BL

A brand name appearing on various Chinese handhelds. First appeared (I think) as simply part of the model number designation of otherwise unbranded consoles - eg BL-xxx - but there's now also trademarked logo (seen, for example, on the packaging of the BL-826A), so I'd say I can consider it a "brand" now.

For a long time, I couldn't find the company associated with this brand. Eventually, it was discovered to belong to Shenzhen Xinbaolong Electronics Factory, an affiliate company or spinoff of Macro Winners.

Wellminds have also been involved with the development and sale of some BL-branded consoles.

Some 1688.com listings have it standing for "宝龙" or "Baolong".
