At the very beginning of this compilation, we talked about the 18650 battery, which supported charging using a USB cable. But that copy had a very high price tag. Are there similar cheaper options? Oddly enough, yes. The micro-USB connector has a power source called Rombica NEO X8 18650. What's more, this battery comes with the appropriate cable! That's just a lot of people immediately throw it away. The fact is that the wire has a very short length - about 10 cm. Of course, such a battery can literally be hung under the charger if it is plugged into a wall outlet. But it looks unaesthetic. So, what else can such a battery boast of? Perhaps the first thing that comes to mind is cost. $12 is far from the lowest price. However, it is unlikely that you will find an even more affordable 18650 battery with a charging connector, if we talk only about products from famous brands. Also, someone will appreciate the nice design with the "eight" in the entire battery. By the way, next to the technical information is the PCT logo. This means that high quality is guaranteed. As expected, the product received a charging indicator. With it, you will know in time that the battery is fully charged. However, this battery can be kept connected to the mains for an arbitrarily long time - it is protected from overcharging. The only pity is that the manufacturer does not inform about other means of protection. It is completely unclear whether the battery is protected from short circuit? Can it be used in devices that do not have a power controller, such as flashlights? No, all 18650 batteries can be used in such flashlights. But not all of them are protected from deep discharge, after which the power source can be thrown away. In a word, I would like to get answers to these questions, getting rid of experiences. Unfortunately, this is one of the smallest representatives of our rating. If you want to use such batteries in a powerful bicycle light that illuminates the entire territory of the park, then 1900 mAh may not seem like enough. And this will be enough for some electronic cigarette, not to mention simpler devices. Perhaps this is a great option for those who do not have a specific charger designed for use with AA batteries. However, try to charge Rombica NEO X8 18650 using the simplest AC adapter. You should not use a powerful 2 A charger - it's not a fact that the protection board built in here can limit the current.
