Omnicharge Omni 40+ High-Capacity Portable Power Bank

Overview

The Omnicharge Omni 40+ occupies a category unto itself: a portable power bank running at the maximum battery capacity the FAA permits on passenger aircraft. At 38,400mAh and 142Wh, it sits exactly at the TSA carry-on limit for lithium batteries, delivering nearly double the energy of the Omni 20+ in a unit that still fits in a carry-on bag. The port lineup matches the ambition, with a 100W AC outlet, a 100W USB-C PD port, two 30W supplementary USB-C ports, two 18W USB-A QC 3.0 ports, and a programmable 100W DC barrel output.

Performance

Combined output across all ports reaches 150W, which is the figure that defines real-world use. A single 100W USB-C port sustains full-speed charging for a 16-inch MacBook Pro, while the AC outlet handles any laptop with a standard three-prong adapter. The programmable DC barrel port supports an adjustable voltage range of 1 to 25V at up to 100W, making it compatible with drones, portable monitors, and professional AV equipment that requires specific voltage settings.

Charge estimates from a full bank include approximately 16 action camera charges, 10 DSLR charges, 8 smartphone charges, 4 drone charges, 4 tablet charges, and 2 full 15-inch laptop charges.

Design & Portability

The Omni 40+ measures 9.5 x 2.7 x 2.5 inches and weighs 2.35 lbs. The rubberized enclosure is solid and resists the kind of knocks and drops that accompany location shoots or field work. The front-mounted OLED display provides real-time power, temperature, and port status readouts. A USB hub mode lets the Omni 40+ function as a data hub when connected to a laptop via USB-C, which is useful for photographers and videographers who want to transfer files while charging.

Who Is It For?

The Omni 40+ is for working professionals who push power banks to their limits. Documentary filmmakers keeping camera batteries, a laptop, and monitoring equipment charged between takes at a remote location. Overlanders running a CPAP machine, phone, and navigation tablet overnight. IT professionals traveling internationally with multiple laptops who cannot afford gaps in coverage.

Verdict

The Omnicharge Omni 40+ is the most capable TSA-approved portable power bank available. It does not compete on price per mAh with budget banks, because budget banks cannot put a real AC outlet in your backpack. For professionals whose work depends on continuous power, the 40+ is a serious tool that justifies its serious price. Rating: 4.6 out of 5.
