Does United Airlines Allow Lithium Batteries

This bag fit my needs: - Fits under the seat on a United Airlines USA domestic flight (Boeing 737) despite being slightly larger than the allowed personal item size - Stores all my camera gear (4 small lenses, 1 telephoto lens, 2 camera bodies, 1 drone, 16 MacBook Pro, tripod, and accessories) - Feels not uncomfortable with 32+lbs fully loaded - Keeps my gear safe through snow, rain, sand, mud, and airport transit Biggest annoyance: The interior pockets are too tight to hold anything thicker than a cell phone. You end up needing to shove everything into the large compartment and fish around for it.

Excellent backpack. Main requirements for me were to fit United Airlines personal item dimensions and deep enough to hold a Canon 1D (about 6 1/2" deep) 1 lens (17-40) and charger. It satisfied both. Top compartment was used for additional small carry on items. Tested in Hawaii on two crater treks and it worked great. Thick padding on the back, Fit and finish were excellent. Will be using it on my upcoming big trip.

Very versatile, You can use lithium batteries to power it

Nothing beats these lithium batteries...they don’t die.

I already had two of the Nikon EN-EL15c Rechargeable Lithium-Ion Batteries, but I recently purchased the Nikon MB-N11 Power Battery Pack with Vertical Grip for my Z7ii which takes two of the EN-EL15c batteries, so having a spare made sense to me. I also own several EN-EL15 batteries for my D850 and have experience zero problems with Nikon batteries.

Like the ability to change 2 batteries at the same time and keep them together. Thinking about getting another for my other two Lithium Ion batteries.

I love the compact size of the charger, and it seemed to charge my lithium batteries quicker than my last charger.

These lithium batteries are very light and last a long time. Charger works well too.

It works wonderfully charging the lithium battery included for my A6500.  Does exactly what it is supposed to do.  What else can you say.

I use this to charge lithium ion batteries for my Leica camera and my other small lithium batteries for my Panasonic Lumix camera.
