Detailed Review

The listing states a 1.4W solar bird bath fountain with 8 nozzles and 4 brackets, 4-27.5 inch spray height, starting in 3 seconds in direct sun, at 6.3 x 6.3 x 0.63 inches.

Where the points went

The Solar Score weighs performance, build, value, safety and warranty. For a solar fountain, safety means the protection features the listing states, such as water shortage shut-off, anti-clogging or auto power-off; a listing that states none scores zero on that line. None of the five state a warranty term. How we pick explains the weights.

How to choose the best solar bird bath fountain with battery backup

Battery and runtime

Three state 2000mAh: the GAIZERL SP40B1 with 5-6 hours without sun, the Yzert with 4-6 hours after 2-3 hours of charging, and the GAIZERL AS10P1 with no runtime stated. The AISITIN states 1500mAh with a 34-hour claim that reads as odd for the capacity. The Mademax states no battery and no stored energy, so it stops without direct sun.

Fountain Stated battery Stated runtime
GAIZERL 3.5W Battery Fountain 2000mAh 5-6 hours
Yzert 3.5W Battery Fountain 2000mAh 4-6 hours
GAIZERL 3.5W Glass Fountain 2000mAh Not stated
AISITIN 3.5W Battery Fountain 1500mAh 34 hours (stated)
Mademax 1.4W Solar Fountain None Sun only

Nozzles and spray height

The Mademax states 8 nozzles with a 4-27.5 inch spray height, the Yzert and both GAIZERL state 7 nozzles, and the AISITIN title says 10 while its bullets say 6. The GAIZERL SP40B1 states 3 spray heights from 4-23 inches, and the Yzert states a normal height of 12-20 inches. For pump options, see our best solar water pump for fountain guide.

Protections and panels

The Yzert and GAIZERL SP40B1 state water shortage shut-off with anti-clogging, and the AISITIN states auto power-off. The Yzert and both GAIZERL state glass panels, while the Mademax is plastic. For battery-backed pumps, see our best solar water pump for water feature with battery backup guide.

The odd claims

The AISITIN states 34 hours of runtime from a 1500mAh battery, which reads as odd. The AISITIN title says 10 nozzles while its bullets say 6; the listing leaves the count unclear. The Mademax appears in a battery-backup roundup while stating it has no battery; this review flags it rather than scoring it up.

Sizing Notes

  • Check the battery: 2000mAh, 1500mAh, or none stated.
  • Check the runtime: 5-6 hours, 4-6 hours, or sun-only stated.
  • Match the nozzles: 8, 7, or 6 or 10 (unclear).
  • Check protections: water shortage and anti-clogging stated on two.
  • Check the warranty: none stated on any of the five.
