About this deal

Internally the battery compartment is well done with the drawings for the correct insertion of the batteries printed in evidence. Intelligent detection and multiple protections ensure safety. High precision, auto cut-off when fully charged. Three-stage charging (TC-CC-CV) makes batteries healthier. PB2S supports QC3.0 + PD3.0 fast charging, compatible with most phones fast charging adapters on the market, easy to pair and use.

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). The battery channel of the PB2S is perfectly compatible with 18650, 18700, 20700, and 21700 lithium-ion batteries. However, for a protected 21700 cell, it can't fit in PB2S, which is a bit regretful. 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. It took 2h 5min and 21s. Two 21700 4200mAh batteries were fully charged. The PB2S showed an input current of 0A. At this time, the voltage remained at 12V and the charging speed was very fast.With built-in intelligent detection system, when the battery polarity is reversed or the charging channel is shorted, the charger will not start charging, so as to ensure the safety of batteries, chargers and users. Plan on a journey or an adventure? You must not forget the charging gears. For me, I usually take many electronic devices such as iPhones, earphones, iPad, flashlight and camp lamps. Therefore, I need lots of power. But carrying a large capacity power bank is so heavy. How can I deal with this problem? Charging is done simply via a USB-C Cable, XTAR supply this cable (which measures 80.0cm in length) which can also double up us a USB-C output cable to your USB-C device using the USB output port. Over-Current; In an electric power system, over-current or excess current is a situation where a larger than intended electric current exists through a conductor, leading to excessive generation of heat, and the risk of fire or damage to equipment. (Source Wikipedia)

PB2S has OV activation function to revive over discharged batteries. By inserting a battery that is too low, the charger will automatically detect and activate the battery. Especially when the power consumption of my kindle is seriously insufficient, the PB2S can detect that the voltage of the device is low and activate the battery of the device with a very small current, which is also a more intelligent and safe charging method. By charging the battery present in slot n.2, the display immediately shows the percentage of battery charge and the current intensity of 1.7A. USB-C QC3.0+PD3.0 fast charging, compatible with most phones' fast-charging adapters on the market. With a single 18650 battery the charger can easily deliver 0.5A for nearly 4 hours. It shunts down the output when the battery is down to 3V

Product reviews

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. I like the size of the charger and the magnetic lid is easy to open. The charging looks good, but batteries must be able to handle 2A charge current. The voltage and current values are not that precise, but good enough to give an idea.

Recently I noticed that XTAR, a specialized battery charger manufacturer, has launched an innovative product, PB2S 2-in-1 power bank. It can be used as both power bank and Li-Ion battery charger. As long as there is an ordinary cylindrical lithium battery, it can charge various devices outdoors anytime and anywhere, which is very convenient. In the tests I made to recharge batteries in 18650 and 21700 format I obtained good results managing to charge a 3000mAh Sony murata VTC6 18650 battery in about 3 hours (at 1.7A max.) and a 21700 battery in a 4900mAh XTAR in about 3h50min (2A). 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. This feature, combined with the fact that it has a closed shell, makes the PB2S battery charger almost unique in its kind. In the end, it took about 2.5 hours to fully charge a mobile phone and a Kindle from a basic powerless state. The discharge efficiency of PB2S is good. At this time, the remaining power of two 21700 batteries is 20%. The voltage of both batteries is about 3.4V, which is balanced for two-slot discharge. From this, it can be judged that the PB2S discharge cut-off voltage is about 3V, which will not be over-discharged for lithium batteries, making discharge safety.

Xtar gave me two batteries, I can use them here to show the battery space, but with only one of each I cannot test them. 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).

Professionel processorstyret oplader til Li-ion 18650/20700/21700/26650 celler med powerbank funktion Aside from that, I can’t fault the XTAR PB2S, and highly recommend this to anyone who needs both an 18650 battery charger and also uses a power bank.

Uploading

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. 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. 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. The display screen shows the Input voltage, current & capacity percentage (Output voltagewhen used as a power bank) and using the side button you can scroll between cell 1, cell 2 & both.
