One essential device that should be in everyone's briefcase, backpack, purse, or carry-on bag is a portable power bank. These power banks can come in many shapes and sizes. You can get ones that can easily fit inside your briefcase or purse. There are also larger ones that can fit in your backpack, such as the one BLUETTI has available today. However, the one you need to consider can give your existing smart devices, like a laptop, smartphone, tablet, and even your smartwatch or wearable, a quick charge so you can use it until you get to a place where you can power up your device. Companies like Samsung, Belkin, Mophie, and Anker all make good and reliable portable power banks. A newcomer to our list is EnergyCell. They sent over their Pilot 4GS Portable Power Bank for us to test, and here is what we learned from testing this power bank for the past few months.

What we learned from testing EnergyCell Pilot 4GS

Power cord for EnergyCell Pilot 4GS Power Bank was a little shortGearBrain

I tested the EnergyCell Pilot 4GS power bank over the course of several months, taking it with me on daily commutes via public transportation, beach outings, and even keeping it in my car for those moments when multiple devices needed a quick power-up. I appreciated the slim design and the fast-charging capabilities of the Pilot 4GS, which consistently delivered strong battery performance. The power bank features three ports—two USB outputs and a Lightning connector, which can be used to recharge the unit itself and power up your iPhone or other devices. I especially liked that it could charge two devices at once, a convenient feature when traveling or sharing with someone else.

However, I did find a few drawbacks. The included charging cable was shorter than I prefer, and I generally prefer power banks with built-in or attached cables, which eliminate the need to carry extras. In terms of weight, the Pilot 4GS is heavier than some competitors, such as the Belkin BoostCharge, but it compensates for this with a durable outer case that feels rugged enough to withstand drops and outdoor use.

Overall, the best feature is its price—a fantastic value for what you get. For anyone who’s frequently on the move and needs a reliable, fast-charging, and durable portable power bank, the EnergyCell Pilot 4GS is a smart buy.
