Portable Lithium Power Banks

Stay Charged When the Outlet Is Miles Away

A dead phone on the trail, in the terminal, or in the middle of a workday cuts you off from maps, tickets, clients, and people who need you. These portable lithium power banks put extra charges in your pocket, bag, or glove box so phones, tablets, earbuds, watches, and even many laptops keep running long after the wall charger is out of reach.

Lion Energy packs this collection with compact 10,000mAh daily-carry banks up through high-capacity 27,000mAh travel units. Choose wired USB, magnetic wireless, or both—and leave the day with power still in reserve.

Carry Backup Power That Actually Gets Used

A power bank only helps if you bring it. These units stay light enough for a pocket or sling, charge more than one device, and recover quickly so they are ready for the next trip.

• Hours More Screen Time – 10,000mAh models cover multiple phone top-offs. Step up to 20,000mAh or 27,000mAh when you share power, run a tablet, or spend a full day off-grid.
• Wireless When You Want It – Snap a MagSafe-ready iPhone to a magnetic pack or drop a Qi phone on a wireless pad. No hunting for the right cable at the worst moment.
• Fast Ports for Everything Else – USB-C Power Delivery and USB-A outputs charge earbuds, watches, cameras, and tablets. Higher-output USB-C on the largest banks can feed a laptop when you can't find a seat near an outlet.
• Built-in Light – Select models include an LED lamp or SOS mode so you can find a tent zipper, a gate code, or a dropped key without draining the phone you just saved.
• Travel-Ready Lithium – Capacities in this category stay within common carry-on limits, so backup power can fly with you instead of riding in checked luggage.

Pick a Capacity for the Type of Day You Live

The right power bank needs to match how long you stay away from wall power.

• Pocket and Purse Carry – Slim 10,000mAh banks handle a workday, a commute, and a night out. Magnetic wireless models stick to the back of a compatible phone so charging happens while you walk.
• Weekends, Flights, and Family Days – Mid-size 20,000mAh banks refill several devices and still fit in a backpack. Wireless plus multiple USB ports mean kids, partners, and work phones share one pack.
• Long Travel and Laptop Duty – The highest-capacity banks in this lineup push toward 27,000mAh with multi-device wireless and high-watt USB-C so a work bag stays productive on a tarmac delay or a cabin table.

Every pack in this category uses lithium cells sized for portable use. Charge the bank at home, drop it in the bag, and treat outlets as optional.

Leave Home Knowing the Phone Will Last

Campers keep maps and headlamps alive after dark. Travelers board with tickets, boarding passes, and a charged camera. Commuters finish the day without hunting a café for a seat by the wall. Lion Energy backs these power banks with a five-year warranty, so the pack you buy for this season still earns a place in the bag for years to come.
