If you weren't swayed by Amazon's Bluetooth speakers Gold Box deal or if you're looking for a solution to charge all the new speakers that you just bought, you might be happy to know that the Yubi Power 30W wall charger is being discounted to $8.99 — a whopping 82% off its original MSRP of $49.99.

As with most wall chargers in this category, the Yubi offers several USB outputs with varying amperage. This particular model has 4 ports (nowhere near the 40 ports Yubi that Artem is drooling over, but you're not Artem so you should be happy with just 4, OK?), divided as 2 with a maximum output of 2.1A and the other 2 with 1.5A. If you use all 4 ports together, you should know that the unit can't output more than 6.2A — which is still enough to charge 2 phones and 2 tablets rather efficiently.

The Yubi comes with built-in flippable prongs so you don't have to worry about carrying a separate cable to plug it in, and can take input voltage anywhere from 100 to 240V, making it a decent travel companion. (You'll just have to worry about the wall outlet adapters then.)

We've previously featured many similar units from Anker and Poweradd, but this is the lowest price we've ever seen on a multi-port USB wall charger. The Amazon reviews (while only 14 at the moment) aren't too shabby either, with an average rating of 4.5 stars. To sweeten the deal, this unit will ship for free if you're a Prime member or if your order total is over $35.
