Anker 733 Power Bank Explosion Highlights Broader Safety Concerns as Over One Million Units Recalled

A recent social media post by data scientist Chris Albon, praising a portable battery from what he described as a "candy company" for its ultralight design and "instant cult status" among backpackers, has unexpectedly drawn attention to significant safety concerns within the portable power bank market. Albon's tweet, which lauded the product as his "favorite of the year," was met with a stark reply from a user stating, "THEY CANCELED MY ORDER CAUSE THEY EXPLODE NOOOO.

This cautionary response aligns with recent reports of power bank failures, including a detailed account on Reddit concerning an Anker 733 Power Bank (GaNPrime PowerCore 65W). A user reported that their Anker 733 Power Bank exploded while charging, describing a "very loud" event accompanied by "a lot of smoke and a small fire." The incident underscores the potential dangers associated with these popular devices.

The explosion of the Anker 733 follows widespread safety actions by regulatory bodies. The U.S. Consumer Product Safety Commission (CPSC) has overseen the recall of over one million Anker power banks due to fire and burn hazards. Similarly, the Australian Competition and Consumer Commission (ACCC) has issued warnings regarding a growing number of power bank recalls, noting that "some consumers have suffered serious burn injuries, and some have had their property damaged because of power banks overheating and catching fire.

Industry experts suggest that power banks featuring integrated AC chargers, like the Anker 733, can present particular risks. These designs combine the heat-generating components of a charger with lithium-ion batteries within a compact, often sealed, casing. This can lead to elevated internal temperatures, which may accelerate battery degradation and increase the likelihood of thermal runaway and combustion.

Given the increasing popularity of ultralight power solutions for travel and outdoor activities, stringent safety standards are crucial. Consumers are advised to prioritize products with recognized safety certifications, such as UL listing, and to adhere strictly to manufacturer guidelines. Safety recommendations from the ACCC include avoiding charging power banks on flammable surfaces and immediately discontinuing use of any device exhibiting signs of damage, overheating, or swelling.
