The TSR 1 series from Tracopower are non isolated step down switching regulators in SIP package. These DC to DC converters are drop-in replacement for inefficient 78xx linear regulators. A high efficiency up to 96% allows full load operation up to 60�C ambient temperature without need of any heat sink or forced cooling. The TSR 1 switching regulators provide many significant features over linear regulators, such as better output accuracy (�2%), lower standby current of 2mA and no requirement of external capacitors. The high efficiency and low standby power consumption makes these regulators an ideal solution for many battery powered applications.

Okay
I like that it fits my umbrella well, hinges open for easy application and removal, and that it has enough light for us to see our food at night.
I do not like that half of the outer lights do not work part of the time until I take out the batteries and swap them around.
Fine enough for the price, not worth the hassle of returning.

Easy to use.
Works well. Light is bright. Our new patio umbrella does not have e a center pole, so the lights get somewhat blocked. But still pretty useful.

Sturdy & easy to move around
Its solid & sturdy. It does exactly what it’s supposed to. You have the option to fill it up with water or sand , I choose water. It holds the umbrella in place. The wheels and handle make it really easy to move around, which is a huge plus. It fits perfectly and feels very well made. Great addition for my pool area!

Heavy-Duty Base with Convenient Mobility
This umbrella base does exactly what it’s supposed to—keeps the umbrella stable while still being easy to move around when needed. Once filled with water/sand, it feels solid and secure even on slightly windy days, which gives peace of mind.
The built-in wheels are a standout feature. Moving the base across the patio is smooth and doesn’t require much effort. The handle placement is well thought out, making repositioning quick and hassle-free.
Overall, it’s a great balance of stability and convenience. Highly recommend if you want a sturdy base without sacrificing mobility.
