Check out the NEWLY REDESIGNED Micro-Start XP-3 PPS (Personal Power Supply). The XP-3 is one of the smallest Jump Starter PPS units. It easily fits in your pocket or stows in your saddlebag, so you can have back-up power anywhere you go. Never worry about coming back to a dead car battery, or USB devices running low on power. The XP-3 solves it all. It can be conveniently recharged itself via Micro-USB tip.
Now the XP-3 is only recharged via USB, so its kit no longer has the bulky wall and mobile chargers. Charge USB devices or the XP-3 itself with the same USB cable! Now the Carry Case is smaller too (photo shows previous case).
