Pocket knifes and USB chargers, those are two things I can never own enough of. I like to have both scattered around my house ready for use whenever the need arises. If you feel the same way about USB chargers, then take a look at this deal, I think I found another charger worth owning.

GeekBuying on Amazon has discounted the Tronsmart 42W three port USB charger to $13 today, down from $19. It's a pretty sweet little charger that would be great for traveling. Up front are two standard USB ports, and one that is a Qualcomm Certified Quick Charge 2.0 port. In the rear the power prongs fold into the body for easy storage in your backpack or suitcase. Included with the charger is a six foot MicroUSB cable that supports the higher amperage of the Quick Charge port.

It wasn't long ago that this would have been a great deal for a single port Quick Charge 2.0 charger, so with two extra 2.4A ports this is a very solid buy.

There are few reviews on the device, but those that are there are positive. I wouldn't be too concerned, I purchased a Tronsmart charger last week and I have been impressed with the quality thus far. The manufacturer also provides an 18 month warranty, which should alleviate any concerns.

If you want to pick one up for yourself just head on over to Amazon and apply the coupon code KXL9IAZA at checkout to activate the discount. Let me know what you think of the deal in the comments below.
