here's how we make cheap external batteries here in Romania.
this is a DIY concept so if you're not that type of person this may not be for you.
Anyway you must get yourself a sealed acid-lead 12v battery (they are built in the same way as a car battery but smaller) from an electronics shop. They are cheap and come in various sizes. If you want more juice, just buy 2 or 3 of those and couple them in parallel.
Next buy a 12v-220v converter like the ones used in cars. Those that are connected via the cigarete lighter. The smallest cheaper model you'll find will do the job right as long as it can provide 30w.
Don't connect the shift to the batteries, don't be tempted to do this, even if apparently the shift needs 12 v and those batteries supply this voltage. Use the converter.
Now, as you may guesed, simply connect the batteries to the converter and the shift's charger to the converter's output. The converter will suply about 220v at it's output. That's good and that's desirable. Even if your country may use standard 110V values at it's sockets, buy a 220v converter instead.
Now you got a bulky, ugly looking external battery. What's the fun with it?
Well here's the good part.
A standard external battery will give you about 2-3 hours of usage because by the time this is over, it's voltage output will drop from it's nominal value to somewhere around 9-10V. The battery will still be able to provide a fairly large amount of current (amps) but however by this time the shift will be powered off because it needs a nominal value of 12 v (+/- 0.80V) to work (it's internal converter needs it, and has a small tollerance about variations in this voltage). So, 2-3-4 hours of usage, then recharge.
The home made external battery has the following advantage.
After some usage (couple of hours - depending on how much big is the battery you use) the output voltage of the cells will drop. This is normal, and this will happen like the case with standard batteries. BUT you have that converter hooked up. If the converter needs 12 V to supply an output of 220V ac, if you apply only 10 V (the voltage on the battery has dropped because of usage) it will supply only 180V ac. (an estimation). This is well under 220 v. BUT the shift will still work. Why? Here's the cool part. The shift power charger has a nominal imput voltage of 100-240 V (it is rated on it's sticker as the imput voltage). THIS MEANS IT WILL SUPPLY THE 12 V OUTPUT FOR THE SHIFT AS LONG AS THE INPUT VOLTAGE IS SOMETHING IN THE AREA 100-240 V ac. So the converter supplies 180V but that's ok, the shift will still work. So you use it for a longer period of time. When the battery is flat out and has somewhere around 7 volts the converter will supply somewhere under 100v or will stop to work because the battery will also have not enought current (amps) to run the converter's main circuitry or to supply the shift's power requiests.
There are some things that must be said about the eficiency of this method. First you use 2 converters one will raise the voltage from the external batteries ( - your car converter) and the other will lower the voltage to the 12v required by the shift ( - your shift charger). These, both have an eficiency factor. Because of the tehnology used you will have a general factor of about 85%. The rest will be lost in the transfer as thermal heat or EM field radiation.
Still you should get 30-50% more juice then a similar capacity comercial product . And it's more cheaper to buy.
You may achieve the same results if you buy a converter...aah...and a car. Car batteries will provide some good dozens of hours for the shift to work.
That is smart!
But too bulky for me.
yep it's bulky. I'll use it on small camping vacations when a longer battery life is required. No way i'm carring this battery with me as a simple replacement.
yep... I've made one already.
Introducing the shift external battery version 1.0.0. At a hefty 8 kilo it is made for the strong people. It is practically a mobile power house composed of two 12V / 15A acid-lead batteries and a power converter that can output 150W max at 220V. It should give the Shift some 30h of continuos power at maximum requirements. It can also be recharged or powered from anything you can throw at it. Total costs, something around 100 euro. Therefore, shift goes to camping along with my asus eeepc. Hope I find an WLAN enabled forest or something.
Shift external battery version 1.1.0 will use prismatic Li-Polimer cells linked in a matrix and capable of delivering the same amount of power but at 1,5 kilograms. This will be expensive as hell.
sorry, i was probably too amused with my creation and double posted.
you should try this with a battery like first robotics compition uses not that they are that great but they are small batteries like the size of a small boat battery, like 9inches wide by 6 tall and like 4thick but it is like 45 lbs, but outputting a redicoulus 200amps id last like 200 hours continuos max draw...
Dear facdemol ,
It is a very bright idea to mod using sealed lead acid battery to power up our htc shift , i too keen to try out your idea , but how do you recharge back the used acid battery , what charger did you bought and used , can you help me by posting some - many pictures of both your batteries configuration and charger as well ? How long ( hours ) is it you need to fully charge your batteries from flat out ? I dont mind if the set up is looking big and ugly and messy , as long as it is cheap , easy , enough power to last at least 6 hours of solid shift usages , i really now thinking of investing into this . So , please help out and assist in any way possible - will you ? Thanks and best regards to you -

Dear facdemol ,
What charger are u using to recharge your diy battery ( volt and amp ) ? And how many hours it take to fully charge both of your diy batteries ? I am keen to try out your idea as today i have found many cheap sealed batteries sizes for sale in my area and it fits my usage requirement of just 6 to 7 hours of continious shift usage . Thanks and regards - jimmunsw
Right here goes I know we have the DIY charging thread which I must say thanks for, because the information supplied there helped me to make this possible, I don't think anyone has done this before and if I'm in the wrong forum can somebody move it please, I have a transformer and I like to go out camping a lot so I wanted to charge it whist I go away for a couple of weeks. Riding my bike through wales .
I can't charge the transformer whilst the panels are charging the gorilla but I can charge my phone HTC Desire Z.
..I have a power gorilla (a mini gorilla should also work might need to buy car socket adapter though.) The gorilla supplies the appropriate voltage 12 volts minimum to charge the transformer, i'm also using the 22100mah battery in the gorilla to store energy from my 2x freeloader supercharger solar cells.
First the solar charger, I got a Y power supply cable from amazon. 2 x male USB to 1 female USB, these connect to the panels then the female USB socket has a USB to DC barrel connector cable like the one on a router. This then goes into the power gorilla to charge it. The gorilla recognizes the solar panels charge and displays it on the LCD.
I then have the car socket adapter which came with it connected to a 12v car charger with USB 2.0 output (the gorilla pad adapter for ipad won't work.). Then connect the transformer USB cable into this and select 12 Volts on the gorilla.. Voila! The gorilla charges the tablet, making the little charging little noise to confirm and the icon changes, you can also charge your phone at the same time.
I'm not trying to sell any of the items quoted in the topic i just hoped it might help someone out, One of my first proper posts so go easy guys, thanks. b
Sent from my Transformer TF101 using xda premium
Always cool to hear about solar options. I do a bunch of AT hikes each year, maybe my TF will take the trip next time!
diy is awesome. heres a thaught. with more solar power , battery,a few electrical supplies and the hardware in the gorilla charger we could have one heck of a charging system for small eletronics.
You have to calculate everything in watts. Do the math. Figure out how well it will work. And don't forget to calculate the loses. You'll need a large solar panel.
I do a lot of motorcycle camping. I carry a small 12V lead acid battery, a 1 watt solar panel, and of course a 12 volt adapter for my smart phone. My phone has a 1600MaHr battery. It is a power hog and needs a full charge daily. So that is about 6 watt/hours per day (3.8 volts roughly). About 0.5 amp/hours from the 12 volt battery. Add in the conversion losses to charger the gel battery and operate the voltage converters, and you need closer to 1 amp/hour, or about 12 watt hours.
Now the solar panel is rated 1 watt. But those numbers are a stretch and I never see that. And what you do see is only there during perfect weather and perfect alignment, for a short few hours. I would guess that I see maybe 5 watt hours from it with a full day of sunlight. I would need three panels to break even on really perfect weather. Toss in a cloudy day and you are at a loss.
So the solar panel is a bit of a gimmick in this case. I charge the 12V gel cell battery well at home before I head out, and it does the work for me. It holds about 48 watt hours, throw in the solar, so that will cover it for a 5 days or a bit more.
Now I believe the TF101 has a 3300mAhr battery, and two of them in series. Or about 26 watt/hours. If you figure 4 hours of perfect light per day, you need over a 6 watt panel. Figure in the various loses, and you had better have more like a 10 watt panel. That gets pretty big.
I'm thinking about getting an Anker Astro3 10000mAh portable battery for this year. The lithium battery would have a more efficient charge conversion then the gel cell. Plus is is supposed to charge the phone and the tablet. It would be about 38 watt/hours. And much smaller then my 12 volt gel battery. It would charge the phone many times. But it will only charge the tablet a bit more then once.
I should be able to charge it a little from the solar panel, or in my case, plug in into the motorcycle while under way for a quicker charge.
Good idea, thanks for sharing.
And: if it works in Wales, it will work anywhere.
I was looking at this ready built charger - wonder if it will do the trick using a 3.0 USB cord to trickle charge. Or if it needs 12V to kick it off then use the 12V output into a car charger - or just mod the female portion of the car charger to go directly into the charge plug for a more streamlined package.

I was looking for a portable power source for my tablet. Most of the reviews for these devices are not too good and I believe the batteries used are mostly the reason they are not reliable.
I bought two Chinese units called Power Bank with a capacity of 13800mah. I charged them to capacity and after charging the tab from 30% back to 100% they were nearly empty. Since the Tab has a battery rated at 4000mah this does not seem correct.
One unit had five 18650 cells in parallel (blue cells pictured below) and the other unit had two square cells (pictured below) tied together. I tested both battery packs and they were not near the rated value of 13800mah.
When I bought these two units my plan was to replace the Chinese cells with Panasonic NCR18650A cells (green cells pictured below). They now charge the tab twice and my phone 1 1/2 times too. I would rate the unit at about 10,000mah and not 15,500mah. Since the modified unit uses a 1A 5V USB type charger it takes a long time to get these two guys completely charged. But so far they are working great and the modification was pretty easy.
I bought my cells from a distributer here in the US that includes the cells with tabs (in picture below covered by black shrink tubing) at a small additional charge. Soldering on cells will destroy a battery very quickly. The tabs are welded with a machine specifically made for attaching tabs to the cells.
I paid $34.00 for the Chinese unit and $75.75 for the five cells. I hope the internal Chinese logic cards hold up for at least a few years. I know the batteries are good for about 1000 full discharges/recharges.
I use one and my gal uses the other one, they have 120 days use now.

Too funny...13 pounds or 11 ounces, I guess you missed the portable part or maybe you are a world class weight lifter...Thanks for the giggle.
:highfive:
This one worked for me

I got this battery. It comes with a voltage adapter for the GTab2. I found that I actually didn't need it with this battery. However, another 2.1A battery that I have did not work with my GTab2, and this adapter makes it work. I'm hoping it will also make a 2.1A car USB charger work with my tablet as well. I'm waiting for its arrival and will test when I get it.

I have these both for my Galaxy Note 3.
I have this battery because I always need extra power. It fits my needs. It is a perfect match and fit, the quality is great as always from RavPower. Having 2 batteries makes it so I never worry about power issues. This battery charges just like the OEM battery and i think it lasts just a tad bit longer. The dock station is also excellent because I can just put it in at night and its fully charged in the AM. The only slight flaw I see is the it is a little wobbly, but I believe that is because it will charge any micro USB phone that will fit onto it. Both are excellent products.
