Detailed Review
The Luvknit is the weight pick: 20000mAh at 0.52 lbs in a 5.63 by 2.91 by 0.85 in body with an IP65 rating for rain and dust.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. Safety here means stated certifications and codes: IP65 and UL1778 on the wongkuo, CE, FCC and RoHS on the Durecopow, and nothing stated on the three title-only banks. Warranty goes to the wongkuo at 2 years and the Durecopow at 12 months; the rest state no term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |

| Durecopow 49800mAh Bank | 9.6 | 29 | 20 | 20 | 6 | 1 |
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.
