Yes, you can. It's just the same as the original battery that comes with your phone - only it lasts muuuuch longer.

This set comes with 2 batteries and a charger that plugs straight into the wall. Your "extra" battery docks into the charger. Now, with that being said, you can still charge your phone by it's original charger OR if you have a USB cable (This set DOES NOT COME WITH A USB CABLE) you can plug the "wall charger" that is charging your extra battery up via a USB cable also instead of charging it straight into an outlet. I have used my regular USB phone charger to charge my phone with one of the batteries in it; I have used a car charger to charge it; and I have also used the charging dock that came with the batteries. All methods work fine ;-)

I think so.. but I just pop a freshly charged battery in before I go to bed.

Once you have properly fully drained and charged your batterys a few times yes.Best investment I've made yet!

You can charge phone by use included USB charger connect to the charge dock. Or you can take out your cell phone battery and put the battery in the charger dock to charge your battery over night. I put one battery in the charge dock all the time so when I forgot to charge my phone, I always have a spare battery to use.

I bought it to be able to charge at night or whenever I needed to do so. It may be you can use a usb, I am not very technical.

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 know about 'supposed to', but I plug the charger in every 3-4 days. I look at the battery before I go to sleep, and if it's much under half-charged, I plug it in. I use it for 15-30 minutes in the morning as a SAD light as well as for the dawn simulator alarm. If you use it less as a SAD light, the charge will last longer.

Mine came with a charger that uses a USB connector. I does not seem to hold a charge for very long. The best I can manage is about an hour of use. It has a separate connection that also allows you to program it. If you don't get that you are out of luck. I also use my apple wall connector to recharge because it the USB connection will fit there too.

Iuse the USB charger to charge the battery that is in the radio. I have not charged my spare battery, becuase once you start charging and discharging them, they begin to wear out.I will use the 1st battery until it won't hold a charge any longer, and then install the 2nd battery.

I charge it with the usb. It doesn't last long. I am going to return it. Doesn't really work good if needed while out.

Hi, to charge the battery has to be removed it. The usb is only to import images.

You also need to set it to alarm to go off to keep the battery from completely draining. I have a 3 cell 11.1v battery so I have mine set to go off when each cell reaches 3.7v.

Hi Ashley, just to be clear, the unit only charges batteries when plugged into the wall outlet. Also one thing that might not be apparent is the fact that while you can charge electronics using the USB charger, it does NOT charge them while you are charging anything else. If you are charging a few AA batteries and plug a cell phone into the USB plug, the unit will wait until the AA batteries are charged BEFORE it will charge the cell phone plugged into the USB port. Keep in mind, you can charge something through the USB port while batteries are discharging. However, once the batteries are done discharging, the USB charging port will shut off when the batteries start to charge. Hope this helps.

Plug it in an leave it charging until fully charged! As in over night. Most of these micro devices have a control chip that needs to be fully charged to wake up the unit. That should solve the problem. If that that doesn't work, return it, but I bet it will. This unit may NOT work when plugged in. The safety feature is to avoid a 110 shock. Rest easy. Once it's charged and operative it's got hours of fun in each charge!

I alwasy 100% fully charge a battery (overnight) one time before using it. This helps mitigate the "memory effect" where batteries can not be charged to their full capacity. Simply connect the battery to the system and allow it to charge. Just don't let the battery ALONE power the system until it is fully charged.

There was a red pin that came with it to turn off the alarm, but I'd assume you've lost that. So the best thing is to charge it to "shut-it-up". If you've lost the original charger (as mentioned in a comment), you can use any 12V car charger connected to the jumper clamps. You will need to have the switch for the jumper cables "on" while charging and be sure the clamps make metal-to-metal contact (the outside of the clamps on the peak unit are plastic, so the chargers clamps need to go inside them touching the metal jaws). Otherwise be sure red clamps never touch black. To tell when it's charged while charging this way, the "battery indicator" LEDs will show the 2 green with it at ~12.5V pretty quickly, but that's not even close to fully charged (see my review about how they light up during "charging" versus "draining"). You'll want to take it to about 14V, then it's "fully charged" (and you'll need to measure that yourself with a meter).

The way it comes out of the box you halve to charge with the USB. You can buy a charging adapter from Amazon. I had a suitable charger that has the same wattage, so I didn't buy one. Either way of charging works great.

Theres an app that does that. Just do it 3 hours before bed. Let it die. Plug it in turn it on charge over night then use regularly repeat 6 or 7 times a little bit of a hassle i know. But its worth it.

You should have a nice white colored charger that comes with it. Just plug in and leave it overnight.
