More reasonably priced than other suppliers. Kids loved it ! Thanks Amazon ### ⭐⭐⭐⭐⭐ How to get around the solar charging. *by S***D on June 23, 2026* Hah, this is funny. I have a Macine 1000w battery that can't be charged by a mere 50w solar panel, So I charge my ReXHAM 300 w battery up via a 50w solar panel and then plug the big battery in whilst it's still charging from the sun.. It charges about 20/30% an hour. Yes, it would be better to buy a 100w solar panel to directly charge the Maschine but this is a way around if you only have a small panel. Hope tis helps. Charge your small bettery via solar and then use it to charge the big one. ## Frequently Bought Together - Iron Filings for Science, Education, Experiments, Students, and Teachers - 80g - Magnet Educational Long Alnico Bar Magnet Small with North South Identified for Students Teachers Science Education 2Pcs - Traditional Alnico Horseshoe Magnet for Science, Education, Experiments, Students, and Teachers - 1kg Pull - 75mm x 39mm x 8mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/725247694-magnet-expert-iron-filings-80g-0-17-lbs-science-education](https://www.desertcart.jp/products/725247694-magnet-expert-iron-filings-80g-0-17-lbs-science-education) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-15*
