26800 blue light blinking while charging other device?

hey guys. i have the 26800 battery with the 4 led lights.
im now emptying it and then ill fully charge it.
from the box it had about 50%. (2 lights)
after 10 mins one light went off, so i assumed it actually had about 25% of the box.
it charged my phone nicely and the blue led was solid blue.
few minutes ago it started to blink blue.
what does that mean? (its still charging my phone, but it blinks)
.
*if it means its low on battery its a shame, cuz it charged only about 2 hours-few phones- each of them had 60%+ battery (so it charged about only 2,500mha worth of battery…:anguished:
is possible its already low on battery?!?!?

Hi @saar_nisani , what phone(s) are we talking about so we can get an idea of battery sizes the PC is recharging? In regards to your observations…

Not necessarily, it may have just dropped below the threshold to keep the light activated, such as 35-45%…

As above, that is has fallen below the set threshold to keep the LED solid and as a warning to the user that the battery is getting to the stage of requiring a recharge…

Have you tried giving the unit a full charge and then comparing the discharge times? Using a partial out of the box charge to judge the overall charging times would not give an accurate representation…
