Trickle charging and fast charging are two different methods of charging batteries, and they vary in terms of the speed at which they charge a battery and the purpose they serve:
  1. Trickle Charging: Trickle charging is a slow and continuous charging process designed to maintain a fully charged battery without overcharging it. It is typically used for lead-acid batteries (like those in cars) and some types of rechargeable batteries (e.g., nickel-cadmium or nickel-metal hydride) that are sensitive to overcharging. Trickle charging supplies a low and constant current to the battery, compensating for self-discharge and ensuring the battery remains fully charged. It is a method used for long-term battery maintenance, such as keeping a car battery charged during storage or maintaining the charge on certain types of backup batteries.
  2. Fast Charging: Fast charging, as the name suggests, is a much faster method of charging batteries and is designed to quickly replenish a battery's charge. It is commonly used in smartphones, electric vehicles (EVs), and other modern devices where users want a rapid recharge. Fast charging involves delivering a higher current and voltage to the battery, enabling it to charge at a much faster rate compared to trickle charging. Different technologies like Qualcomm Quick Charge, USB Power Delivery (PD), and various proprietary methods are used to implement fast charging in devices. While fast charging is convenient, it may generate more heat and potentially reduce the long-term lifespan of the battery if not managed properly.

Small and Convenient

Great quality and super small with dual USB ports. Can pretty much fit anywhere and has an indicator light which allows you to know it is charging and in what mode it is in. Both ports can handle 40w, instead of just one being able to have that out put. All the technical outputs are conveniently printed on the back. The plug folds into it and slightly pokes out from the body which makes it easier to access. Minimal concern of it scratching other items due to it not being completely flush.Both ports are USB C, which is a slight downside due to not having a USB A but that is minimal as most things are C nowadays. The only other downside is the large logo on it, I would prefer it be along the side or smaller but that is purely personal preference. In the end it has found a permanent home in my electronics travel bag, along with its bigger version.

Great for devices that don't let you know when they're fully charged.

At first I thought the LED light was to show that the adapter was connected to power. But, it also tells when the device you are charging is fully charged. A blue light means that the device is still being charged. A green light means that all devices connected are fully charged, or are being trickle-charged. I attached an image of the adapter charging a set of bluetooth earbuds. Here you can see that the light is green while the earbuds are being trickle-charged with 0.06 amps at 5.2 volts.I also like that you can charge two devices at once at 20W each. I have encountered no issues in the couple of weeks I've been using the charger. I feel that the LED light sets this apart from most of the other chargers out there. Recommended.

Super compact dual charger!

Having a few phones, now all USB-C, having this take up just one outlet but allow for max charging for both my phones (iPhone 15 Pro Max, Pixel phone). I have used USB-C chargers that say they're fast charging, but my Pixel phone will just say "Charging", not "Charging Rapidly", and this one does it with one cabel, or if both are connected still. Frees up space on the wall outlets, love it!

very handy adapter

This will be nice for travel because the prongs fold into the body when not being used tho' I have in installed in an a/c power strip behind my monitors for now. The illumination showing when power is present is useful.Not much more to add. Looks and feels like a good product. Provides the rated power as best I can tell.

Perfect

This was perfect to use behind my nightstand. The top USBC ports allowed the cables to exit out the top or bottom of the adapter which protects the cords from damage and allows the nightstand to be placed all the way against the wall. The dual ports allowed me to connect two cables for my bedside safe and another for the phone charger. What a great little, well thought out device that is worth every penny.

Great compact adapter for your laptop (or other devices)

Love love love this little adapter. I needed something small to plug into a peculiarly-placed outlet in my room, but still have enough capacity for my MacBook Pro. This worked perfectly! For such a tiny thing, it packs a powerful punch. It charges my MacBook and iPad quickly (I would almost dare say quicker than the original large adapters they came with, but I never actually timed them against each other). The light indicators are a nice addition, letting me know if they're in "rapid-charge mode" or just "regular charge mode". Either way, it's a little adapter that does a great job.

Awesome little charger!

I like slim charges, so I was excited to get this UPTab 40 watt dual USB C charger!To test the charger, I drained a couple of my large USB batteries, then ran the charging cables through two USB power meters so I could verify the stated output. I let the setup run while watching the temperature of the charger.I like to run these tests for a couple of hours. I kept this test going though because I was concerned with how hot the charger was getting. After a little over 2 hours, the hottest temperature I could find on the case was 163.9 degrees. I fully expected to be giving this little charger one star!Shortly thereafter I saw the temperature start dropping while the charger was able to maintain most of its output. I can confirm thermal regulation works.After three hours, the hottest temperature I could find on the charger was 143.2 degrees.Awesome little charger, just be mindful that it will get hot if you are pushing it.

Good USB Block!

This USB-C wall block from UPTab works great and does a good job with charging 2 devices at the same time and supporting fast charging! Currently, I am using this to charge 2 rechargeable light bulbs and other accessories and so far so good! Nothing really special as this comes packaged basic and does include a manual though who would need that as it's basically plug n go! Does what it should and no complaints yet!

Nice little charger!

This dual USB-C fast charge block is really slim and perfect for travel! Each USB-C port is max out at 20W each, so it fast charges any device quickly. I like the portability due to the size and the charging prongs are folded into the body. This little charger is perfect for trips and can be carried anywhere. I would recommend this charger!

Pleased! Passed Tests.

I am pleased with this little charger and it has passed my tests and I expect it to be a regular part of my charging duties.The unit definitely PULLS 20-21 watts from the wall (according to my Watt meter) and is currently outputting 18.34 watts @ 12 volts charging a battery pack. It does that with temperatures < 90 degrees F which instills confidence for me.I've also tested it on my Pixel 7 which was 80% charged and it indicated that it was "Charging rapidly". Values showed 10.30 watts @ 9 volts which seems correct given how close it is to completely charged.I see no "red flags" for this device and am confident to use it daily.

Dual USB C charger that works as it should

This dual port USB C charger is of good quality and the size isn't so large that it covers up two plugs on an outlet. It will "Super Fast" charge a Samsung S22 phone if it is the only device being charged. If another device, in my case a Samsung S8 tablet, is plugged in at the same time, then the charging speed of the S22 will drop. This isn't a defect in the product, rather it is just a limitation of this or similar devices in total power output. Both devices will charge at an acceptable rate, just not at the top rate at the same time. This seems to be a well constructed unit that isn't overly large. I like that the unit has two of the newer USB C ports and that the wires connect either through the top or bottom of the unit (depending on charger placement). There is really nothing to dislike about the charger so it is recommended.

Very compact fast charger

This charger can fast charge your phone at 40W if your phone is capable of charging at that high rate or it can fast charge two phones at a time, splitting 40W between them. If you like small compact things this will make you smile.

Fast and easy to carry

This is the only brick I bring to the office and when traveling. Very compact and has two ports that charge my phone and Airpods super fast. I haven't compared the charging speed side by side to my older charger, but this one seems to be much faster.

Works perfectly

We use this UPTab 40W Dual USB C Charger Block everyday. It's a great space saver and it has two separate ports. Whenever I put my phone on charge with this block it always says fast charging and it does charge quickly. Its a great block to have for emergencies or as a spare or just to have an extra one with you this block will take care of your charging needs. I highly recommend this one.

Nice and small, travel ready

I like the flexibility of having 2 ports available. It’s a huge bonus that this charger is so small. It is the smallest I have yet and I’ve tried out several. I think it’s a nice feature to have the ports go down or up rather than straight out - when using in a wall outlet especially. I think it’s small enough to have as a second option in a travel situation and I’m happy to use it.

Powerful and great for travel

A powerful 40W dual charger that was designed perfectly for my travel needs. The unit is small, and the plug collapses for easy packing. The power charges my Apple Watch Series 8 very quickly. I can charge the watch only once a day, usually while I am getting dressed, and it is ready to go for the whole day when I am. I highly recommend this charger, and I have ordered three more to give as gifts.

Dual charging for tablets.

We use wall adapters to charge the kids' electronics on trips. With the iPad mini 4, we were able to charge both devices at the same time with a dual USB-A adapter. Since upgrading to the iPad mini 6, we were only able to charge 1 device at a time. This adapter uses fast charging via USB-C and a high wattage so it is more than capable of charging multiple tablets at the same time. The adapter does not overheat like other poor-quality wall adapters. The plug folds in allowing for easy storage and travel without damaging the adapter itself.

3-2-1 and charged

This little block is fast at charging. Feels well made. But most importantly, the shape makes It the perfect block for behind night stand. Since It is slim and cables come from sides. It also stays in the wall outlet, unlike my previous model that kept falling off with slightest pull. Been using for a month now to charge apple watch and iphone, so far zero issues.

Works with Super Fast charging mode on Samsung Galaxy S22 Ultra

This charger met my needs completely. I needed a charger that was flat enough to not stick out far and be able to be used in a very compact space inside of my nightstand. This charger is super flat, and actually give me two charging ports. The two charging ports are Type-C outputs so that means that a type c to type c cable has to be used when trying to use this on most of the newer Samsung phones, such as my Galaxy Note 22 Ultra. The charger works wonderfully on my Galaxy Note 22 Ultra, and actually charges it in super fast charging mode! I love how fast it charges and not having to wait very long for my phone to be ready. I can put it on the charger for just a few minutes, and have a large amount of battery for the rest of the day.

versatile charge block

This makes a nice night stand charging block. It has two ports so you can charge a phone and a second device (watch, tablet, etc.) simultaneously. It can also deliver 40w of power to a single device like a laptop that might be occasionally used. It is compact. Easy to recommend.

Small and mighty

Cute solid little charging block. Has a nice weight to it, enough that feels like a quality product. Two USB C ports make it convenient. Over all, very happy with this block - far better priced than similar product direct from cellular manufacturer.

I now am a proud owner of two Uptab chargers

This charger feels excellent and rivals the quality of another brand that rhymes with anchor. It performs perfectly and it's now my go to EDC charger in combo with my 140w Uptab charger.
