XTAR PB2S 18650 Batteries Charger UK USB C Port 18650 Fast Charger Unprected 20700 21700 Battery Charger Two Ports Output Not included Batteries (Black)

Product Information

USB-C QC3.0+PD3.0 fast charging, compatible with most phones' fast-charging adapters on the market. The charger has a very low discharge current when not used, except if the batteries are completely empty, then it will drain them too much. This means it is a bad idea to leave batteries in the charger/power bank when not used. For some small electrical devices, PB2S can detect the condition of the internal battery and use a small current to output power for the devices to ensure full-charge and safety. I tried my kindle. XTAR PB2S takes the portable charger and battery bank all rolled into one. It supports 18650 unprotected/protected and 21700 unprotected batteries. The max length of supporting battery is around 73~74mm.

By inserting the batteries, the device detects them and activates them automatically. The batteries cannot be activated, they will be considered as "broken batteries" and the message "0%, 00.0V, 0.0A" will appear on the monitor. The XTAR PB2S is a portable battery charger with Power Bank function to recharge your mobile devices anywhere and anytime outdoors. It can even deliver 2A from one battery, but only for about 45 minutes. The output voltage is stable, there is no drop when the battery is nearly empty. The charger generally starts at a fairly high current, this may be fine for 21700 and high current 18650, but it not ideal for high capacity 18650.

If you’re a vaper who’s concerned about the longevity of their batteries, the PB2S puts you at ease immediately. With its patented battery balancing technology, the charger makes optimum use of the capacity available while charging your batteries. The PB2S is more eco-friendly. You can use it as a charger for cells and a power bank. You can replace the cells.

Her har vi en professionel processorstyret oplader med powerbank funktion. Opladeren byder på en trefaset TC / CC / CV opladningsproces i den lille in enhed. Oplader 3.6 / 3.7 V Lithium-ion celler af enhver kapacitet, af modellerne 18650/20700/21700/26650. En intelligent indbygget balance funktion styrer op- og afladningsprocessen. Dette resulterer i en betydelig forlængelse af cellernes levetid. Opladeren starter altid med at oplade den mest afladet celle. Når cellerne når et tilsvarende opladningsniveau, ville begge batterier oplades samtidig. Det samme sker ved afladning, opladeren starter med at aflade cellen med højeste ladning, indtil begge batterier når et tilsvarende niveau, hvorefter den aflader begge celler samtidig (Powerbank funktion).

Xtar PB2S Charger

When the charger is off, long press the button to charge low-current devices such as Bluetooth headphones and USB lights. The display will flash slowly to indicate this mode. Then long press the button to close the USB output. When going outdoors, the ability to carry only one battery bank/charger and multiple spare batteries is also a space saver.

Use a XTAR PD3.0 adaptor to charge two XTAR 21700 4000mAh. The USB test meter read the output voltage of the PB2S reaches 12V, the current reaches 1.43A, and the power is 17.13W, which reaches the nominal input of PB2S. Soft-Start Function: The soft start function in a power supply circuit minimizes large startup currents from flowing when the input power is first applied. As power is first applied to a circuit, the capacitors must be charged from zero to their final values, while the inductors and transformers need to have their flux stabilized.

For those who have many 21700 and 18650 batteries, the XTAR PB2S makes full use of the idle battery. It is indeed a very good on-the-go choice. Over-Charge: Charging a battery beyond its full level leads to permanent or temporary damage of the battery. (Source Quora)

While charging, the numeric display shows the input voltage, current and battery capacity percentage. Press the button to switch between the display of the charging voltage and the charging current of the battery in slot 1 and "B1"(battery1). Press again toggles between the display of the charging voltage and the charging current of the battery in slot 2 and "B2"(battery2). Press again to return to the entry screen. Opladere fra andre producenter kan forårsage betydelige temperaturstigninger i celler under opladning. Hvis cellerne bliver for varme, kan det reducere deres levetid. Da Xtar designede PB2S opladeren, valgte de at løse dette problem på den simple måde, ved at forsyne opladeren med strøm fra en ekstern strømforsyning. Dette har resulteret i, at temperaturen på batterier opladet i PB2S ikke stiger med mere end 15 grader. Another feature of the battery charger is the OV activation which revives the batteries that are too low. The OV activation function, which first originated from XTAR, activates some refreshable batteries. By inserting a battery that is too low, the charger will automatically detect and activate the battery. XTAR PB2S beats all the other power banks because you can choose the best quality and capacity of batteries and can replace them as necessary, so it will have a longer lifespan. It also allows older cells to be used.
