Anker - Laptop Power Bank (25K, 165W, Built-In and Retractable Cables) - Black

The Anker Power Bank (25K, 165W, Built-In and Retractable Cables) is flight-approved and can be brought on airplanes for use in America, Europe, Asia, and other regions, as long as it complies with airline regulations. Batteries with a capacity of 100Wh or less are permitted on airplanes as part of carry-on luggage. The capacity of the Anker 25K Power Bank is within this limit (25,000mAh / 165W), so it is allowed. However, you must ensure: The power bank is placed in your carry-on luggage (not checked luggage). You confirm with the airline about their specific guidelines, as government and commercial flight regulations are subject to change. Always check the battery capacity label located at the bottom of the power bank to verify its approval.

Based on your description, the blinking "two eyes" on the display is a protective error indicator, not a normal charging state. This usually means the power bank has detected an abnormal condition (most likely overheating or excess current/voltage). Since it works at some other times and fails at others, the problem is intermittent. Here’s what to check and do: 1. Check for overheating (most common) If the power bank or the charging cable feels hot (even slightly), let it cool down for 15–30 minutes before retrying. High ambient heat (sun exposure) or charging multiple high-power devices simultaneously can trigger this protection. 2. Verify your charger and cable Make sure you’re using a 65W+ USB-C PD charger (or the original that came with it) and a high-quality cable rated for 100W+. A damaged or non-PD cable can cause a voltage spike and trigger the error. 3. Reset the internal logic Unplug everything and press and hold the power button on the power bank for about 10 seconds to force a soft reset. Then wait 2 minutes, plug in the charger, and press the button to start charging again. 4. Test with a different port/cable Try the other USB‑C port or swap the cable to rule out a loose internal connector. 5. If it still fails: The battery management system (BMS) may be faulty, or a cell may be unbalanced. This is an internal issue not fixable by the user. Recommendation: If the issue persists after steps 1–4, contact Anker support with your order/purchase details. This may be covered under warranty, and they will replace the unit or walk you through further diagnostics. Do not open the unit, as it contains lithium cells and high current rails.
