We really love a good deal here on Android Police, but what we love more is a good freebie. Granted, in this case, you have to buy something and part with your hard-earned cash to get your gift, but you're still eventually getting a gadget for the awesome price of zero bucks. And it's even better when both items are best sellers and really well rated on Amazon. If you're interested, here are the deets.
The speaker in question is Omaker's M4. It's IP54 rated to be shockproof, dustproof, and splashproof. It has Bluetooth 4.0 and NFC to easily connect any Android phone (or other device) and start music playback. And it can play music for up to 12 hours on 80% volume, then when the battery dies, it charges over MicroUSB. It costs $34.99 on Amazon and comes in both orange or army green colors.
The desktop charger is Omaker's 5-port 40W 5V/8.5A. Like the name says, it has 5 ports, but they're smart: no port is labeled as 1A or 2.4A. All of them can output up to 2.4A depending on your device's hunger for juice, but when used concomitantly, they can total 8.5A. That's enough to fill 4 Android devices at near full power. The only drawback is that there's no Qualcomm QuickCharge port, but you can always use this in your travel bag for example. It usually costs $23.99 on Amazon.
If you add both items to your cart now, then apply the promo code OMAKERM4, you'll see the price of the charger deduced from your total, so that both units cost $34.99 together. Maybe you wouldn't buy any of these at their regular price, but with this deal, I gotta admit they're quite tempting.
