Display

Neither product has a display in the traditional sense, so there is no screen quality winner here. What matters instead is how clearly each product communicates its output and charging status through the connected device or power station. On that front, the GRECELL is more likely to be paired with a power station that shows live wattage, input voltage, and charging progress, which is far more useful than a simple phone charge indicator. Winner: GRECELL, because its intended ecosystem gives you better visibility into real solar performance.

Performance

This is the biggest difference by far. The GRECELL panel is rated at 100W and 20V, which puts it in a completely different class from the 30W Anker Solix PS30. In practical terms, the GRECELL can meaningfully recharge a portable power station, support longer off-grid use, and feed larger batteries with usable solar input. The Anker PS30 is better described as a small-device charger: it can top up phones, earbuds, and maybe a compact power bank, but it will be slow and limited for anything more demanding. If you want to keep a camping battery station alive, the GRECELL wins decisively. Winner: GRECELL.

Build quality and design

Anker usually has the edge on fit, finish, and user-friendly design, and the PS30’s IP65 water and dust resistance is a strong practical feature for UK weather, damp campsites, and beach use. Its 30W output also means it can be lighter and easier to carry, which suits hikers and day-trippers. GRECELL’s 100W foldable panel is more ambitious and likely bulkier, but that is the trade-off for real output. The GRECELL’s design is purpose-built for power station charging rather than casual phone charging, so while Anker probably feels neater and more polished, the GRECELL’s design is more functional for its job. Winner: Anker, for portability and weather resistance; but only for smaller-scale use.

Battery life

Strictly speaking, neither product has an internal battery, so battery life depends on what you connect them to. The GRECELL is the clear winner because it can replenish a power station or larger battery much faster and more usefully than a 30W panel. For example, a 100W panel can make a real dent in a 300Wh to 500Wh power station on a decent sunny day, while a 30W panel is mainly for slow trickle charging. If your goal is to extend runtime rather than just maintain a phone charge, the GRECELL gives you far more usable solar energy. Winner: GRECELL.

Price and value for money

The Anker Solix PS30 costs £39, while the GRECELL costs £129.99, a difference of £90.99. That makes the Anker the obvious value winner on upfront cost, especially if you only need a lightweight emergency charger for a phone or small battery pack. However, value is not the same as cheapest price. The GRECELL’s much higher wattage means you are paying for actual capability, not just portability. If you already own a power station or plan to buy one, the GRECELL is better value in terms of watts delivered per pound for serious use. If you only need occasional top-ups, the Anker is better value because you are not overpaying for power you will never use. Winner: Anker for budget buyers; GRECELL for power-per-pound.

Game library/features

This category does not apply in the usual sense, but the equivalent is feature set and charging versatility. The Anker PS30’s standout feature is its ability to charge two devices at once, plus IP65 resistance, which makes it highly convenient for everyday outdoor charging. The GRECELL’s standout feature is its 100W output and compatibility with power stations, which is a much more important feature if you care about off-grid energy independence. In other words, Anker wins on convenience features, while GRECELL wins on serious solar capability. Winner: tie, depending on whether you value convenience or capacity.

Overall user experience

The Anker Solix PS30 is the easier, friendlier product for casual users. It is cheaper, simpler, and better suited to people who want a foldable solar panel for phones, small gadgets, and occasional outdoor use. The GRECELL is the better buy for anyone who actually wants to generate meaningful solar power, especially for a portable power station, camping fridge, or multi-day off-grid setup. The user experience difference comes down to intent: Anker feels like a handy accessory, while GRECELL feels like part of a real energy system. Winner: GRECELL for serious users, Anker for casual users.

Overall summary: if you want a proper solar charging solution that can feed a power station and deliver real utility, the GRECELL 100W panel is the clear winner. If you want the cheapest, lightest, most convenient panel for phones and small devices, the Anker Solix PS30 is the smarter buy. For most people comparing these two directly, the GRECELL is the more capable product, but the Anker is the better budget pick.
