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

When the battery power of the phone is 97% and the Kindle power is 91%, PB2S significantly reduces the charging current to ensure the safety of charging. Let's see the display with a Samsung 21700 inserted in slot n.2 of the PB2S before and after starting the recharge.

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). With two batteries the charger increased the input QC voltage to 9V and maintained a high charge current. 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 Fashionable Lightweight Power Bank

PB2S has three-stage charging (TC-CC-CV). The battery charger uses the float current (TC) to "wake up" and protect the batteries when the battery voltage is very low. After the voltage becomes normal, the charger starts constant current (DC) charging. When the battery is almost fully charged, the charger starts constant voltage (CV) charging, to make sure the battery is fully charged and less damaged. Whether you’re using 18650, 20700 or 21700 external vape batteries, charge them all with the PB2S safely and accurately. Unlike regular chargers on the market, the PB2S utilises a three-stage charge system that has your battery’s best interests at heart. When you slide in a battery that’s low on power, instead of overloading it with current, it gently wakes the battery up with a low current and after the right level switches to constant voltage. There is also an intelligent 0V activation function built inside that safely revives fully drained batteries, thus improving their health.

During charging, the numeric display shows the input voltage, current and battery capacity percentage. When going outdoors, the ability to carry only one battery bank/charger and multiple spare batteries is also a space saver. When the battery condition of Kindle is better, the PB2S can also increase the charging current to get a faster-charging speed. As a portable power bank, XTAR PB2S charges your phone, tablets, mods, or anything else you can use for USB for. PB2S can also charge "low-current" devices such as wireless headphones and USB lights. The slots are only designed for 18650, 20700 and 21700. The negative end is spring loaded and handles lengths from 63mm to 71.5mm.

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. PB2S supports QC3.0 + PD3.0 fast charging, compatible with most phones fast charging adapters on the market, easy to pair and use.
