V75

This V75 is the third Voltaic Battery pack that I have purchased. It feels solid, has a substantial amount of power and just the right ports. I liked this so much that I bought it a second time, which is saying a lot since I own nearly twenty assorted battery banks. I use them an a bunch of electric vests, to charge gear, not only phones but also camera batteries and to run cameras! These Voltaic's claim to be always on, and I believe that is a function - while often found in USB-C ports is not a native feature to other USB port types. This product performs better than most if not all other banks that I own in three ways: 1] With a high powered charger it charges VERY FAST! 2] The dimensions are very efficient to pack the greatest capacity in the most compact shape. 3] The always on feature for the USB A ports allows me to use it with intermittently operated devices that I may want to operate remotely with the power shutting off at the bank, making the device unresponsive. Just as or perhaps even more important that the hardware performance is the human force behind the product, and I was particularly impressed with the ease and professionalism that the company backed their product, and replaced a unit in which only one port became defective! These battery banks are without a doubt the best looking, and best feeling packs to have and hold and dealing with the company has been a pleasure.

It’s is an always on extra battery bank. I use this with a 9 V adapter for my electric lock for my door. It lasts forever. It’s a little expensive but it does what it says, and it doesn’t power off like most battery banks will not being used heavy duty quality metal body. It is what it is advertised I would buy more and I plan too soon.

Good battery pack. I needed one that was always on for a device that draws very little current. Some battery packs so the auto shut off if there is only a low current draw.

Expensive? Yes. Does it do what it says it does? Yes. I got this because my "Smart" door Lock from Yale runs on (4) AA batteries that die pretty quick because the front door is used a lot. I would come home to the door not auto locking because power is low or completely dead. I tried using a battery bank, but of course all the battery bank turns off once no power is detected or the power is too low. I've scoured the internet for tricks and fixes, but only this listing would solve my problem. I didn't want long wires going from the door to the outlet. That's too tacky. Got this and at first I thought it wasn't working because the LED would turn off, but that wasn't the case. The battery bank was still powering my smart door. HALLELUJAH! I've found my solution and pretty happy with the result.

bad battery, discharges quickly

Everything about this is exactly what I need to keep my phone charging- unlike the non-apple battery cases where I have to press the button on the battery case to keep it charging- this keeps my phone and battery case charging continuously. It could be used to charge a phone with or without a battery case. The way I see it- it’s an extension of the battery case- extra battery power- plus it creates the advantage similar to the older apple battery cases- it keeps charging and no need to press a button to get it charging again. Suits my needs perfectly. I’ll update if there are any issues. Quality product. Very simple to use.

works as advertised, successfully powers 5V microelectronics projects directly, without shutting down because it 'thinks' the typically low current draw is just leakage.

Unlike many power banks, this one does not stop providing power when a device only needs to sip little amounts of power. A "safety feature" of many power banks forces them to stop outputting power when they detect that the device plugged into them is fully charged or is only drawing tiny amounts of power. I needed to find a power bank that would continue to power devices that only draw tiny amounts of power. THIS IS THE ONE! It's perfect for this requirement. It also has another added benefit. It can be charged while it continues to power devices that are plugged into it. That's amazing for my application. (It can also be charged by a solar panel if necessary.) I'm now planning to buy at least two more for use in my projects that require this specialized power bank.
