Review on 🔦 HUDAKWA Night Vision Goggles: Complete Darkness Binoculars with Wi-Fi and LCD Digital Infrared Technology - Perfect for Hunting, Security, Military, and Tactical with 32GB TF Card Included by Jill Ross

The downside to this is the battery issue. It does not use rechargeable internal battery, and it is said not to use rechargeable cells, otherwise it may crash the boot process. I may test this theory in the future, but for now I've been using new alkaline batteries. This worries me a little because I know something about battery characteristics. An alkaline kit operates at 1.5 volts, but after 25 percent of its life it drops to 1.2 volts and the supply voltage slowly continues to drop. Compare this to battery types that deliver 1.2 or 1.25 volts over their lifetime. If the electronics were designed here, they should be so efficient that only new alkaline batteries could be used. You should change the schemas to make them more flexible. Miniature electronics and new developments have always fascinated me. I persuaded my parents to buy me one of the first compact color LCD TVs when they came out. It was given to me at a restaurant for my birthday and I was dying to try it so I immediately put the batteries in. The batteries were new alkaline batteries, six AA sizes, as in this device. Back then there was local, non-digital broadcast, so I got out the antenna and watched Cheers while I ate at the table. Towards the end of the half-hour show, I realized something was wrong with the picture, then the TV went off. I put in new batteries late and everything was fine for about 45 minutes. While the compactness of the design was excellent for a very compact color TV, the electronics were so delicate that simply turning off the first 20 percent of the power reduced the voltage so much that the TV could no longer function. I received a purchase receipt and returned the TV for a refund. I'm not sure if that's the case, but the requirement for new alkaline batteries suggests that might be the case here. This device requires a built-in lithium battery. Something the manufacturer needs to be aware of. All that says it's a good device with good features. In 1992 he bought "Russian Surplus" night vision binoculars for 650.00. During the day it didn't work and at night everything was green. Considering the price I paid I was disappointed and sent it back. Here we have something in less than half that works in daylight in color, takes photos, has multiple resolutions and connects to a phone or tablet via WiFi and has a memory card slot, plus there was a card for 32 gigabytes. The instruction manual is pretty decent and you'll need it to figure out how to use the six control buttons on the device. Very nice HD color screen with an easy to use menu system. Digital zoom up to 4x and external focusing on the lens. At first glance I wanted to at least look from the other side, but I wasn't. It also includes an IR light source for night vision. Night vision isn't color but thankfully not green, each spooky gray and white image makes it easy to spot animals and other objects in the dark. I would definitely give five stars if it was rechargeable. Robust, handy device. Collar to wear while walking, lift up or look down. Takes beautiful photos and videos. I was able to transfer them to my laptop via USB and cable for viewing. highlighted.
