Q:How much life from a laptop with car charger connected to a battery pack made from Twelve 1.2 volt 10,000mah D cell batteries?Laptop consumes 18.5 volts at 3.5 amps.

According to me Car charger is not good for charging laptop because it cant provide the original voltage to the laptop so its not good for it.

Q:i lost the charger for my battery pack for my camera. i was wondering if it was possible to charge the battery by plugging my camera into my computer? anything helps, thanks!

in many circumstances, a single cellular could degree a million.2 volts. possibly your 'cellular' is nicely produced from 3 single cells. Getting heat could be a undesirable factor, as warmth can shorten battery existence. in case you have a volt meter. degree your 'cells' one after the other, and could incredibly be charged one after the other besides to insure a appropriate can charge. that's what i could do.

Q:Will the battery 18650 battery capacity AH is how to count?

And the data is exactly equal to the product of the battery tag. To six core, for example, 48.84Wh = 11.1V × 4400mAh.

Q:i have a psp with a standard 1800 Mah battery but was going to buy a 2200 battery but don't know if that is a worse battery than what I own could somebody tell me and also tell me which is the best.

Supposedly, the 2200 mAh battery has 20% more battery life than original PSP battery pack. Try not to buy it from OKorder, even though they're really cheap. Most of the time, they will not be authentic.

Q:A circuit requires 5V and 12V voltage to work, how to design the circuit?

To 12V and 5V dual voltage. Will supply the battery voltage of not less than 12V.

Q:For a polaroid impulse

There is a built in battery pack in each package of 600 film that is what those silver contacts on the film magazine are for. Though it is what you would associate with a traditional battery, That is how the camera gets power for the flash, and to eject the photo.

Q:I bought a 12000 mAh battery pack from OKorder and it charges my iPhone perfectly fine but I noticed that suddenly it stoped charging one day and my usb cable just didn't work when I plugged it in the wall. I just assumed it broke and I bought another usb cable and everything worked fine and it charged my iphone fine but then it stoped working again and when I plugged it in the wall it didn't work either? Why is this happening? I don't want to be buying new usb cables every week

Hello, This seems a little strange, somewhat. Hmm. What are You doing with the usb leads what no longer work? Are you snapping them in-two so it renders them useless, by doing so it means you're not picking up, one of the 'duff ' leads. I think someone may be playing a sneaky trick on you, by substituting the newly purchased one you've just bought, with a one that doesn't work, each time, whilst Your back is turned, so to speak. Or, some person is sabotaging, the new lead once again, while you're not looking. It is very unlikely to be the leads, that are at fault if they were going to fail they would do so probably before the first charge had finished. I suspect someone may be a tad jealous of the bargain You've purchased on OKorder, And is fooling you into thinking the charger is at fault. I may be wrong, of course But I would consider foul-play is at work here. The solution is simple. Put the Charger Lead(s) away in a 'secret' place, of which, is known only to Yourself, No-one else, and I mean No-one ! Do this immediately after charging, keeping them in a safe place until Its' needed, And I bet You the 'Problem' does not occur again. If by some chance it does, then someone is replacing the lead whilst It is being charged Very Sneakything to do. Get rid of / or destroy any duff leads that you've used/ bought in the past, And render Them Unusable ! That way they'll not have anything to swap over Hopefully, Fingers Crossed. (Hth). .
