Portable 4X Aa Battery Usb Power Bank Charger

I was asked by Coast to review the ZX AA battery as a field tester. Coast sent me a package that contained 4 AA batteries as well as a charger. The instructions advised to charge the batteries prior to using. The charger is capable of charging 1-4 batteries at a time. The batteries have a USB-C charging slot so it was easy to connect the charger and start that process. The power source end of the charger cleverly is able to be plugged into a USB-A or USB-C adapter. The batteries were fully "recharged" in about 20 minutes. There is an indicator light on each battery for the status of the charging process. I tested 2 batteries in one of my many Coast flashlights. The batteries provided power for just over 4 hours before needing to be recharged. There was no change in brightness of light while the flashlight was on. The recharging process took about 30 minutes. If you are looking for AA rechargeable batteries, these are a nice choice!

Excellent portable power bank.

[This review was collected as part of a promotion.] I was so excited to try the Belkin BoostCharge Hybrid Wall Charger 25W + Power Bank 5K. This 2-in-1 gadget is like a little superhero for your devices. This thing rocks! It can be a wall charger at home and a portable power bank when you're out. There is no need to carry separate chargers anymore. The 25W USB-C PD port delivers fast charging, which is a lifesaver when you're short on time. While it goes down to 20W in power bank mode, it's still plenty quick for a quick top-up. With both a USB-C and a USB-A port, you can charge two devices at once. Perfect for keeping your phone and a friend's device juiced up. While the charger itself is great, it doesn't come with a cable. This means you'll need to have your own on hand.

Phantom power only-- no AA battery.

I have two of these chargers. They are well built and powerful. However, that power comes with a string attached - if you want to rapidly charge a Mavic 3 battery the input voltage has to be greater than produced by a typical full charged 12 volt battery. DJI tells us this - stating that we should use the charger only with the car running. However, the specifications state that the input voltage needs to be 12.7 - 16 volts DC. Which led me to assume the 540 amp hour 12 volt battery bank in our expedition truck, which delivers 12.8 - 12.9 volts when fully charged would be sufficient. That is not the case - I need to have somewhere between 13.1 and 14,1 volts minimum (closer to 14.1 I suspect) for the rapid charger to work with an Mavic 3 battery. I can work with that as long as I charge during the day with solar input raising the voltage of the battery bank or when the truck's engine is running. This charger will work fine charging a Mavic Mini 2 battery bank with the supply at 12.8 (perhaps lower as well - I've not tried that). It might also charge the Mavic 3 battery via the USB 2 - USB 3 outlet but at 10 watts I'd presume that would considerably slower than the 65 watts possible with USB 3 - USB 3 outlet. I have not tried my car chargers with large portable power banks like those from Goal Zero or Jackery. I suspect the same restraints would apply - rapid USB 3 to USB 3 of a Mavic 3 battery will require solar or other supplemental input. Again - not a problem if you plan for that. I've given the charger 5 stars because it is great and works well as long as one respects the design parameters.

I've been using this as a multi-purpose unit from camera battery to portable power bank for recharging my phone and other USB devices. It's quite compact for 98Wh and pretty great price too.

Great for charging your Nikon camera battery when you have to charge in the car or from a power bank. The charger provides a lot of useful information during the charging process, and is very compact. I am impressed with the functionality in this unit - why can't the camera manufacturers take a look and learn.

I have a four bank swittronix vmount charger and this is way more portable, comparable to the redcharger.
