Affiliate disclosure

Nineteen Lab is reader-supported. Some links on this site are affiliate links — if you click one and make a purchase, we may earn a commission from the retailer or brand at no additional cost to you.

We participate in affiliate programs including (but not limited to) the Amazon Associates program and brand-direct programs run by manufacturers of portable power products. As an Amazon Associate we earn from qualifying purchases.

What this means for our reviews

• Commission rates never determine our rankings or picks.
• Brands cannot pay for coverage and never review our conclusions before publication.
• When we recommend against a popular product, we lose money on it. We do it anyway.
