Those look to be competent, large capacity charging systems. No doubt I'll have to look into getting one for my ipad, in order to reduce the heat and wear on its internals.
You're not understanding this correctly.
Both the iPhones and iPads are passively cooled, that is, the entire casing acts as a heatsink. It's perfectly normal for the casing to become warm during normal usage.
What is
not normal is the thinking that you should use external power to run the device to prolong its life.
Lipo batteries are killed by cycling and aging. Cycle it once a day for 365 days, and it is worn far more than one that is not.
How does that matter? You can do the same thing to car batteries, eneloop AA cells, dSLR batteries, etc. Keeping it fully charged at all times, as opposed to using it normally, kills batteries faster.
I had to stop using my previous phone due to batteries dying. Once it became last years model, all the batteries I would buy were made months/years ago with limited remaining life (lion tech). They would last a few months at best. Is a $10 iphone battery from a seller based in China, automatically a counterfeit? I wouldn't trust my phone or my safety on it, from the sounds of it.
Then you're not going to buy any electronics, never mind lots of household items and car parts, because a lot of them are manufactured in China. Not everything is counterfeit, but you must use your head. Good quality made-in-China products are indistinguishable from those made in USA and elsewhere.
Here's the deal. A replacement iPhone 4S battery costs less than $6 shipped.

Go to an Apple store and they charge you at least $50, not just to replace the battery, but also to compensate for labor costs.
If you're really paranoid, you can buy more than one unit when you order.
I take for granted that things electronic are made in China, but there is a world of difference between what I can buy at an established retail location, and the bargain types you see on online auctions or other websites. Do you know what I am talking about? Have you read the safety bulletins regarding certain Chinese batteries, making their way into the acquisition chain and destroying products?
If you think made-in-China counterfeit electronics are dangerous, wait until you read the news about made-in-China counterfeit food e.g. eggs preserved with industrial-use copper sulphate because production time is shortened by half compared to those made with food-safe ingredients. Honestly, you should be more scared of your own government's misdeeds than the cr@p that comes out of Chinese factories.
I have been around the world a couple times. Counterfeit electronics is the way of life in many countries, it sounds strange but some big shopping malls have stores that only sell counterfeit products, all out in the open.
I don't need to leave my country to know local stores sell counterfeit alongside genuine - in fact, the nearest mall with that stuff is less than 10 miles away from my house.
Have you noticed how much cooler an ipad or iphone runs, while it is on constant ac charge? Heat kills electronics. While consumer products may or may not overheat during the warranty period, lower temps overall is better for the long term. Everything fails, just a matter of when.
Nope. Those iPhones and iPads still run warm while being powered from external sources.
The last thing I need is to be on a long ride, with the phone giving me gps directions, and shuts down from an overheat state. It is already toasty, sitting inside a tail bag with dual high mount exhausts underneath. Don't need to make it worse than it is.
When you're using your phone as a satnav on a ride, you're not putting it on a car/bike mount, but stashing it inside a bag? So not only is the phone running warm, but the heat cannot leave the bag, making it run hotter than it should. It doesn't take a rocket scientist to realize you're killing your electronics.
Just use your phone/tablet normally, and look at the external power packs as a backup. It's like human aging. Why go to such great lengths to "protect" the internal batteries from aging? They're all going to die anyways.
