Hyper Tough 20V Max 4.0Ah USB A+C Lithium-Ion Battery Pack

Overall quality is good, but the one that I got, may have came from a bad batch. This doesn't normally happen, so I would still get this particular power inverter. The batteries that I got for it lived up to my standards, and did as I expected them to do. I am actually using one of the batteries to charge my phone right now.

i havent had great experience with these batteries but i give this a higher rating because of the 3 year warranty and I am hoping with these updates they've made, they've also improved the batteries retention. ive had alot of batteries die on me that say are fully charged but have no juice. otherwise it would be a 5-star for affordability, im hoping to be pleasantly surprised.

this battery, as well as the one that cone with the hyper tough weed wacker, take hours to charge! This doesn't work in this day and age if one is working on the clock! Come up with better batteries and I will gladly change my review. Your weed wacker is an excellent product, though.

Packing an impressive punch, this battery adapts seamlessly to various needs. It guarantees a robust performance with its long-lasting power reservoir. The dual USB ports add smooth versatility. Always knowing the charge remaining is a definite plus!

Efficiency is the name of the game here. This battery keeps all my tools alive and kicking. The light and compact design make it hassle-free to carry. Offering dual charging options, it's a game-changer. I'm grateful for the peace of mind it provides.

This little powerhouse keeps my tools running tirelessly. Both USB ports make charging super convenient, especially for multitasking. Knowing the battery level at a glance is incredibly reassuring. Perfect for demanding jobs and everyday tasks alike!

This thing works like a CHARM!! And it LASTS!!! While I still use my original charger to charge all my batteries, I do love the flexibility to charge this using my USB-C cord. And I absolutely love the power light indicators! No more having to guess how much battery is left when I'm using it!! I just press a button and it lets me know about how much I've got left!! I use them interchangeably for my trimmer, blower, and lawn mower and they work perfectly! These new batteries are amazing!!!

This battery pack channels reliability like no other. Consistently delivers extended power for diverse tasks. The life indicator is a handy feature to monitor usage effortlessly. Charging through dual ports is a breeze, making it an essential tool companion.

A dependable option to keep my tools powered. The compact size is appreciated for crowded workspaces, and the longevity of charge exceeded my expectations. The USB ports are a lovely bonus.

What a lifesaver! This powerhouse of a battery really keeps my tools running tirelessly. The charge level indicator is a thoughtful touch, keeping me informed without any guesswork. The multiple USB ports are a wonderful convenience.
