XTAR PB2S 18650 Batteries Charger, Portable Charger with Power Bank Function QC3.0 PD3.0 Dual-protocol Fast Charging for Flashlights’ 18650 21700 20700 Battery Trail Wildlife Cameras 18650 Batteries

This unit’s built for multi-tasking—charges 18650, 20700, and 21700 lithium-ion cells and doubles as a power bank when loaded. USB-C input/output with Quick Charge 3.0 and Power Delivery 3.0 means fast charging for both batteries and devices. Ideal for torch kits, wildlife cams, or van setups where you want backup power and battery top-ups in one. Digital display shows voltage, current, and battery status—no guesswork. Spring-loaded slots grip cells clean, and the case feels solid with magnetic closure. Compact enough to stash in a gear bag, and smart enough to auto-detect battery type and adjust charge rate. Best used with quality cells—cheap batteries can limit performance or trigger safety cutoffs. 👍 Pros ✅ Dual function—charger + power bank ✅ USB-C with QC3.0/PD3.0—fast and flexible ✅ Supports 18650, 20700, 21700 cells ✅ Digital display—clear readout ✅ Compact and solid—easy to stash 👎 Cons ❌ Batteries not included—buy cells separately ❌ No passthrough charging—can’t charge and power at once ❌ Magnetic lid can pop open if dropped

been a long time user and fan of XTAR chargers, I have the older version PB2C and love it but wanted the 21700 and PD support. The PB2S is a great device, functions as a smart and safe charger for li-ion cells and also can be turned into a great power bank where you can choose the cells you want. I love the QC/PD capability to charge it and that it can also deliver fast charging, I tested and it charged my phone on 9v. Another feature that sets it aside is the low-power function which is rare to find on other brands and super useful for devices that draw little current as most power banks turn off instead of continuing to charge.

Great dual-purpose gadget, in that it can charge two batteries for my ecigs and also use those same batteries to charge a phone (or whatever) by USB. Supplied cable can be reversed to charge the batteries or output to something else. There’s no built-in battery to wear out and no danger of falling for the gross exaggerations of battery capacity that most manufacturers of power banks seem to resort to; you use your own batteries. The hidden LCD is nice but at first I thought it didn’t have one at all! Flaws: the magnetic cover falls off easily so I’ve resorted to sellotape when carrrying it around; 18650 batteries are a little loose inside and can become disconnected if it gets shaken around; there was a pointless ribbon for battery removal that got in the way until I cut it off.

Portable yes, good to use all the time... No. It doesnt show individual batterie charge percentage. Just a duel one. And also its not acurate percentage. It doesnt charge your batteries on the go which is what i got from the description. It has to be plugged in. So if ur out and about it basically just holds the batteries. But if it 18650 then they move about in there so not the best for safety metal rubbing etc.

So, in a nutshell, this is a well-made charger for many LiIon cells including the bigger 21700 type and it also doubles as a power pack once it has some cells in it. Simple enough? What sets this apart is the display though - to charge you plug it into the power source (USB-C) and *then* put the LiIon cells in. The display quickly tells you the level of charge %, the charge voltage and current - and it can use USB-C PD/QC at up to 12V as well. When used as a power bank you also get %charged plus output voltage and current so you can tell how fast your device is charging (pretty fast if it’s an iPad or supports QC3.0). This also helps you spot bad charging leads that don’t support high current charging BTW and you can pay a tenner for a USB current meter as a separate item. The USB-C port supports charging in and out and there is also a single USB-A port for the rest of your stuff… The unit feels well made - the magnetic cover is secure and the build quality feels high, the case is smooth with a non-slip coating and the display is frosted so it looks suitably cool when it is active. All in all it’s about as sexy as a battery charger can be.

Charger drops in and out while charging iPhone. And wont reliability charge batteries. I have contact customer and spoke over email many times, they refuse to accept responsibility and now ignore my emails. Zero product support

If like me you use 18650's in your vape machine(s) then this is a really good buy. Saves carrying about spare batteries AND a battery pack so less to carry in the old backpack.

I bought this and installed 2 X 21700 batteries (Samsung inr21700-40t from nubattery) in it. Using a usb-c to usb-c cable I tested with my OnePlus phone and noted that it rapid charges it and this is a excellent result for me as so many devices can not charge my phone at the higher speed. Further tests with other devices and my test meter indicate its max output (with my battery types) is 2.9A at 4.6v, which is impressive as most struggle to reach 2.0A. I have a few other XTAR products and they seem well made and last well and I'd certainly recommend this as well

Super! Klein, niedlich, handlich. Liegt ausgezeichnet in der Hand, warm-weiche Oberfläche. Angenehmes Arbeitsgefühl. Elektronik tut was sie soll, die Statusanzeige ist eine Wucht!!! Kleiner Nachteil: könnte eine ENTLADEfunktion gebrauchen!

Ich nutze das Gerät hauptsächlich als Ladegerät für 2 Panasonic NCR18650B. Die Ladefunktion kann ich mit normaler USB Spannung nutzen, aber mit meinem QuickCharge Netzteil lädt es, bei 2 Akkus, etwa doppelt so schnell bei 9V und gleicher Stromstärke. Die PowerBank Funktion habe ich mit verschiedenen Geräten getestet. Mein MotoZ Play zeigt schnelles Laden an, bleibt aber laut der eingebauten Anzeige bei 5V und etwa 2,4A. Bei verschiedenen Kleingeräten wie Kindle und Bluetooth Kopfhörer war die Low Power Einstellung hilfreich, da sich sonst die PowerBank ausschaltet. Bei dem Telefon eines Freundes wurde auch 9V Ausgangsspannung ausgehandelt und zum Laden genutzt. Das eigentliche Problem, weswegen ich 2 Sterne abziehe, sind Geräte, die 12V aushandeln. Ich kann z.B. mein iPad Pro nur an dem USB-A Anschluss mit langsamer Geschwindigkeit laden, da an USB-C 12V verhandelt werden und die PowerBank sich ständig ein- und ausschaltet. Selbst bei 100% vollen Akkus schafft das Gerät es scheinbar nicht die Spannung zu halten und geht entweder alle paar Sekunden aus oder das Display flackert. Lässt man es dann eingeschaltet geht es soweit, dass es komplett abschaltet und man die Akkus entfernen muss um es wieder zu aktivieren. Schön wäre noch eine größere Variable Eingangsspannung. Ich nutze gerne mein Laptop Netzteil zum Laden aller Geräte unterwegs, aber leider kann das nur zwischen 5V und 20V Profilen wechseln, lädt also die Akkus dann mit 5V. Ich könnte meine richtige PowerBank dazwischen schalten mit variabler Ein- und Ausgangsspannung von 5/9/12/15 und 20V, daher wäre das nur ein "nice to have".

2 Geräte bestellt. 2 Geräte genutzt mit 4 Akkus. Leere Akkus werden als voll angezeigt und dementsprechend nicht geladen. Nach 2,3 x ab - und wieder anstecken bequemt sich das Teil doch noch zu laden. Lädt dann Akkus "voll". 2 ehpro100 Akkuträger hatten mit den mit diesem Ladegerät geladenen 21700ern das Problem, dass nach 1-2 Stunden die Luft raus war und die Akkus nur noch genug Saft für 40 statt für 60 Watt liefern konnten. Seitdem wir wieder über andere Ladegeräte (und sei es nur direkt über die Akkuträger) laden funzt wieder alles halbwegs... Halbwegs heißt: die damit geladenen Akkus sind hinüber, aber die anderen Ladegeräte bedienen die noch halbwegs. Akkutöter vom feinsten.

Unfortunately, with 18650 cells this power bank is unusable for me as the spring contacts are to loose to hold the 18650 accumulators firmly in place. Because it has spring contacts only on one side, this leads to the batteries losing contact with the bank when it receives even a slight shake. For example when you're walking and holding it, or even when you put it quite gently on a hard surface. When it loses contact, it shuts down and stops charging the phone, and doesn't start charging the phone again when the contact is restored. I bought it for the USB-C PD functionality, but this makes it unusable for me. Now I've added some foam to the other side of the lid to hold the batteries firmer in place (which didn't help) and now ordered some spring contacts to solder to the other terminal of the bank to resolve the issue with contact loss. But if you plan to use 18650 cells, I'd just avoid this bank.

nach 6 wochen hat leider einer der beiden lade-slots den geist abgegeben
