Review of the Phondly EnBo PU battery pack

Review of the Phondly EnBo PU battery pack, a USB rechargeable battery for Lego Powered Hub (Control+).


If you know the Powered Hub, you know that Lego doesn’t produce any rechargeable battery with this hub. The EnBo PU Battery Pack from Phondly aims to solve this problem with a usb rechargeable battery and stable Voltage. This review presents the prototype that Phondly sent to me, which plan to launch soon a crowdfunding campaign to mass-produce it.
