amiciSmart Smart Battery Charger, Single-Slot with LED Indicator

Good charger, charges 4200mAh battery in 5 hours with 5v charger which is recommended. Amicismart is the reseller of Yonii c1 charger in India. Once the charger is charging it shows red light, turns green after charging the battery to full. Do not leave the battery in the charger for long time, remove the battery once it's charged. I have fastened the battery using a rubber band with the charger to prevent it from jumping out because of the spring's tension. There's is an option to buy the torchlight and charger with two 18650 batteries as a combo pack in the amicivision torchlight page. The cost of 4200mAh battery is around 140rs in nearby electronics store, so far so good. This is a Good buy

Good Product.

I bought this to charge my flashlight battery in hopes of not spending too much money and getting a decent product. This product fulfilled my needs, however, what exceeded my expectation was the company's warranty (which needs to be registered online) and the dedication they show to call you to provide assurance that the product's warranty is active and they are available anytime to help with any queries related to the product. I am not sure how big of a company Amickart is, but their quality standards and customer dedication WOW'd me for sure! This is exactly how companies should be in terms of customer satisfaction.

Excellent product

It is not supporting the battery and unable to charge, so pls return the product.Product is good if it support it is neither supporting nor charging. Kindly return the item.

Not satisfied

It's a basic battery charger. The build quality is fair, the wires a little thinner than expected. The claim that it has charging indicator is a little false. It's very crude and one cant really make out if it's done 1 bar or 2 bar. Overall it does its job, but nothing fancy about it. Same as all other seen online.

At ₹600, this charger offers excellent value. It’s compact (8-9 cm long and 2-3 cm wide), lightweight (just 24 grams), and compatible with all cylindrical Li-ion cells, including 21700. Unlike many other chargers in this price range that plug directly into AC mains and does not heat up, this one uses a safer Type-C DC input. It also has a handy LED indicator—red for charging and green when the cell is full. Performance: The charger delivers 600mA until the cell reaches 3.8V, then gradually reduces the current, which is a safe and proper way to charge Li-ion cells. It takes about 4-5 hours to fully charge a 2000mAh 18650 cell. However, after the green light (at 4.13-4.14V), it doesn’t completely stop charging and continues at 60mA. To avoid overcharging, it’s best to unplug the cell once the green light comes on. Pros: Compact and lightweight Safer than most alternatives in this price range Works with all cylindrical Li-ion cells Includes a 1-year warranty Cons: Needs manual disconnection after the green light to prevent overcharging Note: This product is sold by Amicismart, an authorized reseller of the Yonii C1 charger. It has three small holes near the LED, but these aren’t an indicator bar—just a single LED inside. Conclusion: This charger stands out as one of the safest and most portable options for Li-ion cells at this price point. Just keep an eye on it and disconnect it when the green light appears to ensure the best performance.
