Anker A1383 20K power bank review: a lighter laptop-and-phone backup

Verdict: The Anker Power Bank 20,000mAh / 87W Total (A1383) makes sense for a commuter who wants one attached charging cable and backup power for a compatible USB-C laptop. It is lighter than Anker’s 25K / 165W bank, but its single-device ceiling is 65W and its smaller battery leaves less reserve. Protein Picks has not tested it. Anker specifications 25K specifications

Pros

• One attached USB-C cable means one less lead to pack for your main device.
• Approximately 431g, versus 595g for the 25K A1695.
• Separate USB-C and USB-A ports give you connection options. Anker specifications 25K specifications

Cons

• A laptop needing more than 65W cannot get its full requested power from this bank.
• The 87W headline is a shared total, not the output of one connection.
• A second USB-C device still needs a separate cable; this bank has only one built-in lead. Anker specifications

Can it charge a laptop and phone?

Plan around the laptop’s requirements, not the 87W label. Anker rates either single USB-C connection for up to 65W. That makes the A1383 a candidate for a modest-power USB-C laptop, but a demanding machine may charge slowly or draw down its own battery under load. Check your laptop’s supported USB-C input before buying. Anker specifications

Multiple devices share the output budget. The headline does not establish every cable-and-port combination, so this analysis does not promise a particular laptop-and-phone split. If maintaining laptop power while charging a phone is essential, verify that exact configuration.

A1383 or the larger Anker 25K / 165W?

These are manufacturer ratings, not sustained-output measurements. A1383 specifications A1695 specifications

Choose the A1383 when carrying less matters more than keeping several demanding devices powered. The 25K adds reserve and a second built-in cable, but also adds about 164g. For a phone-only outing, even the A1383 may be more bank than you want.

Price should settle a close decision: choose the smaller bank if its current retailer price saves enough to justify the reduced capability. We have not verified a current Amazon price difference. See the 25K / 165W analysis for its more complex power-sharing limits.

What does 20,000mAh mean in practice?

It is a cell-capacity rating, not energy delivered unchanged to your devices. Charge-Test measured roughly 61.5–66Wh of usable output across different loads on its A1383. Those results suggest a useful reserve, but do not establish a full laptop recharge count: device battery size, conversion losses and use while charging all matter. These are Charge-Test’s measurements, not ours. Charge-Test measurements

Who should buy it, and who should skip it?

Buy it for occasional laptop backup and phone top-ups when one integrated cable and lower carry weight suit your routine. Skip it for sustained high-power laptop use, two attached cables, or maximum time away from outlets.
