FlashFish TSP100 Solar Panel Review
A foldable 100W monocrystalline solar panel with 18V DC output for compatible power stations, plus built-in 65W USB-C PD and 18W USB-A outputs for direct device charging.
Is the FlashFish TSP100 worth buying?
Yes, if you own a FlashFish power station (or another 18V-compatible unit) and want off-grid recharging. The TSP100 is a 100W foldable monocrystalline panel with an 18V/5.6A DC output, plus its own 65W USB-C PD and 18W USB-A QC 3.0 ports so it can charge phones and laptops directly without a power station in between.
A foldable panel that also charges devices directly
The TSP100 (model TSP18V100W) is a foldable monocrystalline solar panel rated for 100W output, delivering 18V/5.6A DC power to compatible power stations. Unlike a purely pass-through panel, it also includes its own 65W USB-C PD port and an 18W USB-A QC 3.0 port, so you can charge a phone or laptop directly from the panel without a separate battery.
What makes the TSP100 stand out
100W monocrystalline cells, 18V DC
The panel is rated for 100W output at 18V/5.6A DC — enough to meaningfully recharge a mid-size power station like the T1200S over the course of a sunny day.
Built-in 65W USB-C PD and 18W USB-A
Beyond the DC output for power stations, the panel has its own 65W USB-C Power Delivery port and an 18W USB-A Quick Charge 3.0 port, letting you charge phones or laptops directly from the sun.
Foldable design, 2.8 kg
The panel folds down to 415 × 402 mm for transport and storage, unfolding to 1562.1 × 402 mm for full sun exposure, and weighs 2.8 kg.
12-month coverage
FlashFish backs the TSP100 with a 12-month warranty from date of purchase, matching the warranty period on its compatible power stations.
