I have never owned a powerbank and didnt know much (ok, nothing) about them before researching online. As I am going on a trip where being able to plug in to recharge my devices will be sketchy at best, it seems that having a powerbank would be essential. I decided on the Inui because of its price, compact size, because i could charge both my ipad and android phone- and because of the positive reviews.Overall, I like the Inui powerbank. I like the size. I like its look. I like the fact that it came with a cable i could use for charging (while i had to buy a wall plug to charge it, i had enough cables to cover my device hook up needs). The little bag it comes with is a nice touch though it would have been ideal if it was a bit roomier so i could store my other cables in it. Not a big deal, obviously. I like it that my Inui gives me a numerical read out of its battery. The paw print read out that other Inui have is a cute idea but not helpful. I think it is better to know that i have 20% battery left that ‘one paw pad’.As to charging times for my devices, I think i expected that it would be faster but that is probably just ignorance about the technology (and wishful thinking) on my part. It took 2.5 hours to recharge my ipad that was at 30% and it took 1 hour to recharge my phone that was at 50%. It took 3.5 hours to recharge the powerbank that started at 36%. I dont know if this is typical charging times or if there are faster ones out there but it is worth keeping in mind. For most people this wont be an issue because, if the powerback’s battery is depleted during the day, they can be recharged overnight.As to the number of times I would be able to recharge my phone or ipad on one Inui fully charged powerbank, it seemed like a pretty even swap of power going into my phone or ipad and power going out of the powerbank. (This is where having actual battery numbers versus a pawprint was invaluable). So i dont think i would get much more than a single device fill up per fully charged Inui. However, these Inui battery powerpacks are very inexpensive and compact and it would be easy enough to carry two if, like me, you are not going to be to recharge your powerpack on a regular basis.
