thanks deadp1xel for your feedback.
well, i've done more research on mophie and anker. confusing, as both companies have their own sets of "issues" and neither is entirely up front about all their specs, etc. Here's a summary of what i found:
Anker:
they are confusing as their newest and greatest product is actually their 12000 mAh model, the 2nd Gen Astro3 unit. Problem: they started with the black version, non-2nd Gen, then made a 2nd Gen WHITE unit, but still were selling the older gen black units! this caused massive confusion in the marketplace as folks would just place an order and selected the color they wanted without the site explicitly stating that black is older gen and white is newer gen! this does indeed make a difference is that the white 2nd gen (newest) has 3 "smart ports" and not "1 smart and 2 regular ports" (black older gen has merely 1 smart and 2 regular ports).
furthermore, their phone support person told me this, which i do not believe is entirely true:
- "... the 2nd Gen Astro3 uses "lithium ion batteries", which is far newer than the lithium polymer batteries that we use in our "20,000 mAh 2nd Gen Astro Pro2" model!!! ..."
Note carefully that they both use 2nd Gen in their model names, but the Pro2 20,000 mAh just says Astro and not Astro 3. Confusing?!? Yeah!
I do not believe his statement is true. i did some research online but the info i found were confusing as well. it is not clear that the "2nd Gen Astro3" used different battery technology than the "2nd Gen Astro Pro2" as he stated. i believe that he might be misinformed. he made other mistakes in the names of the models as well during the call, maybe he's just not detail-oriented?
there is also confusion as to which Anker wall transformer is optimal for the 2nd Gen Astro3 12,000 mAh model, as they actually sell Anker wall transformers with high Amperage outputs (not run of the mill low amp output typical cell phone transformers). their "Combo" packages appear to possibly sell the older gen 12000 batteries, but it is very unclear.
Anker does appear to take very seriously the differences in the handshakes between iPhons and Samsung Android phones! hooray. this is essential for those of us using non-Apple devices, as these handshake protocols do make a difference in charging appropriately.
Mophie:
they seem to be very very much Apple-centric and Apple oriented! Android seems to be almost an afterthought to these folks. This may be an issue as they focus far more on compatibility with Apple devices and seemingly only deal with Samsung/Android devices as an after thought. This is obvious in that Mophie offers up very little technical information. Their so-called manuals are minimalistic at best. Strange. They do NOT mention anywhere that these USB charging ports on their batteries are "smart" or not smart! Well, it makes sense to assume that they are only going to toot their own horns IF these are smart ports, right? If these are NOT smart ports, then they're just going to keep mum about this point, which is exactly what they are doing. On the other hand, users have reported that Samsung devices charge fine with Mophie products. Then again, reading users' reviews on Mophie will likely result in reading mostly Apple device users' reviews, not Android device owners' reviews. Note that Apple stores sell Mophie.
It is disconcerting that when i called Mophie's Customer Support phone, they have no idea what "smart usb" ports mean whatsoever. They are VERY Apple oriented! They started a tech ticket to try to answer that question. Strange that they don't have an faq with that answer, right?
