Why Macbooks? Is Apple friendly towards people who replicate their connector interfaces? Or are Macs the only popular device out there where people wish "I wish I could carry an extra battery!"?

They can't put an actual wall socket on it, and they already have USB. If they're going to put one laptop port on it, a Mac port is the obvious choice because it's the largest market.

I am guessing they have licensed magsafe from Apple. Pretty sure they would get a call from Apple lawyers otherwise. There are universal chargers and batteries with all sorts of connectors which are not patent encumbered. Kind of makes me wonder if Apple would cooperate at this stage and then consider buying the company later.

Apple doesn't license MagSafe to anyone.

> note it does not charge the internal Macbook battery. Instead BatteryBox feeds power directly to the Mac in an effort to minimize the number of cycles (and stress) on the internal battery.

Is this something that any power adapter does? Is there something in the way they have it connected that does this?

This technology, if legit, is I think a very good example of where software patents can add value. The future of this technology isn't a little $139 backup battery for Macbooks. Rather, its licensing the charging algorithms to every battery charging controller manufacturer on the planet. One can imagine that over time it might be a good idea for a company like this to vertically integrate and start producing its own batteries, but it's going to be a long time before they have the capital to take on the Korean/Japanese companies currently playing in that space. The alternative might be to angle to get bought by an Apple or Samsung, but that's probably not what's best for the industry. There's a lot of value to R&D companies like this that can focus on a specific niche without having to rely on some vertically-integrated conglomerate to get anything done.

Here is a classic example of a startup launching an Altair Basic with the potential produce a Microsoft-like giant. Incidentally, I think this is also the first father/son team we've funded.

What is the strategy for when Apple disallows sales based on the Magsafe adapter? This happened to HyperMac (now HyperJuice) batteries back in 2011. I still have mine, ordered before Apple lawyers went after them. It's wonderful. Edit: Adding link to Wired article: http://www.wired.com/gadgetlab/2011/01/hypermac-is-back-with...

It's a battery technology company. This is their first product.

They're making some pretty strange claims about capacity and number of cycles. In electric RC heli circles, batteries come along once in a while claiming to use previously unknown techniques to improve the performance of existing cells and a few gullible people buy them. They never deliver on the promises. People who make (established) battery management circuits understand very well how to care for the cells, and cl…

Yeah, it's obviously snake oil. If you had a technology that increased the charge-cycle lifetime of a battery by any substantial amount, you wouldn't be marketing a stupid plastic box for mactards. You'd be cashing billion-dollar checks twice a day.

if you read the article, you'd see they're working on OEM deals to get the tech into batteries across the board. The Box is just a nice consumer demo so people can get their hands on it now. Actually a pretty smart PR move.

Also, the patent: https://www.google.com/patents/WO2013142964A1

I don't understand the need for snark. It's a valid point. The main selling-point of their first product is that it can power MacBooks but if Apple cracks down on them for using the MagSafe adapter then this product will no longer be useful for its intended purposes.

And the selling point of their first product is a non starter, unless apple changed their MagSafe policies.

Maybe this feature was a bit underreported: the current line of Lenovo's Ultrabooks, the ThinkPad X240/T440s allows for hot swapping the battery pack while running on a secondary built in battery. Adding up to 23.5 Whr built in plus up to 72Whr per battery pack.
