I have the ikea VINNINGE charger. It's great.
I use it as my daily charger for some really small audio players that use aaa, and rotating between the empty battery in my player and the charger and I've never had a problem.
My mp3 player uses 1 aaa, my headlamp uses 2 aaa and my one travel beard trimmer uses 1 aa battery. The only upgrade is that I've glued a ribbon of fabric to the back and use it to pull the aa batteries out of it which is a bit of a pain.
I had a lacrosse bc-900 that went bad and I thought that I'd have issues with the VINNINGE's lack of information, but like their batteries, this charger is so cheap that I don't care.
The usb is seriously great. It's chained with the rest of my USB devices that require usb power on my DIY usb harness, so I can charge it, along with the 6 other usb devices that need power all occupying just one outlet.
And since my charging station is next to my workspace, it's now much easier to access and change batteries.
What kind of devices do you need to power? How many batteries do you require?
The worst instance usually requires me to pilfer remotes for those batteries, but other than that, I've never run out of power.
If you're trying to power a flash head for a camera, no it won't have enough power for all those batteries, but if you're travelling and have the discipline to change and rotate batteries, I highly recommend it.
Coupled with a 4000mah powerbank, you can easily be charging while on the go, and that's a huuuge plus.
And it's much smaller than the litokala, which is super important in my books.
I don't charge 18650 cells, and after 15 years of monitoring charge capacitys with a la bc-900, I realize that I'm much happier not knowing every little intricacy of every cell I own.
