A1640 PowerCore Solar 10000 not included in September 2025 CPSC recall of Anker power banks
The September 18, 2025 CPSC recall of Anker power banks (about 481,000 units) covers models A1647, A1652, A1257, A1681, and A1689. The A1640 PowerCore Solar 10000 is not among the recalled models. This finding came from the CPSC recall notice (Spanish version) returned by the search 'CPSC Anker power bank recall 2025 A1642 A1647 A1652 fire burn hazards'.
What to check. If you own an A1640, it is not part of this recall. However, check your serial number on Anker's recall page if you have any Anker power bank, as recalls are serial-number-specific.
A1640 not included in June 2025 CPSC recall of Anker PowerCore 10000 (model A1263 only)
The June 12, 2025 CPSC recall (about 1,158,000 units) covers only model A1263 of the Anker PowerCore 10000. The A1640 PowerCore Solar 10000 is a different model and is not included. This finding came from the search 'cpsc.gov Anker recall power bank model numbers'.
What to check. The A1640 is not part of this recall. The recalled A1263 is a different PowerCore 10000 variant with a different model number.
A1640 manual documents high-temperature indicator to prevent overheating
The official Anker A1640 user manual describes a high-temperature indicator feature designed to prevent overheating. The Turkish manual translation further states: 'Yüksek sıcaklık göstergesi kırmızıya döndüğünde bu, PowerCore Solar'ın sıcaklık sınırını aştığı anlamına gelir. Tekrar kullanmadan önce soğumasını bekleyin.' (When the high-temperature indicator turns red, it means the PowerCore Solar has exceeded its temperature limit. Wait for it to cool down before using again.) This finding came from the search 'Anker PowerCore Solar 10000 A1640 fire'.
What to check. The A1640 includes a built-in safety feature that alerts the user when the unit exceeds its operating temperature. This is a design feature, not a documented failure.
Anker CPSC recall does not include the PowerCore Solar 10000 (A1640)
The primary CPSC notice (Sept 18, 2025) names only A1647, A1652, A1257, A1681 and A1689. The A1640 (PowerCore Solar 10000) is not among them, and the earlier June 2025 recall was for the PowerCore 10000 A1263, a different product.
What to check. Do not assume the A1640 is recalled. Secondary articles describe the second recall as covering a model range (A1257-A1647) that could be read to include A1640, but the authoritative CPSC notice lists specific models and A1640 is not one of them.
Owner reports PowerCore Solar 10000 (A1640) overheats during solar charging
An owner review of the A1640 reports that in summer the solar panel surface temperature exceeds 60 degrees Celsius and that the reviewer worried the heat would damage the battery cells, advising not to use it in that state.
What to check. If you plan to solar-charge this unit, be aware it can get very hot in direct summer sun (surface above 60C per one owner), which the reviewer worried degrades the cells. This is a Japanese-market owner report, not a US documented incident, and no fire incident tied to the A1640 was found.
Owner reports solar panel surface temperature exceeding 60°C during solar charging, risking battery cell damage
A Japanese Amazon reviewer of the Anker PowerCore Solar 10000 (A1640) reports that solar charging causes the unit to overheat to the point of potential battery cell damage, noting the solar panel surface temperature exceeds 60°C in summer. This is an owner observation, not a documented safety event like a fire or recall. This finding came from the search 'Anker PowerCore Solar 10000 A1640 overheating'.
What to check. The A1640 has a high-temperature indicator (per its manual) that warns when the unit exceeds its operating temperature limit. Owners should avoid leaving the unit in direct sunlight for extended solar charging, especially in summer, as the heat may degrade the battery cells.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
