Which is better for jumping a full-size truck?

The Stanley. Its 1,000 peak amps and 500 starting amps are rated for most 4-, 6- and 8-cylinder vehicles. The Rexing publishes no amp rating and targets cars, motorcycles and ATVs.

Which one inflates tires better?

The Rexing. Its 150 PSI compressor has an LCD pressure readout with adjustment controls and unit selection. The Stanley has a compressor but no digital gauge listed.

The Stanley's lead-acid battery is the proven design, backed by 2,190 ratings at 4.1 out of 5. The Rexing's 7200mAh lithium pack has one rating, and that buyer already wonders how long the battery will last.

Is the Rexing worth it at $71.99?

Yes if you want one small unit for tire top-ups and small-engine jumps. It was $71.99 on October 31, 2026 and has hit $99.99 on November 2, 2026, so buy near the low.

Can either charge my phone?

Both can. The Rexing has a USB-A output; the Stanley has two USB ports. Neither is a substitute for a dedicated power bank.

Which is safer to connect?

The Stanley has a reverse-polarity alarm and is ETL listed. The Rexing relies on intelligent clamps and lists no alarm.
