    What I need to know cuz I just bought one in them out in the woods camping in a tent with an e-bike how do you adjust the cooler cuz there's two zones and I can't figure it out it keeps going from 48 degrees to 38 degrees. I think one is for each side and I don't know how to adjust it I hate reading directions but maybe I have to LOL I thought there was a video cuz it's much easier to figure it out then these can save you so much freaking money on ice it will save you if you're camping everyday about 150 bucks a month like saving money don't you?

    I think any charger with qc should be avoided unless it has been tested well and deeply since there's always a voltage issue with them and they terminate early when charging or some other problem. A charger with 12V supply is the way to go or it can have 5v supply without qc support but it will be slow because no manufacturer designs a charger considering it will be used with high power 5V power supply.

    Names self "Expert": 1. Does not even read the manual. 2. Charger clearly indicates NiMh batteries, puts Ni Cd anyway also gripes about it not supporting lithium batteries. 3. Charger clearly only fits AAA and AA batteries, brings out a D battery "for comparison". 4. Charger clearly indicates 5V 2.1A power requirement, brings out a power bank without checking max output of said power bank. Wonders why it does not work properly and resets a lot, duh. 5. Puts in "good" batteries, but resistance reading clearly indicates 999ohms. Please read the manual and actually use the charger before making any video so you don't come out sounding ignorant.

      @oleggritsev 2 ปีที่แล้ว

      In fact, the charging process for both types of batteries is the same, no device wich can determine which type of battery is. Nickel-cadmium ones have a memory effect and are more demanding of charge currents, but still everything works exactly the same. I don't see any difference between these two types of batteries. just nickel metal hydride came to replace and they are newer in technology.

    This is a great Counter. The GM Tube is a J705 this has a 3-4mm big glass field that is reacting not a 5cm long tube 😅 this is why its for higher radiation. You should buy a BR-6 for that Video. The Humidty and temp is from your hand. The sensor is way more accurate than those house termometers. So your review is definitely wrong and should be corrected. You should have read de description from 3001 Counter. Then you would all know that...

    It's not a defect. I have the same set and have another set as well. They're trying to cheat. If you time it and watch the output on a scope you can see it ramp down. It draws >5amps at the start, then ramps down to about half an amp. Batteries inside are two 2000mAh cells in parallel, so the capacity isn't a lie. The claim of lumens/time is just total BS on the box. Shame on them.

      Actually some of products from costco have less quality if you buy it from original seller. Like this device form FEIT have grteen package. From costco - Orange.Manufacturers make goods for costco that are cheaper and save more because costco order contract for purchase price lower than other stores buy and they work with large volumes. So the goods are usually made for costco separately and have a lower quality so that the final price is lower.
