It's not hard to find USB car chargers, nor is it difficult to find ones with multiple ports. It's not challenging to find them cheap, either. So to catch our eye, you're going to need a lot of ports at a low price.
Well lookie here. Omaker is offering a 3-port 26W car charger with a max output of DC 5V 5.1A, and Amazon shows it priced at $9 (marked down from a humorous price of $50). Not only that, you can get it for $2 less if you use the coupon code OMAKER11 at checkout.
If you want the white model, that one requires coupon code OMAKER22. Either way, you're looking at a $7 product that has over 500 ratings and a nearly five-star average. There are worst ways to part with seven bucks.
This deal is back, only now you can get the chargers for just $5. For the white model, enter 9ZSK7HVI at checkout to subtract $4 from the regular price. For black, you want SR3WKS5O.
