Do Power Banks Lose Charge

I use these for some of my old power banks because most of my devices have USB-C now. This lets me charge some low power (non-USB-PD) devices more easily. It's very compact so it does not put much strain on the ports. For data transfer, an active USB-3 capable adapter is better.

[This review was collected as part of a promotion.] This power bank is awesome. It is lighter than other power banks I have owned and is sleeker. The fast charge feature is really convenient and cuts out a lot of charge time. Would definitely recommend this power bank over any of the other big name branded ones I have used before.

[This review was collected as part of a promotion.] I had stopped using power banks because I could never get a good charge off of them. I am really impressed with this Belkin Boostcharge Power Bank 10K. Not only do I get a good charge, it's fast and the charge I get from it lasts! I like the added 2 USB-A ports and one USB-C port that allow me to charge my IPad and MacBook at the same time too. It will be convenient to throw in my backpack for hiking this Summer. My wife saw it, and now she wants one so I plan to order her one too!

I have three of these now and they all work as advertised. I use them both to QC charge phones and to PD power charge power banks and these work nicely in each application. They are fairly light and the folding plug prongs are very handy.

Short, perfect for use with power banks that you want to hold both in one hand!

We love our power banks. It’s small and convenient for our pockets.

Purchased for backup in case we lose power temporarily. This arrived well boxed, the instructions to charge and setup a clear. Hope I don’t need it, but I live in one of the top states for power outages and would rather have some security. I plan to add something bigger for larger appliances, but for now phones, laptops and our router are good to have covered in case of power out.

Great clamp for portable power banks. Love the quality of the spring!

Works as advertised...charges quick and lasts a long time. I'm always looking for small power banks to fit in my camera bag and this one is perfect. Light weight and gets the job done. Great for the kids' Switches in the RV too. The only drawback is that you have to remember to turn it on. My other power banks (under 10,000mAH) automatically power on when they are plugged in. No biggie though, me and the kids caught on quick. I highly recommend this product.

after many years it still works.........we often lose power
