A dead phone at dusk on a trek, with the next outlet a day away, is the moment that decides this choice. On 5000mah vs 20000mah solar power bank packs, pick the 5000mAh side when a light pocket pack and 1 emergency charge will do, and pick the 20000mAh side when devices need charging across days off the grid. We compared 4 packs on capacity, solar charging, output and warranty.

We copied each rating from the seller’s listing as the brand states it; data date 8 November 2026.
Capacity and weight
Capacity is the split the listings state most clearly. The 20000mAh BLAVOR pair lists 4.2 charges for iPhone 15 on the purple listing and 4 charges for iPhone 17 on the green listing. The 5000mAh PRAANA lists 1 full emergency phone charge, and each Miady pack holds 5000mAh at 18.5Wh. On weight, the PRAANA is listed at 0.44 lb and each Miady pack at 4.2 Oz.
Solar charging
Solar charging is where the sides part ways. The PRAANA lists a 7W solar panel and recharging in 3 hours of direct sun, or via USB-C. The BLAVOR pair calls itself a solar power bank but states no panel watt figure, so solar recharge speed stays unclear on the 20000mAh side. The Miady listing states no solar panel at all, so it recharges only through its USB-C port.
Output and device count
Output favours the 20000mAh side. The BLAVOR pair lists 20W USB-C fast charging, 4 built-in cables, 3 charging ports and charging for up to 6 devices at once, plus wireless charging for phones and Apple Watch. The Miady 2-pack lists 12W output at 5V/2.4A, with 2 ports charging 2 devices at the same time. The PRAANA lists a USB-C battery with no output watt figure stated.
What the listings leave unclear
The purple and green BLAVOR listings share model PN-W39. Their phone charge counts differ, with 4.2 charges for iPhone 15 on the purple listing and 4 charges for iPhone 17 on the green listing. The Miady dimension figures differ between the bullets and the spec table; the bullets are the figure to use. Neither BLAVOR listing states a solar panel watt figure, and the PRAANA listing states no USB-C output watt figure.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For solar power banks, safety means stated protection against overcharge, over-discharge, over-current and short circuits. All 4 state a warranty term, from 1 year to 3 years, with the Miady at 18 months. How we pick explains the weights.

How to choose the best 5000mah vs 20000mah solar power bank
Match capacity to the trip
Count the charges the trip needs. The BLAVOR pair lists 4.2 charges for iPhone 15 on the purple listing and 4 charges for iPhone 17 on the green listing. The PRAANA lists 1 full emergency phone charge, so it suits a light top-up rather than a run of charges. See the best solar power bank for trekking for packs sized for the trail.
Check the solar panel figure
A stated panel watt figure is the only solar number that can be compared. The PRAANA states a 7W panel with recharging in 3 hours of direct sun. The BLAVOR pair states no panel watt figure, and the Miady states no panel at all.
Count cables and ports
The BLAVOR pair carries 4 built-in cables and 3 charging ports for up to 6 devices at once, with wireless charging for phones and Apple Watch. The Miady 2-pack carries 2 ports per pack. For charging devices at once, see the best solar power bank for multiple devices.
