#ConcreteCharger: A Cement Block That Can Charge Your Phone Wirelessly


#ConcreteCharger, a product developed by O’dea Design, is a simple and stark cement block that wirelessly emits a charge to phones placed on top of it (via Fast Company). The wireless induction charger works with devices like the LG Nexus 4, Nokia Lumina 920 and Samsung Galaxy S4, as well as with various cases and dongles widely available for iOS devices.

#CONCRETECHARGER: The triangular base is crafted from a 9000psi concrete mix and is contrasted with a soft cork top.

According to the developer, programmable NFC tags are incorporated into the tops which can be used to change ring profiles or perform other tasks such as launching an alarm app when the NFC-enabled device is laid on the charger on a nightstand. The block is being offered in two options i.e concrete with cork and black cherrywood with felt, selling for $549 and $449 respectively.

    Poor business model. Half of their costs are probably locked up in shipping due to the necessity to move low volumes of blocks of heavy cement. Why not buy a cheaper model that does the same thing and then hollow out a $10 patio block, throw on a cover and call it day. Perhaps more importantly, what’s the point if you have to connect a dongle or an excessively large case?

    Wireless charging might be cool if I could walk into my bedroom and have my phone charge no matter where it was located without a large case or dongle.

    Yeah seems a bit excessive, they could of made a pad, thats a lot lighter and less damaging to your foot or furniture if dropped.

  • Shipping: Only $500
