Portable power devices to keep your gadgetry perky through a long day’s work come in an amazing variety of sizes and shapes. But I have never before come across a battery that seems designed to snap into a Filofax. And yes, you did just read Filofax.
I didn’t even realise the ultra-thin (just 7.5mm) EnerPlex Jumpr Slate 5k was Filofax-sized until the thought struck me in the middle of the night. I actually got up to check this seemingly daft thought on Filofax’s website (yes, they have one and still exist) – and I was right. The EnerPlex is precisely the same 95mm x 171mm size as Filofax’s most popular compact organisers, and even has the crucial holes for the binder rings. It’s also a beautifully crafted device that could slip just as easily into a jacket pocket or handbag. Its 5100mAh capacity is ample for reviving a fading phone or tablet of any kind.
