What if we told you that you can make your battery to last at least a 50% more and you'll not notice it in your laptop performance? Dachshund Software has developed a program which can double your battery's autonomy.
Battery Doubler turns off what you are not using and by that way it achieves to enlarge your battery life. Not only does it enlarge your battery's autonomy but it also recalibrate damaged batteries. When you have been using your battery for a long time and you don't care about the charging cycles, its performance becomes lower, but thanks to Battery Doubler you will be able to have it restored.
Before, your only solution to have a decent battery life for your laptop was to buy an extra one. Now, there's a lighter, more efficient, and cheaper alternative: Battery Doubler! Because it doesn't use standard techniques (dim screen light, etc.), but finds out what is not being used and turns it off, such as, for example, the USB ports, you can achieve double the activity without sacrificing comfort.
After using your battery a lot without paying attention to discharge and recharge it fully every time, its performance becomes very low. With Battery Doubler, simply run the recalibration wizard and it does the entire job for you - automatically!
From the configuration window to the battery status indicator features, Battery Doubler excels in ease-of-use. The interface fully respects Microsoft's guidelines and is very intuitive. Because you don't always want to read a 300-pages manual before using a software, you will understand how to use Battery Doubler in no time.
Features:
* Double your autonomy
Before, your only solution to have a decent battery for your laptop was to buy an extra one. Now, there's a lighter, more efficient, and cheaper alternative: Battery Doubler! Because it doesn't use standard techniques (dim screen light, etc.), but finds out what to turns off what isn't needed, such as, for example, the USB ports, you can get up to twice autonomy without sacrifice comfort.
* Decrease recharge time
Your battery recharges much faster if your computer isn't turned on. That's a fact. Let Battery Doubler redefine a few computer facts - with its Turbo Charge technology, increase up to 10% battery recharge speed when your computer is turned on.
* Recalibrate damaged batteries
After using your battery a lot without paying attention to discharge and recharge it fully every time, its performance becomes very low. With Battery Doubler, simply run the recalibration wizard that does the entire job for you - automatically!

* And much more
Battery Doubler features other great functions, such as telling you in hours:minutes your battery's autonomy!

If you need to "power" a circuit, you need an inductor-based voltage booster (again they require active circuitry). These are very efficient, but of course you can't get more power out than you put in... So if you double the voltage, you cut the current (approximately) in half. But normally if you are gong to power something, you start-out with enough voltage... Boosting (or inverting) the power supply voltage is usually a "last resort", like if you need to run something off a car battery and it needs more than 12V, etc.
How much current? That IC will work to generate -3V from +3V, which you could then connect the -3V to the common (ground) of your circuit ONLY IF the battery is not connected anywhere else but to the ICL7660 and the ground of the ICL7660 MUST NOT be connected to your circuit ground.
These links ([1, ](Sprites mods - Run an uC from an AA-battery - Introduction, ucboost)2 ) show a very basic implementation of a switched mode voltage controller using the microcontroller it powers to also drive the circuit. The 2nd link also implements voltage regulation using an ADC pin to control the PWM pin driving the circuit.
So, I was thinking of using a 5-->10V boost converter to charge some supercapacitors aligned in parallel. I was also thinking of using a D-battery and dropping the micro-USB component. But now I have just figured, because the current needed is so small, that I might be able to boost convert a LiPo battery after charging? Is this possible? I can't find any links online?
If I could double or triple the output voltage of a LiPo battery (to 7-12V) I think this would be ideal, even if the mAh falls to something low like 100 mAh. Does anyone have any experience with something like this that might be useful? Any idea on whether there's a cheaper option here?
The A20-BatteryDoubler is easy and quick to fit. Simply swap it back and forth with the standard A20-Mini battery door in seconds.* It is super compact. Even with the BatteryDoubler fitted, the A20-Mini's height and width are unchanged. Only its depth is increased.
Many devices that use AC wall power have a simple bridge rectifier or bridge doubler at the input.
The bridge rectifier will peak detect the AC, creating a voltage that is 170DC with a lower valley due to ripple.
DC voltage will pass through the bridge.
Thus you need an 170VDC source to equal the rectified 120VAC voltage.
Great write up and it's definitely a nice piece of kit. The battery life conundrum is sure a bummer but I think I'd rather play the battery management game and have the spectraband/gain forward. It's a shame they don't have a four channel receiver yet as this would be killer for documentaries or run and gun bags with an 833 / SL2 combo.
thanks for a nice review. Ill be frank and short. The technology of A20-mini and the new Nexus is fabulous - youve said it all and I agree. The reason I would never invest in this could not be simpler : the battery life and a lack of physical settings. All I try to reach is green (rechargeable) approach, great sound recording while not bothering a talent. With only 4 hours of battery life - all these great remote features arent worth a penny. I use SK 6212 txs with great sound, similar RF range, same size and simply amazing 13 hour battery life, with full user menu on tx. Yes, Im limited to 110 db of dynamics only, but it has never put me down yet. I simply figured-out the right "one setting fits all" during hours of homework. One other reason I will never buy Nexus: since it is not a modular syste m anymore: once it goes wrong, you loose 8 to 12 channels, which, for me, would cause a disaster. And no, I dont want to keep another 15k USD nexus unit as a backup in my van. I ĺl stick with 2 channel superslot rxs for a time being.
since i have been using my Nexus, i have, for the most part been able to stick with one battery in the morning, and one in the afternoon.
Nexlink has proved very good at helping extend battery life by powering the transmitters between setups etc. (i appreciate that if you arent doing drama, then this isnt as great a benefit)
Hi Michael, thank you. I work on a Fantasy TV series where costumes are often difficult and tiny, we use a lot of belting, we rehearse a lot and then shoot a half day long (and more) scenes in the same costumes. As of today, I (luckily) never had to change frequencies during the scene - doing a quick frequency scan in the beginning did the job so far. Almost everytime I manage to somehow find a 3.2 MHz of uninterupted hole in the spectrum. (Yes, this is not New York but Prague). With equidistant frequency grid (SEDAC doesnt create harmonics) i usually fit in this hole with all of my 8 digital channels (example: 470, 470.400, 470.800, 471.200, 471.600, 472, 472.400, 472.800 Mhz). Thats why I dont quite understand why woud we need such a large tuneability - my txs still have only 88 MHz of range and it always worked for me. With 13 hours of battery life of SK 6212, I dont need to think about turning off the txs at all, they cover the whole 14 hour day. When our "No.1" actress first wore it, she said she will never go with anything else ? One thing I am jealous for is a greater dynamics of newer systems like A20-mini that will allow me and my crew to go even more lazy and do not care about gaining anymore. Im sure SD will come with bigger battery life in its future units.
