Universal Travel Dock Battery Charger For Logitech Harmony RIG7 720/785/88?0 one 1/885/890/89?5/900 pro

Works as planned. The pins are adjustable which I didn't notice. While this can be a bit of a pain to figure out where to place the pins at first, I can see how these movable pins could work on all sorts of flat rechargeable batteries.

Not a bad price for a pretty useful charger. This is my 3rd Chinese-manufactured charger for my Logitech Harmony One. Love the remote for years; the chargers ... not so much.The original charging cradle crapped out early, and are way too expensive for something that dies young, even if it leaves a pretty corpse.The cheaper chargers tend to fall apart after a few years, usually announced by a prong remaining in the wall outlet when the charger is pulled free.This charger seems to be better made, but, of course, only time will tell.

It works but because of the design, changing batteries is difficult. The contact pins are adjustable side to side (which is a good thing) but there is no way to lock them in place for any given battery configuration. Consequently, it is easy to misalign them when changing batteries. The contact pins are also somewhat fragile and, therefore, subject to bending. The design of the spring loaded slide, which holds the battery against the contact pins, makes loading of batteries unwieldy.I bought it to charge batteries for my universal TV remote thinking I would be charging one battery while using another. In practice, I found it so difficult to change batteries in the charger that I usually just place the remote in its own charging cradle.The charger comes with no instructions so I was concerned about having the right polarity when placing the battery in the charger. I finally found an online instructional video and learned that when the battery is positioned correctly a blue light on the face of the charger comes on and that having the wrong polarity would not damage anything.The charger has fold-out prongs on the back that fit a standard US 110V outlet. It would be more convenient for me if it were on a cord and could be placed on a desktop rather than having to plug it into a wall outlet. For my use, the ideal design would be a simple desktop cradle, similar to an iPhone cradle, into which the battery could be placed.

Given the price, it does charge my Harmony One remote battery. It's cheap and feels like it, but works as advertised. Saved me a lot of money over buying a new dock.

Charges my replacement battery for my Harmony One remote.

I originally posted that this product didn't work but I finally figured it out and it works great. There are no directions and key is getting the pins on the correct contacts.

Came with no instructions, but you do not have to be a tech wizard to figure this little unit out.

A little delicate but works perfectly. Highly adaptable and forgiving of any polarity confusion.
