The TrendOn are trickle charge. My G5 charges in 30-45min, i.e. "quick charge".
There's threads on this sub discussing batteries; many oem not performing well BUT the consensus on the battery kits (5100) was they seemed legit, or at least performed as well. Batteries or chargers separate was luck. So I just got the kit. Worked for me. I don't have any magical insight. The prices vary. Just recently I saw kits at $25. There for awhile some about $37 and now it looks like they are $49 again. I missed out the 1st time I saw the lower price and had to wait a couple of months for the price to drop again. But it happens.

I went through several LG cords before trying a Samsung one which has lasted the longest for quick charging. LG's cables didn't last for me. I'm addicted to the quick charge because from day 1, the battery only lasted about 4 hours for me. That's fine if I can charge again in 30 min. Even better with a spare that charges fast. The TrendOn took all night = useless for me. Everyone uses their phone differently I guess. I can charge LG in my car. I couldn't with TrendOn. I should probably sell you my old TrendOn's.
