Nice, I'll give it a shot. Since the pre-coupon price was >25, it gave me free same day shipping. I'll take it.

Hard pass. I will not buy any of these that don't have a USB-C charger anymore. REALLY tired of all these small barrell chargers of different sizes.

Great deal! I got mine for $10 and have been very happy with it! Bought a different brand before too and hated it! It was a piece of junk. But this Coslus is great! Pressure is good, holds charge for a long time.
Buying one now for my son.

I just got one very similar to this tonight. I had to check if it was the same. Funny, mine says I'll either get a type c or two prong lol. My last one was type c and I didn't even bother to look if it wasnt type c.
