- Ultra-compact and lightweight (25g) โ ideal for travel or EDC
- No complicated settings โ plug in and charge
Design & Build Quality
The XTAR MC1 Plus is remarkably small โ about the size of a large USB flash drive. Its minimalist design features a single charging bay, a micro-USB input port, and one LED indicator. The plastic housing feels solid, not cheap or flimsy, with smooth edges that won’t snag in a pocket or bag.
The charging bay uses spring-loaded contacts that accommodate batteries from the tiny 10440 up to the large 26650. Insertion is straightforward: slide the battery in with the positive terminal facing the spring end. The spring tension is firm enough to hold batteries securely but not so stiff that insertion is difficult.
One design note: the micro-USB input (rather than USB-C) feels slightly dated in 2026, but it remains widely compatible with existing cables and adapters. For most users, this won’t be a dealbreaker.
Battery Compatibility
The MC1 Plus supports a wide range of 3.6V/3.7V lithium-ion chemistries:
Important: The MC1 Plus is designed only for 3.6V/3.7V lithium-ion batteries. It will not charge NiMH AA/AAA batteries or newer 1.5V constant-voltage lithium AA/AAA cells. Always verify your battery type before charging. Learn more about lithium vs NiMH batteries in our comparison guide.
Charging Performance
We tested the MC1 Plus with three common battery sizes under typical Kenyan power conditions (240V AC via USB wall adapter):
Charging speeds are respectable for a single-bay USB charger. The MC1 Plus auto-selects between 500mA and 1A charging currents based on battery size โ smaller cells charge at 500mA for safety, while larger cells like 18650 and 21700 can use the full 1A when powered by a sufficient USB source.
The LED indicator is simple but effective: solid red while charging, solid green when complete. There’s no blinking pattern for errors โ if something goes wrong (e.g., reverse polarity), the LED simply stays off and charging won’t start.
Safety & Protections
XTAR includes multiple safety circuits in the MC1 Plus:
- Overcharge protection: Stops charging when battery reaches 4.2V
- Short circuit protection: Cuts power if output is shorted
- Reverse polarity protection: Prevents damage if battery is inserted backwards
- Over-temperature monitoring: Reduces current if charger gets too warm
In our testing, the charger remained cool to the touch even during extended charging sessions. The auto-shutoff at full charge worked reliably โ we left a battery charging overnight and confirmed it stopped drawing current once complete.
