XTAR SC2 QC3.0 3A Type-C Fast Charger for 18650/20700/21700/26650 Batteries

I bought the SC2 for our campervan and also use it at home in Melbourne. It's perfect for charging our 18650 batteries for headlamps and a portable fan. The compact size means it fits in the glovebox when we're traveling. The USB-C port is great because we can power it from our van's USB outlet or a power bank when we're off-grid. The QC3.0 fast charging is much quicker than our old charger. The three-stage charging and safety features give us confidence. It's been a reliable little companion on all our trips.

I cycle everywhere in Amsterdam, so my bike lights are essential. The SC2 lives on my hallway shelf next to my keys. It's small enough to be unobtrusive but powerful enough to fully charge my 18650s in about an hour with a QC3.0 adapter. The three-stage charging (TC-CC-CV) gives me peace of mind that I'm not damaging my batteries. I also appreciate the reverse polarity protection — I once put a battery in the wrong way and nothing bad happened. Great little charger for everyday use.

I bought the SC2 for my home office in Osaka. I use it to charge 18650 batteries for my desk gadgets and a couple of 21700s for a high-powered flashlight I keep for emergencies. The fast charging is excellent — with a QC3.0 adapter, a single 21700 charges at 3A. The compact design means it sits neatly on my desk without cluttering. The build quality is impressive for the price. The LED indicators are clear and easy to understand. I've recommended it to several colleagues already.

Ich nutze den XTAR SC2 jetzt seit etwa drei Monaten täglich für meine E-Zigaretten-Akkus. Was mich am meisten überzeugt hat, ist die 0V-Aktivierungsfunktion — ich hatte zwei 18650er, die ich versehentlich tiefentladen hatte, und der SC2 hat beide wiederbelebt. Das kompakte Design passt problemlos in meine Schreibtischschublade, und das Drei-Stufen-Ladeverfahren TC/CC/CV gibt mir ein sicheres Gefühl. Mit einem QC3.0-Netzteil lädt eine einzelne Zelle mit 3A, das ist beeindruckend schnell für so ein kleines Gerät. Klare Kaufempfehlung für Dampfer!

I bought the SC2 specifically for my collection of 21700 batteries used in high-power flashlights. The compatibility with protected 21700 cells is excellent — many chargers struggle with the extra length, but the SC2 handles them without issues. I use it in my home office where I also do flashlight reviews as a hobby. The QC3.0 fast charging at 3A for a single cell is impressive. I tested it with a USB power meter and the charging curve is well-managed. The compact design means it doesn't take up much desk space.

I've been using the SC2 in my small Tokyo apartment for about four months now. Space is limited here, so the compact size is perfect — it fits neatly on my bedside table. I mainly charge 18650 batteries for my bike light and headlamp. The fast charging with QC3.0 is great when I forget to charge until the night before a ride. The soft start feature and three-stage charging give me confidence that my batteries will last longer. The LED indicators are subtle enough that they don't bother me when I'm trying to sleep.

J'utilise le XTAR SC2 depuis six mois pour recharger les batteries de mes lampes de poche de randonnée. Ce qui m'impressionne le plus, c'est la compatibilité — il accepte les 18650, 20700 protégées, 21700 et même les grosses 26650. Avec un chargeur QC3.0, une seule batterie se recharge à 3A, ce qui est vraiment rapide. Le port USB-C est un gros plus par rapport à mon ancien chargeur micro-USB. Je l'emmène même en camping avec une batterie externe. Petit, léger et efficace — exactement ce que je cherchais.

As someone who works night shifts at a warehouse, having reliable charged batteries for my high-lumen flashlight is non-negotiable. The SC2 has become my go-to charger at home. I keep it on my kitchen counter next to my coffee maker. The QC3.0 fast charging means I can top up my 21700 batteries during my morning routine before heading to bed. The 0V activation saved two batteries I thought were completely dead. The build quality feels solid and the Type-C port is convenient since all my devices use the same cable now.

Living in a small HDB flat in Singapore, I need charging solutions that don't take up much space. The SC2 is perfect — it's about the size of a deck of cards. I use it for my vape batteries and a couple of 18650s for my bicycle lights. The QC3.0 fast charging is a lifesaver when I'm rushing out the door. The USB-C port means I can power it from my laptop or a power bank. I've had it for about five months now and it's been completely reliable. The LED indicators are bright enough to see in daylight too.

I bought this SC2 charger primarily for my collection of 21700 batteries that I use in my Sofirn flashlights. The QC3.0 support with my Anker wall adapter really makes a difference — a single 21700 goes from nearly empty to full in under two hours, which is a huge improvement over my old Nitecore i4. The LED indicators are simple but effective, and I appreciate that protected 21700 cells fit without any struggle. The USB-C port also means I can power it from my laptop when I'm traveling for work. Solid little charger for the price.

After my old Nitecore finally gave up, I decided to try the XTAR SC2 based on the positive reviews. I'm glad I did. I use it in my home workshop for charging batteries for my RC car and a few flashlights. The fast charging at 3A for a single slot is noticeably quicker than my old charger. The build quality feels solid — it has some weight to it despite being compact. The LED indicators are simple but effective. I've been using it daily for about two months now with zero issues. Great value for the price.

I picked up the SC2 after my old charger finally died after five years of service. I use it mainly for 18650 batteries in my garden lights and a few 21700s for a powerful torch I take camping. What I really like is the intelligent adapting identification — it automatically picks the right charging current. The QC3.0 protocol means it charges noticeably faster than my old micro-USB charger. It sits on my garage workbench and has survived a few accidental drops onto the concrete floor without any issues. Good value.

Compré el XTAR SC2 para mi taller de electrónica y ha superado mis expectativas. La función de activación 0V es increíblemente útil cuando recibo baterías que los clientes creen que están muertas. Con un adaptador QC3.0, puedo cargar una 21700 a 3A mientras simultáneamente cargo otra a 2A. Las luces LED son fáciles de leer incluso con mis gafas de cerca. Lo tengo en mi banco de trabajo junto a mi estación de soldadura. La construcción es sólida y el precio es muy razonable para lo que ofrece.

I use the SC2 at home in Moscow for charging batteries for my flashlights and a portable radio. The compact size is perfect for our apartment where space is limited. The QC3.0 fast charging works great with my USB adapter — one 18650 charges in about an hour. I especially like the 0V activation feature because Russian winters can be harsh on batteries. The three-stage charging process gives me confidence that my batteries will last. The LED indicators are clear and the charger feels well-made. Very satisfied.

I bought the SC2 for my husband who uses 18650 batteries for his vape mods. The fast charging with QC3.0 is a game-changer — he used to wait hours for his batteries to charge with the old charger. Now with two slots at 2A each, he always has batteries ready. The compact design fits perfectly on our bedside table. I also appreciate the safety features — overcharge protection and reverse polarity protection give me peace of mind. The Type-C port is convenient since our phones use the same cable.

I was skeptical about buying yet another charger, but the SC2 genuinely impressed me. I use it in my art studio to charge batteries for my portable photography lights. The compact size means it doesn't clutter my already messy desk. With a QC3.0 adapter, I can charge one 26650 at 3A — perfect for when I have a photoshoot the next morning and forgot to charge the night before. The LED indicators are clear and the build feels premium despite the low price. The 0V activation is a nice safety net too.

As a volunteer member of our local search and rescue team, I depend on reliable equipment. The SC2 is now my primary charger at home for all my 18650 and 21700 batteries. In Sweden's winter, batteries drain fast in the cold, so having a fast charger with QC3.0 support is crucial. I keep it in my utility room on a shelf next to my gear bag. The three-stage charging is gentle on the batteries, and the 0V activation has revived cells that were deeply discharged from cold weather use. Highly recommended for anyone who depends on their gear.

I keep the SC2 on my bedside table for charging my vape batteries overnight. It's so compact that it barely takes up any space. I love that it has a Type-C port because I can use the same cable as my phone. The LED indicators are a bit bright for bedside use, but I just put a small cloth over them. The QC3.0 fast charging means my batteries are always ready. The 0V activation feature is great — I've revived a couple of batteries I thought were dead. Great little charger.

I ordered the SC2 to charge batteries for my drone controller and a few 18650 flashlights. Living in São Paulo, power outages are not uncommon, so having a reliable charger that works with a power bank is essential. The QC3.0 fast charging is great — I can charge two 18650s at 2A each simultaneously. The build quality feels solid and the LED indicators are easy to read. I've been using it daily for about three months and it's been completely dependable. The price is very reasonable too.

I use the SC2 in my home in Dubai to charge batteries for my security camera system and a few flashlights. The compact size is great for our apartment, and the USB-C port means I can plug it into a wall adapter or even my car's USB port. The fast charging with QC3.0 is perfect for our busy lifestyle. What I really appreciate is the 0V activation function — the summer heat here can drain batteries quickly, and it's saved several cells that I thought were beyond saving. Build quality is excellent.
