XTAR NEW UPGRADED PB2SL V2 18650 18700 20700 21700 Battery Charger & Power Bank

As someone who uses different battery sizes (18650, 20700, 21700), this charger is a godsend. The adjustable slots accommodate everything perfectly. The upgraded safety features give me peace of mind, especially when charging overnight.

I've been using this for a week straight and I'm impressed. The faster charging really makes a difference—my 21700 cells go from empty to full in no time. The fact that it doubles as a power bank is brilliant. No more carrying separate charger and power bank.

The smarter charging logic is a lifesaver. Single cell charges at 5V which is gentler on the battery, and when I put two cells in, it balances them before kicking into fast charge. This level of care for battery health is why I stick with XTAR.

I enjoyed my other one as much, I bought another one to use around the house and for my family to use.

I really like this powerbank and charger. I got tired of my normal powerbanks always losing cabacity and eventually swelling to be unsafe. With this one I can change the batteries out easily if they start to get too old. Also, I can carry extra batteries with if I need for extra capacity. I pair this with a 21700 battery flashlight, so I always have 3 21700 batteries with me at all time. I love the display. Only complaint is that whatever fast charger i use, I still seem to get only 1.6 amps per battery instead of the advertised 2 amps.

The XTAR PB2SL V2 offers many great features and allows the average 18650 or 21700 enthusiast to make better use of their batteries, or the average noob to easily make a powerbank with a custom capacity. One of my main issues with this powerbank is the output wattage. Even when paired with two 21700 25A discharge cells, the output wattage is simply disappointing compared to some of the readily available powerbanks at half the price of the kit. Now onto some of the good things. The magnetic lid makes swapping batteries simple, the dual port output allows me to charge two devices simultaneously, and the display shows me the current being drawn which is nice to have. Overall, the build quality of the device is quite good, but there is only a few use cases that would compel most to buy this product, like if you have extra cells laying around or travel and use rechargeable battery cells a lot. If that is you, then I would 100% recommend this product. This would allow you to maintain your cells and you might make more use of them.

The build quality is exceptional. Feels solid in hand, the USB-C port is well-placed, and the battery contacts are robust. I've dropped it once (accidentally) and it survived without a scratch. This thing is built to last.

The display is much more accurate than the V1. I can actually trust the percentage shown now. Build quality is solid, and the matte finish feels premium. Perfect for camping trips when I need to charge my headlamp and phone simultaneously.

Finally a charger that doesn't overcomplicate things. The smoother operation means I don't have to remember a specific order to plug things in. Just insert batteries or adapter in any order and it works. Simple, reliable, and well-built.

This is the perfect travel companion! I love that it supports both 18650 and 21700 batteries, so I can use my existing cells. The new startup sequence works in any order now—no more fiddling around trying to get it to boot. Highly recommended for anyone who needs reliable power on the go.

The low-current mode is a game changer for me. I use it to charge my wireless earbuds and smartwatch, and the double-click to enter/exit is so intuitive. The screen stays on so I can always see the battery status. This is my third XTAR product and definitely the best one yet.

I was worried about replacing batteries while the device was running, but the V2 supports hot-swapping safely. I've swapped cells multiple times during use without any issues. The charging logic is also smarter now—single cell charges at 5V, dual cells trigger fast charging after balancing. My batteries last longer.

I bought this for my photography gear. I'm out in the field for hours and need reliable battery charging. The PB2SL V2 delivers. The screen shows precise voltage and capacity, and the low-current mode is perfect for my smaller devices. Absolutely love it.

Upgraded from the V1 and the difference is night and day. Startup is seamless now, no more boot issues. The dual-cell fast charging after balancing is a huge improvement—my batteries are healthier and charge faster. Worth every penny.

This is my go-to charger for all my vape batteries. The low-current mode works flawlessly for smaller batteries, and the safety protections are top-notch. I've recommended it to all my friends who vape. Best purchase of the year.

Este cargador es increíble. La función de modo de baja corriente funciona perfectamente para mis auriculares y reloj inteligente. El hecho de que pueda cambiar las baterías mientras está en funcionamiento sin dañar el dispositivo es una gran ventaja. Lo recomiendo totalmente.

Dieser Ladegerät ist die beste Investition, die ich für meine Akkus getätigt habe. Die verbesserte Ladelogik schont die Batterien, der Bildschirm ist präzise und die Verarbeitung ist erstklassig. Besonders praktisch ist der Low-Current-Modus für Kopfhörer und Smartwatches. Absolut empfehlenswert.

I've been through countless chargers and this one finally ticks all the boxes. Fast charging, accurate display, hot-swap support, and low-current mode for small devices. It's the Swiss Army knife of battery chargers. Five stars all the way.

The upgraded display is so much clearer than the old version. I can read it even in bright sunlight. The operation is buttery smooth—no more guessing which order to plug things in. XTAR really listened to user feedback and delivered a winner.

La precisión de la pantalla mejoró mucho comparada con la versión anterior. Ahora puedo confiar en el porcentaje que muestra. El cargador es compacto, resistente y la carga rápida es realmente rápida. Ideal para viajes.

I love that I can see the battery status clearly on the screen while charging my devices. The screen stays on during low-current mode, which is super helpful. It's small enough to fit in my backpack pocket but powerful enough to charge my laptop via USB-C.

Perfect for outdoor adventures. I take it hiking and camping, and it never lets me down. Charges my phone, GPS, and headlamp without breaking a sweat. The fact that I can carry spare 21700 cells means I never run out of power.

Ce chargeur est un véritable bijou technologique. La gestion intelligente de la charge prolonge la durée de vie des batteries, et le mode basse courant est parfait pour les petits appareils. L'écran précis et la possibilité d'échanger les batteries à chaud en font un produit exceptionnel. Je suis ravi de mon achat.

Amazing I was using the previous model ,but with this adjustments In this model I can use more securely the 18650!!!!!!! Good job XTAR !!!!!!

Great charger/Powerbank ! Digital readout showing everything you need to know about the batteries/charge rate in amps and volts etc.- Percentage of charge left, and percentage to being fully recharged. Nice and compact, and you can 'Change the batteries' when they are depleted which is brilliant !! - I bought the 21700 batteries as well to go with it. (You have to purchase these separately), but they are good batteries! It can charge protected cell batteries which is great. Choice of colours which is nice too.
