How to get your first 100 customers for a premium portable solar power bank
To win your first 100 customers for a premium portable solar power bank, go where people already plan trips and outages around staying charged off-grid, not into broad ads. The highest-fit communities are r/CampingGear, r/overlanding and r/backpacking (where keeping devices powered for days is a real, recurring problem), preparedness and off-grid hubs like r/preppers and r/SolarDIY, and travel and EDC communities like r/onebag and r/EDC. Lead with proof — real charge times and panel output in the field, not marketing claims — and a founder with no audience can earn trust and orders for free.

They cluster in r/CampingGear, r/overlanding, r/backpacking and overlanding/van-life Facebook groups for trips; r/preppers for emergency power; r/SolarDIY for efficiency-minded buyers; and r/onebag and r/EDC for travel-carry. Discovery happens via TikTok/Reels outdoor creators and gear-review YouTube.

Lead with proof, not claims — real charge times and panel output in the field. Post honest tests in r/CampingGear, r/overlanding and r/SolarDIY, be genuinely helpful in van-life and off-grid Facebook groups, and seed units to outdoor creators and a solar-test YouTuber so demonstrated performance drives orders.
Do I need an ad budget?
No, though a crowdfunding campaign helps validate a premium product. The winning motion is evidence-led participation in outdoor and preparedness communities plus creator and reviewer seeding, not paid ads, for the first 100 units.
Since this ships online, where are the best buyers?
Because it's a DTC product shipped anywhere, focus on the highest-intent global communities — campers, overlanders, van-lifers and preppers — in subreddits, Facebook groups and on outdoor creator channels, rather than any single city.
