What's the best iPhone 4 rechargeable case

I'm buying a rechargeable dvd player, what's out there (Screen size, A & V quality, Cost, Functions)? I've tried searching the web but most sites do not list battery life, screen size or even most known brands--some would list anything but rechargeable dvd players! Thank you for your assitance!

i have a gadget that is powered by a single unit 3.7 li-ion battery. now i want to lengthen the working time, so would adding another IDENTICAL unit in parallel *normally* do it1? any caveats to that?

The 10v rechargeable battery is for Lego Mindstorms. I didnt buy an additional transformer because I have a transformer which already has a 9v or 12v dc output.

It might even be better for the environment, with fewer discarded batteries in landfill.

...possible problems? I bought myself some Energizer rechargeable battiers today thinking that they'd be perfect for the mouse, which keeps draining batteries (the drain of the batteries is normal, but this will just save me having to buy anymore). However, the AAA batteries didn't work.. When I...

...toy when a ordinary 1.5V battery does? The same rechargeable, fully charged-battery (2500mAH) works on my digital camera all the time. But on a toy train (run by a dynamo), it refuses to run. When I put a ordinary 1.5V dry cell battery of the same size/voltage, it works. Aren't these...

I have a Duracell wall charger which holds 4 AA or 4AAA or 2 of each. What I want to know, is if I can put a different brand of rechargeable batteries in that charger without it damaging either the batteries or the charger. For instance putting rayovac or energizer rechargeable batteries into...

My digital camera uses a rechargeable lithium-ion battery pack, I do NOT have anything for it. I do however have a USB that fits, will this work to charge the camera? Thank you

...to recharged again? Will the battery memory thing affect the batteries if I recharge before the batteries are totally flat? The 4 batteries are the 6 hour quick rechargeable type and are use for my camera.

Almost all of my home electronics run on AAA batteries. Is there a web-site, or store, where I can find rechargeable AAA batteries, and chargers, with discounts on BULK battery purchases? What is a good price for a battery charger, as well?

I have a TI-83 (not plus) graphing calculator and I want to know if it's safe to put some of those rechargeable Energizer batteries. So I won't have to keep buying new AA batteries. Please help...and thanks! : )

I want to get an Ematic MP3 with Digital Camera but I want to know 2 things. 1) Does it run on a rechargeable battery or a watch battery type thing? and 2) Opinions on it...it looked really great to me!

I have a Garmin Forerunner 301 and it's missing the AC adapter so I cannot charge it but it does have a usb port. What I don't understand is why I need an AC adapter to charge it when a computer can do the same thing because both have a usb support system. Can someone explain to me why this may...

I am getting ready to go on camera safari to Africa. I am looking to buy a new slr digital camera with changeable lenses. In the bush for some ten to telve days without power,I can't take re-chargeable battery cameras. So, does anyone know of a decent camera (under $1000) which can use 'regular'...

Hi, I just recently boat an RC boat. After charging the ni-cad battery for approx. 2hrs, the boat didn't work. The instructions state that the battery should be charged for 5 hours. Should it make a difference if I only charged it for 2hrs? Or do you suspect there is an issue with the...

I have a pair of "Ultra" brand 850mAh rechargeable batteries. They are nearly 10 months old I would guess and have been recharged nearly every 2 days. I also have a pair of 500mAh batteries that came with my headphones. Ok... The 500s still charge pretty fast and the 850s used to take about...

I bought 2 pairs of rechargeable AA Nimh batteries in September and have used them around 8 times since. The batteries are now showing end of life signs. They start to get discharged within 10 mins of use and also if i charged them and kept, the battery totally lost its charge while idle within...

I know you can not recharge nonchargeable, but I was wondering what internally prevents this, and how rechargeable batteries are able to be recharged.

...they have 40000 or more miles on i? This has been the best car but, I am concerned that there might be a problem with rechargeable batteries going out after the warranty expires. I assume to replace them would be very expensive. But, the true is I just don't know about the reliability of the...
