Best Power Banks for Bug Out Bags: Anker vs. Nitecore

In a modern evacuation, a smartphone is not a toy; it is your GPS, your map, and your radio. Keeping it alive is a top priority.
While you can buy cheap power banks at gas stations, they are often heavy, fragile, and fail in cold weather.

For a Bug Out Bag (BOB), you need a specific balance of high capacity (to last 3 days) and low weight. The market is currently split between the consumer king Anker and the tactical specialist Nitecore.


Goal: 10,000mAh minimum (2-3 full phone charges).

Nitecore NB10000 is 40% lighter than standard bricks.

Cold weather resistance is critical for winter survival.

The Ultralight Choice: Nitecore NB10000 Gen 2

The Nitecore NB10000 was designed specifically for trail runners and military use. It uses a carbon fiber shell to achieve a weight of just 5.29 oz (150g).

It is shockingly thin and durable. If you are counting ounces in your pack, this is the only choice. It costs more than standard banks, but you are paying for the weight savings.

The Durable Workhorse: Anker PowerCore

Anker is the standard for reliability. Their PowerCore 10000 or 20000 units are slightly heavier and bulkier than the Nitecore, but they are often half the price and incredibly robust.

If weight is not your primary concern (e.g., for a vehicle kit or home blackout kit), Anker offers better value per dollar.

Which brick belongs in your pouch?

Best for Hiking/BOB: Nitecore NB10000

The lightest 10,000mAh bank in the world. Carbon fiber frame. The undisputed king of ultralight preparedness.

Best for Capacity: Anker 525 (20,000mAh)

Twice the power for a similar price. Heavy, but can charge a phone 5-6 times. Great for groups or families.

Avoid: “Solar” Power Banks

Do not buy power banks with tiny built-in solar panels. They take 40+ hours to charge. Buy a separate folding panel instead.

The “Low Current” Mode

Both recommended units have a “Low Current Mode.” This is essential for charging tiny devices like Bluetooth earbuds or smartwatches, which draw so little power that standard banks often shut off automatically thinking they are done.
