It is using 26650 lithium battery cells that can hold up to 1000 times charge and discharge cycle. By the way, the test was done with average room sound level. Shorter if you play louder. And it took around 7 hours and a half to fully charge.

Input buttons & clip hook

Arma K1 sound quality is good. The treble is clear and bass is there. And it can really produces loud sound and no distortion even at maximum volume level. You can call for a mini party with it easily. However, there is one minor issue. The bass is gone when you opened up the back cover to charge tablet or smartphone. Not a big deal just you can’t enjoy wonderful music anymore while charging.

Yup, it can fully charge most of the smartphones in the market easily.

Lastly, its LED flashlight is super bright too. Easily light up whole pitch dark room. And the throwing distance is quite far too. It will definitely enough to light up your whole outdoor adventure trip with its long lasting battery. And there are 3 modes to select – bright, average and SOS. Okay, here is the bonus.
