Frequently Asked Questions

Which is better for charging an EcoFlow DELTA Pro — VLAIAN or TPDEFZQ?

The TPDEFZQ is the better choice for the EcoFlow DELTA Pro because it outputs 36V, which matches the DELTA Pro’s preferred input voltage. The VLAIAN only puts out 18V, so you’d need to wire two panels in series to get the same voltage. The TPDEFZQ also includes an XT90 connector that works directly with EcoFlow’s DELTA Pro and DELTA Max units right out of the box.

Is the TPDEFZQ worth the extra cost over the VLAIAN?

In my testing, yes — the TPDEFZQ’s 25% efficiency versus the VLAIAN’s 23.5% means you get more power from the same sunlight, which adds up over a full day of charging. The TPDEFZQ also has a higher customer rating (3.9 stars from 32 reviews) compared to the VLAIAN (3.7 stars from 12 reviews), and it comes with a 12-month warranty. The VLAIAN’s main advantage is its IP68 waterproofing, but for most campers, the TPDEFZQ delivers better overall value.

Which panel is more portable for backpacking or car camping?

The VLAIAN is slightly more portable at 30.4 lbs with a folded size of 30.7×23.6×2.0 inches, compared to the TPDEFZQ at 31.2 lbs and 35.43×22.99×1.77 inches. Realistically, both are heavy for backpacking — I wouldn’t carry either one more than a few hundred yards. For car camping or RV trips, the weight difference is negligible, but the VLAIAN’s smaller folded footprint makes it easier to stow in tight spaces.

Can I use either panel with a Jackery Explorer 1000?

Yes, both panels work with the Jackery Explorer 1000, but they connect differently. The VLAIAN includes a dedicated DC7909 connector that plugs directly into Jackery’s input port, so no adapter is needed. The TPDEFZQ uses its 4-in-1 MC4 cable with an Anderson connector, which also works with Jackery units. Both panels will charge the Explorer 1000, but the TPDEFZQ’s 36V output will deliver power more efficiently on sunny days.

Which panel is more durable in rainy or dusty conditions?

The VLAIAN wins on durability with its IP68 rating, meaning it’s fully protected against dust ingress and can handle submersion in water. The TPDEFZQ is rated IP67, which is still excellent for rain and dust but can’t be fully submerged. Keep in mind the TPDEFZQ’s control box isn’t waterproof at all, so you’ll want to keep that part dry during a storm. If you camp in monsoons or near rivers, go with the VLAIAN.

Do these solar panels work with Bluetti AC200P and AC300 power stations?

Both panels are compatible, but the TPDEFZQ is the better match. The VLAIAN works with Bluetti AC200P and AC200MAX through its Anderson connector, but its 18V output means slower charging. The TPDEFZQ’s 36V output is closer to Bluetti’s optimal input range of 35-150V, so you’ll get faster charging speeds. For the Bluetti AC300, the TPDEFZQ’s XT90 connector is included, while the VLAIAN requires an adapter.
