Easy to use

Easy-to-Use Power At Your Fingertips

Powers 12V Devices

You can never have enough outlets, especially when you're working outside. This system lends a hand with a convenient built-in 12V DC outlet that is ideal for plugging in lighting, recharging tools, or a variety of other uses on the jobsite or at the campsite.

Instant AC Power Availability

When there's no electricity in sight, a power inverter can be a life-saver. This unit has a built-in inverter with a 110V AC power outlet providing up to 400 Watts of electrical power.

Keeps USB Devices Running

From the worksite to the campsite to your backyard, never be left without your iPod or MP3 player, smartphone or tablet. The PowerTunes unit has dual built-in USB power ports that can power, play and recharge your USB devices wherever you are.

Jumpstarting Power

Quick-connect clamps, heavy-gauge cables and a powerful 18Ah battery deliver the punch you need for fast, easy jumpstarts.

Versatility that Keeps You Humming Along

FM Radio that Goes Where Your Powerpack Goes

This handy portable unit is called PowerTunes for a reason. Besides being a complete powerpack system, there’s also an on-board FM radio with easy-to-read LED screen and built-in 4in., 5 Watt sound speaker to deliver your favorite music — anytime, anywhere!

Plug In Your Own Music

If an FM radio's not enough, PowerTunes also includes an AUX cable port with right-angled AUX cable, making it easy to plug in your own iPod, MP3 player, smartphone, tablet or even a CD player or other small electronic device. A built-in device holder keeps your own music right at your fingertips.

A Portable Inflation Station

Tires need air? Want to inflate an inner tube? The high-output 150 PSI built-in inflation function is like having your own inflation station, with a gauge built right in. Perfect for most everyday inflation jobs.

Keeps you humming along
Compact yet tough

Compact, Yet Tough

Stands Up to the Elements

The PowerTunes powerpack is built tough, with a durable hard plastic shell that's designed to withstand the rigors of most environments.

Cables You Can Count On

Rugged copper-clad booster cables deliver the reliable, heavy-duty performance you're looking for to get the job done. Best of all, the handy easy-access cable design and spring-loaded clamps make for quick and easy battery hookups.

Space-Saving Size

The portable PowerTunes unit loads all of these great features into a compact 9.05in.L x 14.17in.W x 12.99in.H overall size, so you can get a lot done while only using a little space.

Dependability that Won't Leave You Stranded

Loaded with CCAs

This high-output system delivers the cold cranking amps you need to get most batteries started — even in the most adverse conditions. PowerTunes delivers jumpstarting power that will start most 6-cylinder (3.0L) engines without the need to connect to another car battery.

Maintenance-Free Design

The hassle-free design is powered by a maintenance-free, 18Ah deep cycle sealed battery with AGM technology for long life. The battery is also replaceable, so there’s no need to throw the whole unit away when the battery stops functioning. Just swap in a new battery and you’re good to go.

Easy to Recharge

When the PowerTunes' battery starts running low, all you need is a wall outlet. Just plug in the AC adapter (included) to quickly get your system recharged and running at peak performance again. A 70in.L, 12V DC charging cable is also available (Item# 27345, sold separately) to charge your PowerTunes unit right from your vehicle. An optional solar charger (Item# 33922, sold separately) adds even more versatility.

At-a-Glance Battery Level Checks

Don't get caught short. An easy-to-read digital battery status indicator is conveniently located right on the front of the PowerTunes powerpack, so you can check the remaining battery voltage with one quick look.

Easy-to-Add Battery Capacity

A 12V, 18-ga. power cable with clips (Item# 28738, sold separately) is available, allowing you to connect to another external battery to increase capacity of your PowerTunes.

Dependability that won't leave you stranded

Safety First

Safer Jumpstarts

Reverse polarity connection protection features an LED indicator light and an audible alarm to warn you if the cables are improperly connected. The early warning allows you to correct the problem, preventing damage to the system and the batteries.

Quick and Sure Mode Control

The push-button inverter/USB function and the radio function have separate on/off switches, while the jumpstarter uses a rotating switch, offering completely individualized mode control.

Overload Protection

No worries about overloading the system or running the PowerTunes unit when it's too hot. And with an integrated 15 Amp fuse, current spikes or excessive current will no longer cripple your entire system. Built-in automatic overload, overcharge and overcurrent protection offer the safety you need, quickly shutting down PowerTunes when necessary, BEFORE any damage can occur.

A Heads-Up for Low Batteries

Never draw the battery completely out of power. A low battery alarm delivers an audible signal to alert you when inverter draw from the battery is below satisfactory levels. Auto shutdown also automatically turns off the speaker/radio when the battery is running low.

Use It Anywhere

A Versatile Choice

The PowerTunes, with its convenient carrying handle, goes wherever you need it, providing power just about anywhere. From extra power at the jobsite to jumpstarts in your own driveway, at the mall parking lot, near a backwoods cabin, or wherever else you can imagine, you'll get dependable performance on the go.

All-Purpose Performance

Whether it's inflating a volleyball on the beach, powering up a radio or MP3 player while you tailgate, recharging your phone at the campsite, providing light at the hunting shack or running the depth finder on your boat, PowerTunes has hundreds of uses, no matter where your life takes you.
