The Boy Scouts weren’t joking around when they said, “Always be prepared.”

The truth is, danger — be it theft, violence, getting lost in the middle of nowhere with no cell reception, or the zombie apocalypse (hey, it could happen) — can happen at a moment’s notice. That’s precisely why you should always keep a couple pieces of safety gear on hand at all times.

A Swiss Army knife is a good idea. Another one is 1TAC Safety Charge, a multipurpose charger that will keep you armed and ready during an accident or mishap.

Small enough to fit inside your jacket pocket, this charger comes with a built-in FM radio to keep you in constant communication with the outside world, as well as a USB port for charging your smartphone or tablet. There’s also a built-in emergency flashlight, which is perfect for when night falls. And, if misfortune strikes, you can press a button to emit a siren that will definitely attract attention.

BMW is betting on a better battery.

On Tuesday, the company announced it’s teaming up with Bay Area-based Sila Nanotechnologies (known as Sila Nano), and promised electric vehicle (EV) battery improvements within five years.

Sila Nano wants to improve rechargeable lithium-ion batteries by using silicon instead of graphite. The company and BMW want to incorporate the technology into EVs by 2023. 

Gene Berdichevsky, CEO of Sila Nano, said in a call Tuesday that his tech is “highly scalable” and can be dropped into existing manufacturing facilities — such as a BMW battery factory. Last year the German car company sold 100,000 electric vehicles. Read more…

iPhone wireless phone charging comes at a cost: your battery

TwitterFacebook

Wireless cellphone charging on the iPhone X and 8 sounded too good to be true. We knew there had to be a catch. 

And here it is, as ZDNet contributor Adrian Kingsley-Hughes pointed out Monday: The battery gets run down much faster with the wireless method, as compared to cable charging. It’s more wear and tear on the battery, and eventually it won’t stay charged for as long as it once did.

What a bummer.

Kingsley-Hughes determined — based on Apple’s claim that an iPhone battery is “designed to retain up to 80 percent of its original capacity at 500 complete charge cycles” — that his phone would hit 500 charges in about a year and a half. Most phones are expected to keep a charge at 80 percent for two or three years of use.  Read more…
