Power-Bank-Portable-Charger - 40000mAh Power Bank QC 4.0 and PD 30W Quick Charging Built-in LED Display 2 USB 1Type-C Output Compatible with Most Electronic Devices on The Market(Starry Black)

This power bank comes with a whopping 40000mAh capacity - ensuring ample power for multiple device charges. Great for keeping our MacBook battery topped up during travel. Plus, the battery percentage display is a handy feature.A couple of things to keep in mind - It’s slightly larger than other batteries and we've found that recharging overnight works best because of the time it takes to get back to full.Overall, it strikes a nice balance between capacity and convenience. It’s a solid choice for staying powered up on the go!

It really does the work, the battery lives several days.It is a little heavy to carry around and takes time to charge it.

If you are not worried about actually carrying this with you for distances on foot, then this could be right charger for you. I bought it for a 3 day event and several people were able to bring their various devices to at least 30% charge in 15-20 minutes. And it still had 50% charge when I got home! Amazing power, and amazing power storage. Not sure about it long term, but I've used it randomly just to keep the battery fresh and it seems to be able to fully charge at least 5 or 6 devices from zero on a single charge. When I check it between charges, It never goes below 98% so it holds a charge for a long time between uses too.

Portable-Charger-Power-Bank - 40000mAh Power Bank PD 30W and QC 4.0 Quick Charging.. Lasts weeks before a recharge, use it to power my bluetooth speaker, will run it for 4 to 6 hours, 4 days a week, will easily go two weeks before i have to recharge. And the light if needed is super bright! Fast charging the power bank works great with fast charging base charger, though the power bank will not charge phone at a fast charging rate! But still a great charger/power bank.. Will totally buy another if needed! It is heavy for being such a small package, seems as if its because of all the batteries inside ;-)

i use this thing all the time when i am at work! Can recharge it pretty quick. Also we are about to fully charge 3 phones off this from being pretty much dead. love it
