Solar power.
Pay as you go.
Stablray is a solar charging kit with NFC top-up. 60Wh storage, 20W solar input — and a simple card tap to keep the power on.
How NFC top-up works
Every Stablray kit comes with an NFC card. Top up online, then tap the card on the device to activate your time.
Top up online
Visit the top-up page, select an amount ($1.5 for a week, $5 for a month), and pay with Binance USDT.
Tap your NFC card
Once payment is confirmed, tap your NFC card on an Android phone with Chrome to sync the top-up data.
Tap the device
Tap the same card on your Stablray device. It reads the top-up and keeps running for the paid period.
