I just noticed this travel style charger at Wallbuys for $1.70. I don’t think I’ve seen any charger for that price. It’s low enough to be an add-on buy when you order anything else.
I know it’s single channel, charge in parallel. Has anyone used these before?
Edit: The price has returned to a more typical $3.79. I forgot to update this post. Better than many resellers, but not as good as it was.
I have one. I got it in a bundle with a cheapo Ultrafire 502b and some surprisingly honest 2400mah UF unprotected cells. The first day I used it, it gave off a smell that I can only describe as “that smell made by cheap electronics”. I figured it would fail spectacularly within the first week, but a year later and with several dozen charges under its belt, it’s still going strong. Terminates every time at 4.15v too, which is nice if you care about the longevity of your cells.
Just get a bunch of these, when one burns up just let it melt and use another. Just put an outlet in the middle of a field somewhere and charge away. Just think, charge 20 cells at once for $17. Plug them all into a multi-plug outlet Lampoons Christmas Vacation style!
+1. Considering that you can pick up a reasonable charger for less than the cost of a protected panny nowadays, there’s no reason why you should take a gamble with this.
That’s the best use of these cheap chargers - I’ve done the same thing. The only thing is, it’s a good idea to plug in to the charger BEFORE inserting the cells - otherwise you might get a surprise. I could put a fuse in to mitigate this, but I’ve had no brain-fades so far! :bigsmile:
When I order from Wallbuys again, I’m adding a few for this purpose. I’ll put banana posts on it instead of the dangling leads. I’d forget and put the cells in first and melt the springs or something worse.
Sorry, might have helped slightly if I didn’t flip the 56. :zipper_mouth_face: ebay li-ion Charger Board or TP4056
Many don’t mention its tp4056 but you can read the chip on it. There are 4 or 5 different board designs all using tp4056, one even allows use of the safety function of monitoring battery temp.
They can be modified for different charging currents as well.
Neo magnets work for connecting different size batteries or add some battery holders.
Cover the board with a few layers of clear packing tape or heat shrink, really don’t want shorts.
