How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For solar power banks, safety means the certifications, weather sealing and circuit protections the listing actually states. Three of the five state a 12-month warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| SOARAISE 48000mAh Bank | 9.7 | 32 | 21 | 21 | 5 | 3 |
| GULLVEN 49800mAh Bank | 9.7 | 33 | 22 | 21 | 9 | 0 |
| Nuynix 49800mAh Bank | 9.6 | 30 | 20 | 21 | 4 | 3 |
| YELOMIN S1008D Bank | 9.6 | 27 | 20 | 20 | 6 | 3 |
| YELOMIN PS36K Bank | 9.6 | 29 | 21 | 20 | 7 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best solar power bank for bikepacking
Count milliamp-hours against your devices
Capacity is the headline number here: 49800mAh on the Nuynix and GULLVEN, 48000mAh on the SOARAISE, and 38800mAh on both YELOMINs. Do not convert these figures into anything else; the listings state milliamp-hours at 3.7 or 5 volts, and that is the number to compare. One caution travels with the biggest brick: the GULLVEN listing warns its capacity may exceed airline carry-on restrictions, so check with the airline before flying. See our best solar charger for backpacking guide for lighter options.
Treat the panel as a backup, not the plan
Every listing here is honest that wall charging comes first and solar comes second. YELOMIN says solar is better for emergency top-ups, and GULLVEN says solar charging is relatively slow. The four-panel designs claim to close the gap:
| Power bank | Capacity | Solar panels | Maker’s solar claim |
|---|---|---|---|
| SOARAISE 48000mAh Bank | 48000mAh | 4 panels | Up to 5 times faster than single-panel chargers |
| GULLVEN 49800mAh Bank | 49800mAh | 4 foldable panels | 8 times the efficiency, 1280mA maximum current |
| Nuynix 49800mAh Bank | 49800mAh | Not stated | Solar as supplemental backup |
| YELOMIN S1008D Bank | 38800mAh | Not stated | Solar for emergency top-ups |
| YELOMIN PS36K Bank | 38800mAh | Not stated | Solar as emergency backup |
Read the multiplier claims as the maker’s marketing, and charge by USB before you roll out. See our best solar panel for backpacking guide if you want a dedicated panel instead.
Demand the ruggedness the trail needs
A power bank on a bike lives in dust, rain and vibration. The YELOMIN PS36K and the GULLVEN state IP65-rated dustproof, shockproof and water-resistant builds, and the SOARAISE and Nuynix state water-resistant, dustproof, shockproof or impact-resistant housings without an IP code. The GULLVEN adds a silicone port cover and drop-proof corners, and three of the five include a carabiner for hanging the bank in the sun. Every pick includes an LED flashlight with SOS and strobe modes. For more backcountry gear see our best solar charger for backcountry guide.
Read the warranty and the contradictions
Three listings state a clear 12-month warranty: the SOARAISE, the Nuynix and the YELOMIN S1008D. The GULLVEN warranty field reads “1” with no unit, and the YELOMIN PS36K warranty field describes a partnership with no term, so neither counts as a stated term. The contradictions: the Nuynix spec table lists the power source as Corded Electric even though the title and bullets describe solar and USB dual charging, and the SOARAISE spec table lists 2 ports against the 3 ports and 7 devices in the bullets. Trust the title and bullets both times.
Sizing Notes
- Match capacity to the devices: 49800mAh for phones, tablets and GPS across several days versus 38800mAh for shorter trips.
- Check the fast-charging wattage against your phone: 22.5W USB-C on the YELOMIN PS36K and GULLVEN, 15W on the Nuynix.
- Count outputs against your kit: 4 built-in cables on the SOARAISE, GULLVEN and YELOMIN PS36K versus 3 ports on the YELOMIN S1008D.
- Read the ruggedness against the trail: IP65 on two picks, water, dust and shock resistance stated on the rest.
