Best Portable Car Battery Charger Under 50

[5 x 2.8 x 1.5"] Originally bought my Watson portable car charger for my Nikon D5300 battery. Didn't realize that the plates were interchangeable, so when I upgraded to my new D810, I figured I would need to buy a whole new charger. But no...just a new adapter plate and I was all set. Great product!

[Gray] Lasts forever. Best value yet. The only thing is that the charger only charges one battery at a time.

[400 W ] Best small portable speaker, battery, sound, fabric and look!

[External PSU] THIS IS A GREAT BUY!!!!BEST MIC YOU CAN GET FOR UNDER 500!!!...WILL BE BUYING FROM THEM AGAIN VERY SOON!!@@!!!! JW

[LED] Great charger. It can be used in an outlet or the car with the included adapter.� Small size makes it portable.� Charges quickly. Just what I wanted in order to always have a backup battery for my Nikon P900.

[1.4 lb] This is a fantastic charger, works well and shows you exactly how charged each battery is. I love that it comes with a car charger as well

[LED] This charger can be used for car or home and allows me to charge my camera battery out of the camera or keep my backup battery ready to go.

[29 lb] Best portable screen.

[0.04 lb] I had lost my charger for my pentax battery, replacement was over 50 bucks.. this has a multitude of functions and was less than half the cost.

[Download] The Goal Zero Nomad 20 is a great portable solar panel. I haven't given it a lot of use yet, but already it works as intended. I am able to charge my phone off it when the sky is overcast. In direct sunlight, it charges faster. I was also able to charge a usb battery pack, that doubles as a car jump starter, while out camping where there was no electricity. This was handy, considering I drained my car battery running a waffle maker. Downsides? it doesn't come with a carrying strap, though it isn't hard to add one.
