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

Another cool feature of the XTAR PB2S Battery Charger is the fact that you can use it as a power bank. It’ll charge any device as you use the standard USB output port and use your own charging cable. The output voltages that it can manage is QC3.0 & PD3.0 (5V 2A / 9V 2A / 12V 1.5A). Men hvad er TC / CC / CV? Det er en trefaset opladningsproces af Li-ion celler, som holder cellerne i god tilstand, ved kun at oplade med passende strøm i hver fase og afslutte opladningen på det korrekte tidspunkt. You decide the PB2S capacity. With two 21700 5000mAh batteries, it has the largest capacity of 10,000mAh. You can also use two 18650 3600mAh batteriesto get a capacity of 7200mAh.

PB2S has two sweet details. One is the ribbon added to the channel. When you remove the battery, you only need to pull the ribbon up, and you don’t have to dig the battery by your fingers. This will protect the battery and your fingers. During the charging process, the thermocouple thermometer had been connected and the cover of PB2S wasn’t removed. When charging to 65% capacity, the charging power is still close to 15W. At this time, almost reaching the equilibrium state of heating and heat dissipation. Reading the temperature of the two batteries, respectively at 33.1 ℃ and 33.7 ℃. The temperature of the two batteries is close, indicating that the PB2S balanced well in controlling the dual-slot charging. ADVARSEL! Celler der er afladet under et specifikt niveau kan blive uopretteligt skadet, til et punkt hvor de ikke kan genaktiveres. Undgå dyb afladning af Li-ion batterier, da dette kan reducere deres levetid og kapacitet betydeligt, og i værste tilfælde kan de fuldstændigt svigte. The slots are only designed for 18650, 20700 and 21700. The negative end is spring loaded and handles lengths from 63mm to 71.5mm. With two batteries the charger increased the input QC voltage to 9V and maintained a high charge current.Insert one or two cells and connect the USB device, the charger will automatically charge the external USB device. The output supports most of the fast charging protocols. In case your device does not support fast charging, by default the output current and voltage of the charger will be 5V 2A. If the device supports fast charging, the charger will adjust the output power according to the device in question. The maximum output power is 18W. The PB2S is an excellent battery charger, but it also doubles up as a power bank that you can safely use to charge all your portable devices. It gives you the option of two output ports (Type-C and USB-A) so you can simultaneously charge two devices at the same time! The PB2S data shows a slight deviation from the tester. Taking into account the input and output status, the internal resistance of the charging cable and other factors, the reading is relatively accurate.

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.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. The PB2S portable charger/power bank is the latest offering from Xtar andis the big brother tothe PB2, offeringmore options than its smaller sibling. Many thanks to Xtar for sending this for review. In the box Using two 18650 batteries of other brands for testing, the PB2S can also start the PD3.0 protocol. The input voltage reaches 12V, the input current is close to the nominal 1.5A, and the input power reaches 17.78W. Fast charging is also achieved.
