Despite the fact that nowadays external batteries are especially popular (almost every second person has them), AAA or 18650 batteries don't go anywhere - many devices work from them, ranging from a wireless keyboard to electronic cigarettes. However, high-quality batteries cost a lot, and if you buy new ones every time, you may find that this is a significant blow to the budget.
And there are not so many centers for the processing of such materials in Russia, which do this without harming the environment. Therefore, as soon as the battery "sits down", in most cases, users throw it into a regular trash can, which is absolutely impossible to do. It would be great to have such batteries that can be recharged like the same external batteries, right?
There are quite a few rechargeable batteries on the market today, but Rombica chargers have attracted our attention. First, in its assortment are batteries of all the most popular sizes - from AA to the battery "Krona". In addition, they are distributed at an adequate price, so we immediately ordered a small box to the editor. And most importantly - the batteries are charged from any USB port.
The NEO line for Rombica is represented by four copies: X2 (analog of AA batteries), X3 (AAA), X8 (18650) and X9 (“Krona”).
NEO X2 is a set of two charged, rechargeable lithium-polymer batteries of size AA. The battery capacity is 1300 mAh (1950 mW • h), they provide a stable output voltage of 1.5 V during the discharge cycle.
The charge time from the USB port is only 75 minutes - and the batteries are ready to work again. You can easily connect them to a laptop or desktop computer, without using a specialized charger. And you can charge the batteries even from portable batteries: charging is fast and without a memory effect. The efficiency of the device is conveniently determined by the LED-indicator.
In addition to two AA batteries, the kit also has two micro-USB cables. With a weight of only 15 grams, this is an excellent solution, especially since charge-discharge cycles here are more than 3 thousand. You can buy Rombica NEO X2 batteries in the DNS online store.
NEO X3 also consists of two rechargeable lithium-polymer batteries, but the size AAA. Due to the smaller size, they have a smaller capacity compared to X2 (400 mAh / 600 mWh), the charging voltage and output voltage are unchanged - 5 V and 1.5 V, respectively.
The kit also includes two micro-USB cables that you can plug into any appropriate port and charge the batteries in half an hour. Weigh only 10 grams, you can buy Rombica NEO X3 batteries in the DNS online store.
18650 batteries are used where large capacity is needed - in portable batteries, LED lamps, even laptop batteries. The low level of self-discharge and the lack of memory effect have made this size very popular, especially in modern technology. Its Rombica counterpart is a lithium-polymer battery NEO X8, which provides a stable output voltage of 3.7 V.
The battery capacity is 1620 mAh (6000 mW • h), more than three thousand charge-discharge cycles. Of course, weighs a little more (40 g), but the dimensions are appropriate. The main thing - no memory effect, 180 minutes to fully charge from any USB-port. And a micro USB cable included. You can buy a Rombica NEO X8 battery in the DNS online store.
Battery "Krona" - one of the most popular power sources for consumer electrical appliances. Although in everyday life we use this size not so often, there are situations where you just can not do without it. In this case, Rombica offers a rechargeable lithium-polymer battery NEO X9 with a capacity of 430 mAh (3,900 mW • h).
A micro USB cable for charging is of course included. Most importantly, even this battery can be charged from any USB-port, and the charging time will be about 90 minutes. You can buy a Rombica NEO X9 battery in the DNS online store.
We are sure that in this assortment you will definitely find a battery or a battery that you need. Take care of our planet and try not to use "disposable" batteries.
