The Best Portable AC Power Supply
If you want to power or charge a small AC device, such as a laptop, when the power outlets are out of range, you must purchase the ChargeTech Portable Power Jack (27 Ah). It's essentially the same as a USB battery, but with a higher capacity and a power outlet. The ChargeTech stood out among the small models that we tested because it offered the best balance between size, capacity and price. The size of a small bound book is compact enough to fit in a laptop bag, backpack or carry-on bag, but it holds enough energy to fully charge a large laptop or load more models. small two or three times. If you need to power more than a laptop or other small device, but a gas generator is out of the question, we love the Goal Zero Yeti 400 solar generator for its superior capacity, power and superior workmanship - even if it's too big and too heavy to lug around all the time.

But a pack with a standard power outlet is a more versatile power source, suitable for bizarre situations where USB will not do the trick. For example, if you often work away from a traditional office, or if you have a laptop with a lower battery life, a portable power supply allows you to go further than just the table near the cafeteria.

The more power you need, the more expensive and cumbersome AC power is.

Although the Portable Power Outlet is not cheap enough to be an impulse purchase, many laptop users will have many opportunities to enjoy it.
