Unboxing
The XTAR SC1 PLUS slides out from its packaging which reveals the following:
- SC1 PLUS Charger / Power Bank
- Silicon strap
- USB-A to USB-C cable
XSTAR kindly sent a wall-charger for charging as well for testing purposes.
Build quality
The plastic used on the XTAR SC1 PLUS feels pretty good. The spring enclosure where the battery is meant to be held has good tension and slides smoothly. XTAR SC1 PLUS can fit up to a 26800 battery. I like how there is a silicon strap to hold the battery in place.
The size of the XTAR SC1 PLUS is just right. At a height of 12.5cm and thickness of 3.5cm, it is very portable and should slip in easily in any bag compartment.
Usage
Operating the XTAR SC1 PLUS is very straightforward. As long as you have the compatible battery installed, it is a simple plug-and-play. According the XTAR, the SC1 PLUS is compatible with the following batteries:
| Type | Size |
|---|---|
| 3.6V/3.7V Li-ion | 18650 / 18700 / 20700 / 21700 / 22650 / 25500 / 26650 / 26800 |
| 1.2V Ni-MH | D |
Once the battery is inserted, you can either choose to charge it or output power from it. XTAR SC1 PLUS is charged via the USB-C input, which cna be as fast as 15W fast charging as long as you have the right power adapter. While charging, you can monitor the four blue LEDs to track its progress.
To use it as a power bank, you have to use the USB-A port which offers up to 10W of charging speeds. Battery does feel warm while in use, but does not feel too got to be alarmed. Besides, XTAR SC1 PLUS is designed with anti-short circuit to prevent overload for safety.
Conclusion
I see the XTAR SC1 PLUS as a great companion for individuals who often goes on hikes and wants a power bank that is small enough to carry around. Being battery operated allows the battery to be used in other outdoor devices such as torchlights. And at just US$8.90, it is a really a low risk purchase.
