Black Friday power banks 2026: is the discount real?

On November 27, 2026, a Friday. It’s the Friday after Thanksgiving, the fourth Thursday of November (Nov 26, 2026). Each store announces its own sale period on its website.

The only way to know is to compare with the same model’s history. The Radar compares today’s price with the median of the last 30 days for that power bank in the price history and ignores the "was" price the store crosses out. On Nov 6, 2026, no model is 5% or more below the median, with enough history.

It depends on the model. The Radar saves the price of each power bank every day and compares it with the 30-day median. The series shows how the price has moved so far, not what the store will do on Nov 27, 2026.

On November 30, 2026, the Monday after Black Friday (Nov 27, 2026). The date comes from the calendar rule; each store announces its own sale period.

Each store sets its own warm-up period and announces it on its website. The Radar only publishes a store’s date with an open source and, without one, shows the calendar rule: November 27, 2026. What matters to shoppers is the price, and the 30-day median shows whether it already dropped before the date.

It depends on the model, and only the series can answer. The Radar saves the price of each power bank every day and compares today’s with the 30-day median: a price that rose in the previous days barely moves that median, because it uses the middle value of the series. The page for each power bank shows the history of of the power bank.

These are the popular names for a sale where the discount doesn’t hold up. The check is the same as on any day: compare today’s price with the same model’s history, not with the "was" price on the tag.

It saves the price of each model every day and compares today’s with the median of the last 30 days for the same power bank. It only counts as a confirmed drop with enough history (14 days or more of history) and 5% or more below the median.

179 models of 22 brands, from $9 to $200 in Nov 6, 2026. The price is that of the product in the catalog, as listed by the store; the final price is the store's.
