Features of Pocket Size Jump Starters

Each of these pocket jump starters are very similar in size and features. All have a USB out for charging your phones and tablets, as well as overload safety circuits. So which one is the best?

The Anti-gravity Xp3 was a standout with 2x fast USB out ports and a jump starting power of 400 peak amps. But you will pay extra for this feature. So if you want the greatest, but not worried about the price, check out the Antigravity XP3 it would be the best here.

If you need a reliable and feature-rich car pocket jump starter, then our Number 1 pick is the DBpower 300. AKA – DJS40. We actually use this one for our everyday commute for a Toyota Corolla. Along with using it to charge the kids phones and tablets while on a road trip in the car.

It’s also smart enough to start a Toyota Prius. We tested the DB Power DJS40 the other month when a work colleague had a flat battery on his Prius. We were able to come to his rescue and jump-start his Prius. Simply amazing for such a small unit.

It’s better to use one of these smart jump packs, rather than a direct cable car to car jump start. This is because portable boost packs have built-in protection like –

  • Over Current Protection
  • Short Circuit Protection
  • Overload Protection
  • Over-voltage Protection
  • Overcharge Protection.

This protection makes them very safe to use. Read on for more in-depth reviews and videos on each of these car pocket jump starters.

How to use the “BOOST BUTTON” on the XP-3 Smart Clamps?

In most situations, you will not need to use the Boost Button on the Smart Clamps. The “Boost” Button is designed to allow for Jump Starting a Vehicle when the battery has very low voltage or no voltage reading. In these emergency situations, the “Boost” Button allows the jump starter clamps to be energized to start the Vehicle for emergency Boost Starting.

CAUTION MUST BE USED WHEN PRESSING THE BOOST BUTTON! THE CLAMPS ARE LIVE WITH ENERGY ONCE PUSHED.

WARNING PLEASE NOTE THE FOLLOWING.

A) The Smart-Clamps must be connected to the XP-3 for the “Boost” Button to operate. It needs power.

B) BEFORE pressing the “Boost” Button double check to make sure all connections are correct. Once the “Boost” Button is pressed the Clamps will have “live” 12v voltage at the Clamps. Always connect Red Clamp to Positive (+) Terminal of Battery. Black Clamp to Negative (-) Terminal of Battery.

C) You will hear a “click” when you have pressed the boost button correctly, you may need a pen, fingernail or edge of a key to press the button correctly due to the “Boost” Button being indented in the Smart-Clamp Housing.

D) Once the “Boost” Button is pressed you will have 25 seconds to attempt your jump-start. After that time the “Boost” will turn-off. You will need to press the Boost Button again to re-engage the Boost feature.
