A Dece Oasis Power Bank Review
The perfect mix of aesthetics, capacity and speed?
Lenovo subsidiary ZUK has launched its own accessories brand called “A Dece Oasis”, currently the company only produces a small but loud Bluetooth/NFC speaker and power banks, here we will take a look at the latter. The power banks are due to go on sale over the coming weeks, and a price has not been set yet. When they do go on sale you will be able to purchase them over at: Zuk.hk
First let’s take a look at what comes in the box:
The battery has a sturdy white plastic body featuring the brand and logo on the front and the batteries specs on the rear. The top is trimmed with a bronze coloured, textured aluminium collar with 4 LEDs and features 2 x QC2.0 USB ports, a QC2.0 micro usb port and a single button.
Charging the power bank with the provided cable and plug took just under 2 and a half hours, which brought it from completely drained to full. By the end of the charge, the aluminium trim felt slightly warm to the touch but not to the point that I would be concerned about leaving it on charge overnight. According to the provided documentation, the charging efficiency is in excess of 90% and will automatically cut out if it reaches 45 degrees. The LEDs both change colour and brightness as the battery charges/discharges, allowing for a fairly accurate representation of the charge level. All 4 LEDs will start as bright and blue when the unit is fully charged. Over the course of each 25% the battery is depleted an LED will slowly turn from bright blue to purple and then a dim red before going out and the next light starting the process. This means you can calculate the battery percentage to within about 8%.
We ran several 10-minute tests with this power bank, the first was with a phone that supported Quick Charge 2.0 and featured a 3000mAh battery. Over the course of a 10 minute charge whilst the phone was on but with the screen off, the battery increased from 40% to 59% (19%) and showed only a minor change in internal temperature, increasing from 25.6 to 28.3 degrees.
The second test we ran was charging two QC2.0 devices simultaneously, the above-mentioned 3000mAh phone and a 4100mAh phone with USB 3.1 type C. Over the following 10 minutes the 3000mAh device charged from 50 – 68% (18%) and the 4100mAh charged from 50 – 69% (19%).
The third test charged the 4100mAh device from 80% to 90% in another 10 minutes and finally the final 10% took 19 minutes. The much faster charging on the 4100 mAh device could be attributed to its use of USB 3.1 type C.

The ZUK website proudly boasts 12 different safety measures included in the power bank, which include protection from: temperature, short circuit, reset, output current, input overvoltage, input counter, output overvoltage, over-charging, over-discharging, anti-static and magnetic fields. They also state that after 400 charge cycles the battery should still retain 88% of its capacity which is 25% higher than the international standard.
Overall I certainly think this is one of the finest examples of a power bank that has come across my desk. The build quality is exceptional and coupled with a high capacity and quick charge 2.0, it meets my every need for an external battery. I will certainly be keeping one of these handy from now on, and when they come on general sale, I wouldn’t hesitate to buy a few as gifts for friends.
That being said, new options come around all the time, so one must always keep an eye out for the best deal!
