Best power bank for Lenovo Legion Go 2? USB-C PD 65 W and 20,000-25,000 mAh

The safest choice is a power bank with a USB-C PD port rated at 65 W and a capacity of 20,000-25,000 mAh. That is the power the Lenovo charger delivers, so the console gets what it is designed for.

If you don't want to spend long searching, the most frequently bought option is the Anker 20,000 mAh with a built-in USB-C cable. It delivers up to 65 W from a single port and means you don't have to carry a separate cable.

If you want a larger energy reserve, look at the 25,000 mAh versions. I explain below how much they really add.

Why 65 W, when a weaker power bank will also connect

According to Lenovo PSREF, the Legion Go 2 (model 8ASP2) has a 74 Wh battery with Rapid Charge, which means up to 50% in 30 minutes. The Lenovo charger is a 65 W USB-C unit with USB PD 3.0, although in some configurations it is not included in the box. Notebookcheck notes that this charger is enough for playing and charging at the same time.

This leads to a simple rule: the closer to 65 W, the lower the chance that the console will keep losing power even while plugged in. The 8.8-inch 144 Hz OLED screen and the powerful processor have their demands.

A 20-30 W power bank will also extend your play time, but with a more demanding game the console may still drain despite the cable. For lighter titles that is enough, but for newer games not necessarily.

Charge through the USB-C port on the console and use a cable that supports 65 W or more. A thin headphone cable can undo the benefit of buying a good power bank.

Fun fact: Lenovo also sells the Legion Go 2 in a version without a charger in the box, as seen in the configurations on PSREF.

Below we have gathered power banks with a capacity of 20,000 or 25,000 mAh and a single-port output of 65 W or higher, meaning ones that don't fall behind the Lenovo charger.

Recommended power banks for Lenovo Legion Go 2

How much 20,000 mAh and 25,000 mAh will add, and when to plug in

Power bank capacity is given for 3.7 V cells. On that scale, 20,000 mAh is about 74 Wh, and 25,000 mAh is about 90 Wh. Some of the energy is lost in the converters, so roughly 3/4 of what is stored in the cells reaches the device (according to Anker).

In practice, this means 20,000 mAh will deliver about 55 Wh, or roughly 3/4 of the Legion Go 2 battery. The 25,000 mAh version will deliver about 67 Wh, which is almost the entire battery. This is a rough estimate, not a manufacturer's promise.

What does this mean when buying? Twenty thousand is the choice for a trip where weight matters and you have access to a power outlet in the evening. Go for twenty-five thousand when you won't see a charger for a longer time.

Fun fact: a 25,000 mAh power bank will deliver almost the entire 74 Wh battery, because about 67 Wh reaches the console. This comes from Lenovo and Anker data.

When should you plug in? For a demanding game, do it from the start of the session, not only when the battery is low. That way the power bank helps spread the load instead of putting out a fire.

With lighter games, you can play on the console's own battery and plug in the power bank when it runs lower. If you take a break, Rapid Charge at the right power level will quickly make up a good part of the losses.

Airplane and the 100 Wh limit

Power banks up to 100 Wh can usually be carried only in carry-on luggage. Do not put them in checked baggage.

The 20,000 and 25,000 mAh models fit within this limit, because their cells are about 74 Wh and about 90 Wh. Larger designs may already exceed it, so check the Wh value on the casing before buying.

Before the flight, also check the airline's regulations. Airlines sometimes add their own rules, for example about using a power bank during the flight.

Frequently asked questions about a power bank for the Legion Go 2

Which power bank for the Lenovo Legion Go 2?

Choose a power bank with USB-C PD 65 W and a capacity of 20,000-25,000 mAh. The Anker 20,000 mAh with a built-in cable is the most commonly bought variant. If you want a bigger reserve, consider 25,000 mAh models.

How many watts does the Legion Go 2 need from a power bank?

Ideally 65 W, because that is what the Lenovo power adapter provides. A 20-30 W power bank will also extend your gaming time, but with heavier games the console may still drain even when plugged in. Use a cable that supports 65 W or more.

How many times will a 20,000 mAh power bank charge the Legion Go 2?

Less than one full time. It delivers an estimated 55 Wh, or about 3/4 of the 74 Wh battery. The 25,000 mAh version will deliver about 67 Wh, which is almost the entire battery.

Does the Legion Go 2 come with a power adapter in the box?

Usually yes, it is a 65 W USB-C adapter with USB PD 3.0. However, PSREF also lists a configuration without an adapter, so check what is in the box of your chosen version before buying.

Can you take a power bank for the Legion Go 2 on a plane?

Yes, if it is up to 100 Wh and travels with you in carry-on luggage. 20,000 and 25,000 mAh power banks fit within this limit. Just in case, check your airline's rules.
