    Today's review will be devoted to the charger with the option of a power bank (or a power bank which is also a charger) PB2S.
    Repost from our official reviewer:
    So, what's interesting in this device?
    Well ... it's not a very versatile charger, and a very interesting powerbank.
    Let's start the review, I’ll explain everything there.
    Go? The device comes in a small cardboard box, the equipment is minimal (instructions, yes USB-> USB type C cable). I am glad that the cable supports data transfer.
    The device can be purchased in four color options; I got a red one for the review. There is a soft touch coating, the screen is matte, scratch resistance is noted. A little bit about the operation of the device. The type-c input is also an output, the charger is capable of charging two devices simultaneously.
    The button on the charger changes the readings displayed on the display, as well as activates the output of low current (for charging fitness bracelets, for example, which the device in normal mode may not “feel” and ultimately not charge). The button does not change the modes of the charge current as well as the different outputs of the device. What am I doing? And the fact that the battery charge current depends only on the connected power supply, and the user can not affect this. So if there are a lot of 2 amperes per channel - connect to a weaker power supply.
    During charging, you can connect / disconnect rechargeable batteries. Also, while the device is operating in power bank mode, you can change the installed batteries, the output current in this case does not interrupt (of course, if at least one battery is installed).
    The device is compatible with protected and unprotected 18650 batteries and also unprotected 21700. The 18650 batteries in the device “walk” with active shaking, contact is sometimes broken. The protected 21700 cannot be installed; the length is great.
    The magnetic cap holds tightly and securely, you can lift the device with the batteries installed, it will not come off. The device (and screen) is in operation. A few measurements: An unprotected battery device discharged up to 3.27 volts. When connecting powerful devices, I found that the voltage drops but the device "tries" to give out more current than it can - with the declared 5 volts 2 amperes, I saw 4.4 volts 2.2 amperes. On the one hand, almost 10 watts, and on the other hand, 12% of the deviation from 5 volts is too big.
