Gelid Zentree USB Charging Station Review

Introduction

As our lives increasingly revolve around portable and mobile devices – smartphones, tablets, wearables, and handheld gaming – so our homes become invaded by a tangle of accompanying cables. Thankfully, most devices – even with a proprietary connector on one end – are USB compatible, encouraging the rise of USB charging stations that can centralise the power needs of your many devices.

Unlike many other USB charging stations on the market, though, the Zentree from Gelid Solutions not only provides a single hub into which you can plug up to four devices, but also a series of nubs – the 3D Tree Array – covered by a removable green silicone rubber top, into which you can neatly stack your devices while they charge.

While the 3D Tree Array is the Zentree’s most visible identifier, the station’s real selling point is its Smart IC chip, which auto-negotiates the best power output for each device that is connected to it, and cuts off power to a device once its battery is full. Gelid boasts that the Zentree can charge four iPad Pros simultaneously in the same time it would take to charge one using the proprietary cable.

The Zentree has been specifically tested using Apple’s iPhones, iPads, and Apple Watch, a wide range of Android smartphones and tablets, plus the Pebble smartwatch, various Bluetooth headsets, and portable power banks. The kit includes four USB-to-Micro-USB cables, but any USB cable can be plugged into the four ports.

“Zentree provides a carefully designed docking surface, 3D Tree Array, which supports multiple gadgets of different sizes: iPhones, iPads, androids, tablets, phablets, smartwatches or really any other USB device. The top is made of a soft silicone rubber, it protects your smartphones and tablets from scratches and slip-off. The Smart IC, a core part of Zentree Charger Unit, auto-negotiates the best output charging power for your gadgets and ensures truly safe multi-device charging.” – Gelid.

Packaging and Accessories

Our review sample of the Gelid Zentree arrived in a plain, unbranded box.

Upon opening the box – revealing the Zentree’s bright green 3D Tree Array poking out of the packaging – I must admit that I was a little daunted, having no idea what the product looked like before I began the review process.

The Zentree includes an IEC C8 power cable, four USB-to-Micro USB cables, and two hooks with adhesive pads on the back. I was happy to find that the USB cables are flat, which is great for preventing tangles.
