The SP1 from XTAR is one of the most unique and versatile battery chargers we have ever seen, and it's certainly something to get excited about. As a single-slot charger, it can only charge one battery at a time, perfect as a back-up (remember "One is None!") charger to keep in the car or when traveling as it provides the all the advantages of a small, highly portable charger.

As with all XTAR chargers, safety is the number one priority. The SP1 casing is made from super tough ABS plastic that is fire-proof and ready for whatever you throw at it. Three optional charging circuits (0.5A, 1.0A, or 2.0A) allow for charging of 12 different kinds of lithium-ion battery (see below for the full list), so you can rely on the SP1 for whatever battery you need. The IC monitor will safely control the charging level and automatically terminate the current when the battery has reached capacity. Over-discharged batteries will be repaired and brought back to life thanks to the zero-volt activation feature which slowly trickles in current to the over-discharged battery. You'll get more life out of your lithium-ion batteries than you ever thought possible, and you won't have to worry about over-depletion. The spring loaded contacts eliminate the need for spaces when switching between different batteries; you won't have to deal with that headache any more.

More than just a charger, it's a portable, all-purpose power solution.

This charger is ideal for travel in more ways than one: it's designed with a USB output to allow you to charge all your USB-powered devices on-the-go. Coming in at less than five inches in length, you'll have no trouble packing the SP1 along with you; you'll be glad you did, since you won't go anywhere unprepared. The SP1 is the perfect addition assortment of backup power solutions. Take your most trusted 18650-powered light with you and the XTAR SP1 to keep it charged up, meanwhile using that same 18650 to power your cell phone, laptop computer, GPS, whatever it may be to keep you ready when the time comes. Choose the battery charger that's all you need and more; choose the SP1 from XTAR.

Awesome Little Charger!
February 11, 2015
This single slot charger is just perfect for recharging 18650 flashlight batteries. It charges all thee levels of battery, from the light-duty to energy-dense 3400 mA lithium batteries safely. The USB output is a really nice touch, the charged battery can double as an iPhone battery by switching it's charge to output. Once you get to know the modes and charge rate, it is a very nice unit that does not take up much weight or space, great for throwing in a pack for backup, and with the 12vdc input plug, you can use a solar charger to recharge the battery on the trail. You might want to get a rubber band to secure the battery in the cradle if you use it for output through the USB port, throwing the unit in a bag can dislodge the battery from the cradle if jostled about a lot.
Nice Size Nice Price Nice USB output option
Red/Green charge indicator is not friendly for red-green colorblind people. Separate LED's (red on Left, Green on right) would be much better, or switching to another color in the single indicator light. Providing a way to secure the battery in the cradle so the charger unit could be carried "in the field" as an iPhone or other USB device emergency charger would be nice.
