Rombica NEO AZ120S Quick: portable battery review with Quick Charge 3.0

Manufacturers of mobile electronics make a lot of efforts to increase the battery life of smartphones, without harming their ergonomics. It turns out so far not so. Neither the energy-efficient software of the new versions of Android, nor high-capacity batteries can save users from having to carry external batteries with them.

On the contrary, the assortment of such seemingly simple devices as power banks is increasing - more and less functional models appear. Probably one of the important features of portable batteries in 2019 will be support for Quick Charge 3.0. As part of this short review, we will introduce the Power-Bank model, which is equipped with this feature and will most likely be in favor with users. It will be about NEO AZ120S Quick from the manufacturer Rombica.

Impressions of acquaintance with the NEO AZ120S Quick battery

The external battery from Rombica is an aluminum beam weighing 254 grams. The power bank has been assembled perfectly - the device cannot be blamed for lack of strength or flimsyness. The weight is impressive, even when compared with other power banks - for example, Expert NBE-PB-10-01 from Nobby is a quarter lighter. But just think about it - 12 mAh! The problem with a constant lack of battery will be solved for at least a week - for this you can tolerate an additional 250 grams in the lining of the jacket.

At the end of the portable battery there are 4 connectors - 2 input and 2 output. You can recharge a couple of mobile devices at the same time, but in Quick Charge mode only one gadget will be powered. At the second, charging will go at the usual pace. The power bank itself will succeed in recharging both the MicroUSB cable familiar to Android owners and the 8-pin Lightning. The first, by the way, is included.

There is an indication that makes it clear how much charge is left - it works correctly, does not lie. To check the charge, just press the power key, which is located on the same end as the connectors. The indicators light steadily when a mobile device is connected to the external battery.

After connecting the gadget to the power bank from Rombica, charging the mobile phone should start automatically. An exceptional case is when the smartphone is in deep discharge. If the battery does not start automatically, you need to try to "push" it by briefly pressing the "Power" key.

Tests and Tests

We started testing the NEO AZ120S Quick with a Sony Xperia XZ2 Compact smartphone that supports Quick Charge 3.0 fast charging. Using an external battery from Rombica in just half an hour, it was possible to fill the battery of the mobile device almost half. Note that recharging is equally fast both from the power bank and from the network. Exact measurements are in the table below:

Upon reaching 80% charge on the mobile device, the recharge speed is significantly reduced. At 88%, the current dropped to 0.64 mAh, the voltage was 5.19V. You don’t have to worry - this is one of the features of Quick Charge technology, which helps protect your mobile device from overheating.

We tested with NEO AZ120S Quick and other devices - those that do not support Quick Charge 3.0. Doogee Mix 2 has a quick charge function, but the technology is different. The battery of this gadget from the Powerbank Rombica filled up to 54% in just 30 minutes - with a capacity of more than 4000 mAh. Impressive!

The last smartphone that participated in our experiments was the Samsung Galaxy A3 (2017). This device does not have a quick charge function at all. Using NEO AZ120S Quick, his battery was filled in 1 hour 35 minutes. The same time takes charging from the network.

How Safe is NEO AZ120S Quick?

So much so that the manufacturer has made safety in the list of the main advantages of the device. According to Rombica, the portable battery is provided with a multiple protection system to safely charge devices. Obviously, it is this system that corrects the current strength and voltage level in accordance with the degree of fullness of the battery. In the process of recharging, the power bank does not overheat - there are no prerequisites that the gadget that is connected to it will repeat the unenviable fate of Galaxy Note 7.

To summarize

Rombica's portable NEO AZ120S Quick battery recharges mobile devices with Quick Charge 3.0 up to 2 times faster than a regular network adapter. But this does not mean that for owners of smartphones that do not support fast charging, the accessory is useless. Powerbank at 12,000 mAh is compatible with all gadgets and will definitely not be an unnecessary accessory for a user who is used to using his device “to the fullest.”

At the time of writing, the cost of the NEO AZ120S Quick model in the official Rombica store is 1,990 rubles. But if you apply for a purchase with QUICK2018 promo code before November 19, 2018 , you will get a discount on a portable battery - 20%!
