The week in gadgets: A battery backup, retractable iPhone case and simple coconut opener

4 May 2015

This week in gadget happenings: A battery backup with two USB ports, a brain-machine interface for your SmartPhone and, at long last, a decent coconut opener.


Consumer tech company Fluxmob designed the original Bolt to be the world’s smallest combined battery backup and wall charger. While retaining that product’s selling point, it has sweetened the deal with the next generation Bolt².

A 2.4A battery backup and charger, the gadget now features two USB ports and packs enough juice (6000mAh) to charge two smart devices simultaneously. And like the original Bolt, it fits easily in its owner’s pocket or bag.

Bolt² currently only supports North American plugs, but it can be used internationally with a standard plug adapter. Fluxmob are currently seeking backing for the product via Kickstarter.


Until now, this was the only way to open a coconut. But that’s all changed thanks to the Cococrack, a new appliance that makes cracking open a mature coconut simple, quick and clean.

The Italian-designed gadget includes two basic tools: a cone-shaped corkscrew and a cutter, allowing users to either open the fruit to get at its water or remove the coconut shell completely and slice up fresh pieces.

“I love fresh coconut, but if you’ve ever tried to open one you know it’s really difficult,” said inventor Valerio Canetti in a statement.

“I wanted to open one and I tried everything from a hammer and screwdriver to a saw. I went to the kitchen gadget store and even the hardware store, looking for a tool. It’s a frustrating experience and you can really cut yourself if you whack it with a machete! That’s why we developed the Cococrack. It’s such a simple and safe way to enjoy a coconut.”

The company has also released a demonstration video that, as well as illustrating what the appliance can do, also warns of the hazards of trying to open a coconut with a chainsaw.


RTKWare is a unique positioning technology module that combines a multi-constellation receiver with an integrated antenna, making it 100 times more accurate than a standard GPS.

GPS devices found in our phones or cars work with precision of meters, which is grand if we’re trying to find an address but not accurate enough if we’re looking for more fine-tuned uses. RTKWare tech makes GPS far more accurate, opening it up for a variety of new uses.

The company gives the example of an American football player wearing its U1BR model, a low-cost, multi-constellation receiver, on their arm. The GPS data is received and sent to a laptop, meaning coaches can record the total distance the player has run, as well as detect patterns.

The company is seeking investment via Indiegogo.
