Bests & Worsts Reviews from Amazon

I just wanted to post this because I had a really difficult time comparing the capacity of this battery to others, and thought this might help. This battery is labeled as having a 58830 mWh capacity, however almost every other power bank on the market measures capacity in mAh. I saw this had mostly positive reviews, so I bought it and wanted to test it out. The Halo battery only has 4 flashing light indicators to see how much charge it has. I decided to run a test using the Halo battery and a reliable 20,000 mAh battery I have that has the percentage charged listed in numbers. Starting with my 20,000 mAh battery fully drained, and the Halo bolt 58830 fully charged, I started charging my 20,000 mAh battery off of the Halo bolt. A few hours later, the Halo bolt was fully drained, and my 20,000 mAh battery was reading 49% charged. SOO, I arrived at the conclusion that the Halo Bolt 58830 has roughly a 10,000 mAh capacity. Which is actually disappointingly small given the fact that most 10,000 mAh power banks cost an average price of $20 on Amazon from any other seller: https://smile.amazon.com/s?k=10%2C000+mah+power+bank&sprefix=10%2C000+mah&ref=nb_sb_ss_i_1_10 Hope this helps! The one positive about the Halo Bolt is the 65V ac output, and the safety claim of jumping car batteries. However, with the 10,000 mAh capacity, you drain the bank QUICKLY using the 65V ac output. ✌️
