Nop! you won't be able to charge them via USB, because the charger it self does not have USB port.

If they work fine in a drill or impact then maybe it is your saw. If they will not charge at all I have heard stories of other people having trouble with the chips in the battery going bad on Makita brand batteries. I think that is why i've seen people recommend that you fully discharge the battery befor charging it. I'm not an expert, but if that happened I don't know if their is any way to fix it. Check your lights on the charger and see if there's a error light. Maybe get a hold of the manufacturer. Good Luck!

Get a Nitecore charger. Don't bother with any other charger for these batteries. Charge both of them when you get them.

The battery pack came with a wall outlet charger. Just plug it into the wall to recharge it. Works great.

Option 1: Buy several aftermarket batteries and take them along fully charged for spares. You can get them for less than $10 each on Amazon. Optiion 2: Buy a solar charger. On 2nd thought, that might not work in a rain forest. Best of luck for a safe trip.

As far as I know there is no way to charge a battery outside of the laptop.

The power source has to be plugged into a wall outlet. You could possible retro fight a USB adapter if you know how...

Nope !! I've tried that ! Lol. It only charges the battery and the USB whole plug in . If you want that capability you might as well buy a portable charger. I've boughten 2x 12$ from Amazon already. Great stuff.

I never got them....they were unable to ship them from China....I do have another brand and you charge them by taking the smaller usb into the small usb port and the regular usb side into a larger sorce usb, like a laptop or car charger. Good Luck.

I always charge my batteries in the charger plugged into an electrical outlet. I have never tried to charge it using a USB cord. I had purchased a dual charger from Amazon for my camera that will work in an electrical outlet and as a car charger. It is really handy when I travel.

Unfortunately they DO need to be plugged in all the time in order to be used. For outdoor use you will need a portable power source. I recommend Paul C Buff's Vagabond Mini Lithium portable power. It's light weight, easy to carry and it costs less than $250.

Sara, did you ever find out about these units running on batteries? I too am looking for a unit for camping. Thanks.

If you're lucky, you recharge via USB, assuming your device still works. These are cheaply designed and requires a special cord which is fragile.

There are higher output non-rechargeable batteries. These wouldn't power a device I have which will run for about 8 hours with Energizer Ultimate Lithium. I'm groused I can't seem to find a rechargeable that'll power the device.

That's a good question, Joan, and I do not have an answer yet. The battery can probably charge through the USB connection and a phone charger. Since the battery itself has no indication of whether it is taking a charge or not, I will need to dig out my voltmeter from wherever I left it and test this.

I don't see any place to plug one in. We've had our in the back yard for quite a while and have only replaced the batteries once. Maybe an electrician could rig something up.
