When your out camping in nature, you get disconnected from the bustle of modern life and can experience the reprieve of nature. Unfortunately this disconnect is a double edged sword, as some still prefer to have some connection to the rest of the world through smart phones or comfort enhancing electrical products such as heaters or fans.
To get electricity when camping away from modern infrastructure, a portable battery becomes the go to source of electricity. When camping and bringing any devices that require such as phones or heaters or fans, it is highly recommended to bring a portable battery. This will allow you to charge your devices for the brief time you are out in the wilderness and away from any electrical outlets. As the best portable battery power bank for camping, I recommend:
Panergy Portable Laptop Charger 40000mAh/148Wh AC Outlet USB Power Bank
This portable battery power bank offers a standard AC outlet in addition to USB and USB type C charging inputs. This allows you to power standard electrical devices in addition to charge mobile phones while camping. The small form factor makes it perfect for carrying in your backpack as well as it weighs only 2 lbs.
In addition to the input and weight features, this power bank comes with a flashlight built in, offering an additional utility for the night while your out camping in the wilderness. An easy to read light based display also keeps you up to date on its remaining power level.
Based on my research of power banks for the price, this one hits a sweet spot with the total charge Wh vs mAh. As per the listing it offers he battery enough juice to charge a MacBook Pro 13 over 5 times, or charge a iPhone 11 over 9 times. The AC power bank is able to charge laptops, phones, cameras, fans, and other electronic gadgets and appliances.
Overall, I consider this to be the best portable battery power bank for camping as a result of its charge, weight, and functionality.
