The boosters from New Brights and Powerall have two USB ports, but they lack laptop connectors and ranked toward the bottom in device charging capacity.Īll of the jump starters we tested had a maximum recommended operating/storage temperature, ranging from 120 degrees Fahrenheit for the Pilot InstaBoost up to 185 degrees for the Bolt Power D28.

Spirit and Bolt Power’s booster packs have laptop adaptors and good device charging times, but only a single USB port.

The Antigravity Batteries XP-10 was clearly the best of the bunch, with two USB ports, several laptop connection options, and best-in-test device charging capacity.

These units provided strong jump-starting performance, along with good accessory charging options.

Of the 10 units we tested, we awarded Recommended status to five: The Antigravity Batteries XP-10, Spirit A8 Car Jump Starter, Bolt Power D28, New Brights Compact 12000mAH Mini Portable Car Jump Starter, and PowerAll PBJS12000R. And the second-priciest model (Noco Genius Boost GB30, $105) came in second-to-last place in our ratings. While the best-performing jumper pack (Antigravity Batteries XP-10, $125) was the most expensive, the weakest performer (Pilot InstaBoost) was not the least expensive-we paid $100 for it. Incidentally, price turned out to be little indication of performance. (Interestingly, the Revo did almost as well as the Antigravity unit in our jump-start tests.) We consider this the power-source performance to be a notable factor, as these units can keep vital devices, such as mobile phones, charged up during a power outage.

It provided power for three times as long as the poorest performers, which came from Revo and Noco. The best-performing unit was the Antigravity Batteries XP-10. Where we did see lots of variance was in the units’ abilities to charge devices, such as tablets and laptops. When the battery packs were at room temperature, most were able to successfully jump start a frozen car battery.

With both the car battery and the jump starter at zero degrees, none of the units were able to jump start even the weak car batteries, let alone a dead battery.

Then the Pilot InstaBoost struggled, dropping below its competitors in the ratings. It was when the temps dropped below freezing that the differences appeared.

Most battery packs could start a car battery at room temperature.

When it came to jump-starting vehicles, performance between the units was nearly identical. We also tested the units to see how long they could provide power to smaller devices such as tablets and mobile phones. The fourth test had the batteries cooled to 0 degrees with the jump starters at room temperature. For the third test, we chilled both the weak batteries and the booster packs down to 0-degrees Fahrenheit. In the first and second test, both the battery and the jumper packs were at room temperature.
