I can say that the plug is off and on, meaning it doesn't seat too well and can be charged in a certain position, users may vary. But when it works, it's a handy thing to have just in case you need an extra boost.

I got something very similar in design and size from a local super market (Asda).
It has a 5000mah battery and 2x USB ports on.
Was £8.
It's now gone up to £15:

did you try doing a double charge using the built in micro cord + an external usb cord? this is good for sharing a power source otg.

just a lol info on the anker slimtalk. I did about 3 charging cycles and then put it to the test. I drained my mugen 2600 mah on my hd2 to 3% and connected the slimtalk. I was able to charge to 75% before the slimtalks juice ran out. I'm no math expert but all I got was 72% of 3200 mah. still the slimtalk satisfies my needs for emergency power.

I wasn't really expecting the slimtalk to keep my device at capacity. Just to have enough juice ICE.
I do love it for being thin enough and light enough to fit in my back pocket on the go. I have enough crap to lug around when going out, especially with a 3 year old.

yeah im in the same boat as you. i keep in in my tablet bag when i go to work. i have a lil correction on my post though. i said 72% of 3200mah when i meant 72% of 2600mah. (mugen battery = 2600, on a 3% charge it went to 75%) that would make the slimtalk roughly a 2000mah power bank and not a 3200mah. thats unless it takes roughly 1200mah just to transfer the juice over.

The problem you've highlighted there is present in all these devices.
The battery that is rated at 3200mah is running at 3.7v. The device then has to up that voltage to 5v to input into the phone to then charge the phones 3.7v battery.
With my 5000mah charger I can get just over a couple of charges out of it. Very handy when away from a power source for a couple of days etc.

Why don't you guys just buy an extra battery with an external charger. Wouldn't it be easier than carrying that around?

you have a point but a way to answer that is to say... what if you need to charge anything else that takes a usb cord. (bluetooth headset, ipod, zune, tablet, a friends phone.) i like nerdy things like this charger bank.
dont try this at home! slimtalk+usb hub+hd2+i9000+t989 lol. mind you that your only going to get a 15-20% charge on each

Holy crap! Pick a device! LOL

Can anyone help me with a site which will deliver it to India?

not bad, might check it out

For some reason, the charge dissipates quickly even when not in use. It seems that it loses 25% of battery life every day or two.
I fully charged it, then plugged my phone in a few days later in an emergency. It clicked at 50%.
As of now, I wouldn't recommend this device. I'd say, buy an extra battery instead. Anker batteries are good but this is crap.

That's weird because I don't charge my slimcharger every day. It's been sitting on my dresser for over a week and everytime I get dressed in my closet (walk in) I press the button to see if it did dissipate at all and mine still shows full even after a weeks time.

[REVIEW] Ambrane P-1000 10400mAh Portable Power bank

This is the review thread of the Ambrane P-1000 Portable Power Bank, not to be confused with the P-1040(same capacity but different design that's all)
I had purchased this from Flipkart.com for around Rs 1400/-($23), which is I guess reasonable price for a power bank of such high capacity, the P-1040 model costs Rs300 extra but the only major difference is the design which is more sleeker but other than that everything else is almost the same

Technical Specifications:
High Power Ultra Bright LED Torch
Digital Display
10400 mAh Capacity
Samsung SDI Lithium-ion Cells
Charging Time: 600 mAh Per Hour
Input: 5V/1A
Output: 5V 1A and 5V 2.1A
To test the backup and charge of this power bank I had charged it till 100%(see attachments), and depleted the battery in my Nexus 4 completely, I then charged my phone using the Power bank in the 2.1A port till 100%.
The power bank registered a charge drop from 100% to just 92% while the 2100mAh battery in my Nexus4 was completely charged. Which means this would charge my Nexus 4 at least 4-5 times!
Value for money is there in this product and the dual outputs are great for even charging 2 devices at the same time, many would rather opt for the Xiaomi Mi Power Bank, but comparatively its almost the same and this has a few extra goodies.
I hope this review was helpful, for international buyers you may find this product on eBay or Amazon, and for Indian buyers its readily available on Flipkart, Snapdeal, Amazon.in and eBay.in

Tough Luck bro

Got it from PAYTM with 50% discount @appx 700 and I think value for money. Working great but the build quality could have been better. Overall a good buy.

I know right! Indian brands aren't so bad after all

MobilePal Gen-2 10000mAh Universal Power Bank [Review]

Like the previous product MobilePal Gen-2 Wireless Charging Pad in m last review, I didn't pay for this unit; I got this as a review unit and I'm going to put my honest opinion here. Please consider this if you're looking for a power bank.
I do have several other power banks and to start this review, this one isn't very different. We are reviewing MobilePal 10000mAh Universal Power Bank. I'm sure you must have noticed the product listing on Amazon says "MobilePall" instead of "MobilePal" but I'm pretty sure it's the latter.
Anyway, we'll just split this up in following 4 categories:-
- Boxing & Contents
- Build Quality & Design
- Functionality & Performance
- Pros & Cons
Boxing & Content

"lightbox_toggle_sidebar": "Toggle sidebar"
}
Like any typical power banks, the box comes with the following items inside:-
- MobilePal 10,000 mAh Power Bank
- 1 x 2-in-1 Charging Cable (Micro USB & MFi Certified Apple Lightning Port)
- User Guide
Now, the charging cable do support iPhones and other Micro USB Phones, so you wouldn't really have to separately buy or carry around a long cable. MobilePal has found a very nice way to fit both the ports in a tiny USB Cable.
Build Quality & Design
As a 10,000 mAh powerbank, it's definitely smaller and lighter than any other powerbanks out there with equivalent capacity. The body is made of solid plastic with matte surface. Overall, the finishing looks great unlike some cheap products out there. The powerbank doesn't have any LED to show the charge status, instead they have integrated a small LCD display which is very cool. It shows the battery capacity in percentage and it also displays, which output the charging unit is connected to.
It has 2 USB Outputs and 1 micro-USB input. It also has an LED flashlight and a power button to turn on/off the flashlight and powerbank.
Functionality & Performance
I've been using this unit for like 3-4 days now and I must say that it did dissapoint me a couple of times but given the price, the performance and the quality is easily acceptable.
Before I started using the powerbank, I charged it to 100% using a Samsung OEM Charger and quite frankly, it charged pretty quickly compared to my other 10,000 mAh powerbank. I didn't get a chance to use the powerbank for next two days and it did hold up nicely too. Clicking the Power Button on third day, it did show me 100% on the inbuilt LCD Panel (with bright blue backlight). Once connected, I was able to charge my iPhone 6 Plus from 10% to 100% in around 160 minutes (2 Hrs, 40 Min). It is important to mention that both the USB outputs have different specification, the one on the left has 1 Amp while the other one has 2.1 Amp output. During my iPhone charging, I was constantly connected to 2.1Amp output. Now, I know that an iPhone may not charge at full 2.1A rate, but if it took 160 minutes, then I'm assuming the charging rate was at approximate 1.1A which is a bit dissapointing.
To check the output of both the ports, I connected an USB amp meter next time and charged the device back to full. For verifying simultanous charging of 2 devices, I connected my S6 Edge+ and Nexus 4 together. Here's a summary of the result:-
The result clearly shows that the 2.1 Amp output doesn't deliver upto it's claims although, my S6 Edge+ was charged faster than the iPhone (about 125 minutes). Another thing that I noticed is that initial drop in the % (displayed on LCD) is much faster but it gradually slows down. So do not worry if just after the first full charge, the value drops to 60%, it did hold up more than 2 times to charge my S6 Edge+ easily. Another good thing about it is that the charging rate isn't affected much even when two devices were charged simultaneously.
About the flashlight, there's nothing extraordinary about it. It's just a casual flashlight for emergencies, do not depend on it while going for a camping or any other dark places.
Pros & Cons
Pros:-
- Good Build Quality
- High Capacity
- Small in size
- Built-in LCD Panel
- 2 USB Outputs
- Built-in Flash Light
- 2-in-1 USB Cable
Cons:-
- Lower Output
- 1 in-box Cable
Overall, it's a decent power bank at a decent price. Even though this one is just 10,000 mAh, MobilePal has one for massive 20,000 mAh battery at just $30.
