I am going to Europe this summer and I need a relatively small portable battery that will keep my iPad and iPhone charged for the long plane rides. What are your recommendations? I have looked at reviews for the HyperJuice Mini and the Zagg Sparq and they don't look promising. Any ideas?
Thank you in advance!
Would any of you recommend the Mophie products?
Most portable battery packs are around 1000-2000 mAh which means fully charging a iphone .5 to 1.8 times
then there are the $100 standalone chargers that are around 6000 mAh those will recharge a iphone around 4 times
If you want a battery pack that will last a very long time between charges, you can get one of these
All you need to do is DIY a few parts to get it down to 5V. (then after that just rig some kind of belt clip (if 1 of them can move a 4 door car 30 miles, then it can power a cellphone for a few days))
If I was going somewhere where I would be without a power outlet for a long time, I will work on building something that can run off of a laptop battery.
Portable battery packs are often way overpriced compared to laptop battery packs. It would be great to make something that can just use laptop batteries (eg find one with the highest capacity at the cheapest price (eg for older laptops), then get the voltage down to 5V then solder it to a USB hub.
PS never use those smartphone cases with the unlt in solar panel. (it causes the phone to also get hot (a student in my class has one)
Get a few of these, perhaps.
