I really liked my trent. I bought one from eBay which was an older model and may invest in the more up to date 2 USB port version which also looks smaller. I use it at home too for emergency charges.
Oh, I forgot to mention that if you sign up for their email list, you may get emails asking if you want to join their beta testing program. I just tested a case for my Galaxy S5 and could have tested a case for the iPad Air - except I don’t own one
I have a Trent and it has worked great. I just don’t like that you have to carry one more thing around along with a cord. I have been considering trying out a mophie case that has the battery backup built into the case. Does anyone have experience with these?
I bought the iCarrier & iTorch from Amazon in Feb. iTorch is smaller, only 1 charging port & battery doesn’t last as long as iCarrier but it worked fine.
I have the newer Trent charger with the 2 ports. It is great. Charges relatively quickly. I bought it for our trip but have used it several times when I forgot to plug in my phone at night. I carry it in my purse all the time.
In the last few days i bought a Morphie Powerstation (the separate battery block which you plug into your phone via your phone charging cable). It’s near enough the same size as my iPhone 5S (but a tiny bit thicker). Not impressed with it so far. It didn’t do much of a charge before it was dead. I think it may need a few charges/discharges itself before getting up to full strength.
Still, it should give me enough juice to get through a day (if i leave the hotel with a full charge on both phone and Morphie).
