This depends on the size of the motor and state of charge, but regular 4 and 6 cylinder cars about 20 times or more, and V8s about 10 times in a row. Make sure your connections are good, and do not jump-start with XP-3 below 3 capacity lights lit.

The MICRO-START XP-3 can charge the average cell phone about 6 times depending on the size of the cell phone’s battery. XP-3 has 8000 mAh of capacity. It can generally charge a tablet from 2 to 3 times. This depends on the size of the tablet and if you are on the internet or playing games which uses more power.

The MICRO-START can charge a phone in about 40 minutes to one hour. It depends on the phone, and of course whether you are using the device while it’s charging. The XP-3 has a 2 Amp charge rate at its left side USB port to charge electronics more quickly.

On average the MICRO-START can hold a charge about 6 months. This will depend on the conditions the MICRO-START is stored in. Heat and cold fluctuations can affect this. It is best to check the state of charge at least once every 3-4 months.

To check the state of charge on the MICRO-START, press the power button. The XP-3 has 4 lighted capacity indicators which will show the state of charge. Each light is equal to 25% capacity. XP-3 can charge devices until no lights are lit, but should only be used to jump-start vehicles with a minimum of 3 lights lit (75% capacity).

  • 1 bar = 25%
  • 2 bars = 50%
  • 3 bars = 75%
  • 4 bars = 100%

Our MICRO-START power banks all meet the FAA criteria for Lithium batteries/external chargers allowed as Carry-On items. But they cannot be in Checked baggage. The guidelines state that consumer-sized Lithium-Ion batteries, up to 100 Watt-hours (Wh) per battery, are allowed on planes. All MICRO-STARTS are under that limit (Watt-hours is printed on the back of each MICRO-START). For more information about carry-on and portable devices, refer to the FAA website.

Please also check with your Airline before taking your MICRO-START because each Airline may have different guidelines.

To recharge the XP-3, you may use any standard USB cable with Micro-USB tip. For jump-starting, do Not use any clamps other than the Smart Clamps provided with your XP-3 kit. We offer replacement chargers and clamps if needed.

For charging your devices, you may use another USB cable you may already have for your device.
