## Customer Reviews

### ⭐⭐⭐⭐⭐ Great 5V battery
*by J***Y on November 21, 2024*

the solar battery on my Allen + Roth umbrella from Lowes broke (My fault). I missed having the LED lighting at night. I bout this to see if it would work... low and behold... works like a champ. I don't know how long it lasts, but at least a few hours. I have never stayed awake long enough to see when it dies. Great way to fix/save an $500 umbrella.

### ⭐ Poor regulation
*by C***Y on February 26, 2025*

I purchased 2 5v 4A battery packs. They each have different issues.The first pack worked fine until the output was 0v. The charger shows it is fully charged, but there are 0v at the outputThe second pack seems to have a correct output of 5v, but even a small load (less than 3A) sends the voltage to 0. It can't support much of a load at all

### ⭐⭐⭐⭐⭐ Works like a champ to power a Loco Griddle
*by J***K on April 13, 2025*

I use this batter to power a Loco Griddle. I use a magnetic dry erase marker holder to hang it on the side of the griddle.
