Revolt’s PB‑830 crank‑solar powerbank, launched in early July 2026, remained a focal point of the market. A July 12 review confirmed its 20 000 mAh capacity, 20 W USB‑C Power Delivery input, Quick Charge 3.0, Qi wireless charging, LED flashlight with SOS mode and compass, and noted a €39.99 price in Switzerland. The same test compared it with the Intenso HE25000, which led performance charts with a 90 Wh (60.8 Wh usable) pack and 140 W output, and the Ugreen Nexode 20 000 mAh model, praised for price‑performance at €39.99.

A July 17 article reiterated the PB‑830’s specs and paired the device with the EcoFlow Delta Pro powerstation, still highlighted as the top‑rated off‑grid solution (3 600 W continuous, 3 208 Wh usable). The Delta Pro’s multiple AC, USB‑A/C, DC, EV‑charging and CEE sockets underscored a trend toward high‑wattage, versatile emergency power.

In early August, Revolt expanded its lineup with the PB‑850, offering the same 20 000 mAh capacity but a higher 22.5 W total output, dual USB‑C Power Delivery, Quick‑Charge USB‑A, an 8‑pin Lightning connector and an LED display for multi‑device charging. Meanwhile, Metmaxx entered the segment with the SolarPowerBankEvo, a rugged 10 000 mAh solar‑rechargeable unit featuring built‑in panels, multiple input ports, a 5 W inductive pad and IP5 splash protection, highlighting continued diversification of portable energy solutions for outdoor and emergency use.
