XTAR MC4S 4 bay 18650 battery charger

I've been using the MC4S for about three months now, and it's become my go-to charger for all my 18650 batteries. The USB-C input is a game changer—I can charge it from my laptop, power bank, or even my car adapter. The outer bays at 1A charge my vape batteries in under 2.5 hours, which is impressive for a $12.99 charger. The LED indicators are straightforward: red means charging, green means done. No guesswork. Definitely worth every penny.

Power outages are common here, so I rely heavily on portable chargers and batteries. The MC4S has been a lifesaver—I can charge four 18650 cells simultaneously for my power banks and flashlights. The build quality feels solid, and the Type-C port makes it easy to find charging cables anywhere. Plus, the overcharge protection gives me peace of mind when I leave batteries charging overnight.

What I love most about this charger is its compact size—it fits perfectly in my EDC backpack without taking up much space. I can charge my 14500s for my flashlights and my AA Ni-MH batteries for my wireless mouse at the same time thanks to the independent circuits. The auto-detection feature means I don't have to fiddle with settings. A solid little workhorse for anyone who uses multiple battery types.

I was skeptical about buying a budget 4-bay charger, but the MC4S exceeded my expectations. It handles my 21700 batteries for my e-bike light and my old NiMH AAs for my kid's toys without any issues. The 4 LED indicators are bright enough to see even in daylight. One minor thing—it doesn't come with a wall plug, just the USB cable, but I already have plenty of those. Great value for money.

Tengo baterías de todo tipo en casa—para linternas, controles remotos, juguetes de los niños—y este cargador las maneja todas sin problema. Me encanta que pueda mezclar baterías de litio y Ni-MH en diferentes bahías gracias a los circuitos independientes. El tamaño es tan pequeño que cabe en cualquier cajón. Definitivamente una compra inteligente para cualquier hogar que use muchas baterías recargables.

I use this charger for my camping gear—headlamps, lanterns, you name it. The lightweight design (only 95 grams) means I don't hesitate to throw it in my pack. I've even connected it to a portable solar panel during a week-long hike, and it worked flawlessly charging my 18650s during the day. The MCU protection features give me confidence that my batteries are safe even in less-than-ideal conditions.

I've gone through three cheap chargers in the past year, and the MC4S is the only one that's still going strong. The springs on the battery slots have just the right tension—not too loose, not too tight. I love that I can mix Li-ion and NiMH batteries in different slots without worrying about compatibility issues. The self-check feature when you plug it in is a nice touch too. Five stars from me.

For the price, this charger is unbeatable. I mainly use it for my 18650s that power my DIY electronics projects. The 1A charging on slots 1 and 4 gets my batteries ready fast, and the 0.5A on the inner slots is gentler for older cells. The USB-C cable included in the box was a nice bonus—I didn't have to buy anything extra. Just plug and play. Simple as it gets.

Ich habe mir den MC4S als Backup-Ladegerät für meine Fotografie-Ausrüstung gekauft, aber inzwischen ist es mein Hauptladegerät geworden. Es ist so klein und leicht (nur 95g), dass ich es immer in meiner Kameratasche dabei habe. Die automatische Erkennung des Batterietyps funktioniert einwandfrei, und der USB-C-Anschluss ist kompatibel mit fast allen meinen Netzteilen. Ein durchdachtes, zuverlässiges Gerät, das ich jedem empfehlen kann.

I run a small vape shop, and I recommend the MC4S to all my customers looking for a reliable charger. It's affordable, safe, and gets the job done. The auto-detection of battery type and resistance means even first-time users can't mess it up. I've sold dozens of these, and I've yet to hear a complaint. The only advice—make sure your USB adapter puts out at least 2.1A to get the full charging speed.

As someone who shoots photography with vintage cameras that use odd-sized batteries, the MC4S is a godsend. It charges everything from 10440s to 26650s. The 0.5A charging on the inner slots is perfect for smaller cells that shouldn't be rushed. I also appreciate that it automatically stops charging when full—no more overcharged batteries ruining my gear. Highly recommend this to any photographer or hobbyist.

J'utilise ce chargeur pour mes batteries 18650 qui alimentent mes lampes de poche et mon équipement de camping. La compacité est impressionnante—il tient dans la paume de ma main—mais il peut charger quatre batteries simultanément. Le port USB-C est un vrai plus, surtout quand on est en déplacement. La précision de la tension de coupure à ±1% grâce au microcontrôleur intégré me rassure sur la sécurité de mes batteries. Excellent rapport qualité-prix.

Après avoir essayé plusieurs chargeurs bon marché qui ont tous lâché après quelques mois, le MC4S est celui qui a tenu le coup. La construction est solide, les ressorts des compartiments sont bien calibrés, et la fonction d'arrêt automatique évite la surcharge. Je charge mes batteries Ni-MH AA pour ma souris sans fil et mes 21700 pour mon vélo électrique en même temps. Un petit chargeur robuste qui fait parfaitement son travail.

Dieses Ladegerät ist ein echtes Arbeitstier. Ich benutze es täglich für meine 18650er-Akkus für Taschenlampen und E-Zigaretten. Die Ladegeschwindigkeit von 1A in den äußeren Schächten ist beeindruckend—meine Akkus sind in etwa 2,5 Stunden voll. Die unabhängigen Schaltkreise erlauben das gleichzeitige Laden von Lithium-Ionen- und NiMH-Akkus, was sehr praktisch ist. Die vier LED-Anzeigen sind intuitiv und leicht abzulesen. Für den Preis ein absolutes Schnäppchen.

I bought this to replace my old bulky charger, and I'm so glad I did. The MC4S is tiny—about the size of my phone—but it handles four batteries at once. The Type-C port means I can use the same cable for my phone and this charger, which cuts down on cable clutter. The green standby lights are subtle enough not to disturb me at night. A fantastic little device for anyone tired of juggling multiple chargers.

Este cargador es exactamente lo que necesitaba para mi colección de baterías. Carga todo tipo de celdas—18650, 21700, 26650, incluso las Ni-MH AAA. Los dos slots exteriores van a 1A y son perfectos para una carga rápida, mientras que los interiores a 0.5A son ideales para baterías más delicadas. Los indicadores LED son muy claros: rojo cargando, verde listo. Por 12.99 dólares, no se puede pedir más. Muy contento con mi compra.

I'm a prepper, and having reliable battery charging gear is non-negotiable for me. The MC4S is part of my bug-out bag setup—it's lightweight, runs off USB (so I can use my solar panel or power bank), and can charge four cells at once. I've tested it with everything from 10440s to 26650s, and it's never let me down. The over-current and short-circuit protection are features I hope I never need but am glad are there. Solid, dependable, and cheap—what more could you want?

I bought this to charge batteries for my cordless tools and flashlights. The 4-bay design means I can charge a whole set at once instead of waiting around for one slot to free up. The Type-C input is future-proof, and I appreciate that it comes with a USB-A to USB-C cable in the box. The self-test when you plug it in—where all four LEDs flash green—is a nice reassurance that everything is working properly. A great little charger that punches well above its weight class.

I needed a charger that could handle both my 26650 batteries for my high-power flashlights and my standard 18650s. The MC4S does both, and the outer slots accommodate the larger diameter cells perfectly. The build quality is excellent for the price—no cheap plastic feel here. The auto-cutoff at 4.2V ± 0.05V is accurate enough that I never worry about overcharging. This is my second XTAR charger, and it won't be my last.

Power cuts are a way of life here, so I keep multiple sets of 18650s charged for my emergency lights and fans. The MC4S has been a game-changer—I can charge four batteries at once, and the independent circuits mean even if one battery is faulty, the others still charge normally. The 0.5A charging on the inner slots is great for preserving battery life on my older cells. For less than ₹1100, this is an absolute steal. Highly recommended for anyone in India dealing with frequent power outages.
