A USB charger that is smaller & cheaper than Cottonpickers

Has anyone seen those yet?

They look really great (and price – $11 – is very good too), and leads are also detachable (so you can have few sets of wires – wired to a battery holder, wired to magnets, etc).
The only disadvantages I see is that you have to make your own leads, and that 100/500mA switch requires soldering, but otherwise it’s a pretty little charger!

Here are a couple photos:

This is a good find, thanks for sharing.

Do you have any experience with the sales portal? (Tindie)

Nope, not yet.
I’ve placed an order on this charger, though, and I’ll let you know how it goes – but I can’t you update you on how it goes until I receive it, which won’t be earlier than 25th January, when I’ll return from my 2-week long skiing trip to Switzerland.

They seem to have various unique and interesting electronic kits, though.. For example, who knew there was such thing as lightning detector, which could detect a lightning 40 km away?!

It’s not preorder, I got mine already.

Looks big?

I bet it doesn’t now. Silly

Mine terminates at 4.19V.

Can’t comment any further as I haven’t used it much yet, but I have nothing to complain about.

That's what I said, but the checkout process indicates that it is.  I got mine a few days ago, but I haven't even opened the package yet.

The low mode should be lower.

It didn't come with leads.  It has a JST connector.  Aside from male/female, are all JST connectors the same?

The low mode should be lower.

They should be.
At least all ones I have fit it nicely.

Saw this a while back, could well come in handy Smile

Just so you know, “jst” is loosely used to describe connectors of various styles unfortunately.

Even among “mini jst” types there are many.

The example above is for 3-pin servo connectors but the categories are the same for 2-pin. Thanks to sparkfun and the like, I believe jst-xh (2.5mm) has become common for charger types these days. Just confirm it with someone.

islisis, I'll look into that.

 

These ones don't fit.

Okay, so I ordered this lead with connector.  It has macro pictures of the connector, and it looks right.  I got my fingers crossed.

https://www.sparkfun.com/products/9914

The connector from Sparkfun fits.  I think this charger should come with leads even if it increases the price slightly, especially since the seller/inventor cannot specify the connector.

 

 

@Changchungleds, I don't think that will work.  That connector looks like it has two ribs on top, but the right connector only has one rib.

The low mode should be lower.
