NATURBUMMLER 5200 mAh power bank, 200 h stated, 2200 K to 5700 K review

A stainless-and-bamboo lantern publishing an adjustable 2200 K to 5700 K colour range and 200 hours with no level, and no output figure in any unit.

The bottom line It publishes the colour of its light in kelvin and never publishes how much of it there is.

What this listing puts on record

A rechargeable camping lantern with a stainless steel housing and a bamboo base, stepless adjustment of both brightness and colour temperature, a 5200 mAh pack that charges a phone over USB-C, an integrated hook and a stated IPX4 rating.

The figures it publishes

2200 K to 5700 K, steplessly adjustable. It is one of only three colour statements in this hub, and it is the specification that decides whether a pitch looks like a fireside or a kitchen.

5200 mAh, with a power-bank output over the same USB-C port.

The figure with nothing attached

Up to 200 hours. No level, and no output anywhere in the listing to attach it to. The lantern dims steplessly, so the honest reading is the very bottom of the range — and how much light that is, the maker never says.

What else is missing

No output in lumens. No weight, on a steel-bodied lamp. No battery chemistry, on a sealed pack.

Before ordering

If you are choosing between this and the near-identical 5200 mAh, 200 hour, IPX4 lantern beside it in this hub, the kelvin range is the difference on the page.

Availability

Selling at about 31 € on the German Amazon store when this page was checked.

It also sells on the British Amazon store in the local currency, which the range above does not cover — that range counts euro stores and nothing else.

Nothing came back from the American, French, Italian and Spanish Amazon stores, so the buy link there opens a local search instead of a page that is not there.

Every figure in this section is what Keepa returned on the day this page was last updated. Prices and offers change without notice.

What it does well, and where it gives way

Strengths

  • Publishes an adjustable colour range from 2200 K to 5700 K, which is the specification that decides what an evening looks like
  • Brightness and colour temperature are both stepless, so the lamp is set rather than stepped
  • A stainless steel housing with a bamboo base, named materials rather than a generic robustness claim

Compromises

  • No output figure in any unit, so the colour range has no brightness attached to it
  • The 200 hours has no level, and on a steplessly dimmed lantern that makes it the least useful form of the number
  • A stainless steel body with no published weight, on a light sold for camping and walking

What people ask before buying

What does 2200 K actually look like?

It is the warm end — nearer a candle or a campfire than a bulb — and 5700 K is a cool daylight white. Publishing both ends and stating the adjustment is stepless tells you more about sitting under this lantern for an evening than a lumen headline would.

Why no weight for a steel lantern?

The listing does not give one, and stainless steel with a bamboo base is the construction where the question is most worth asking. Two lanterns in this hub publish a weight; this is not one of them.
