Greater than one weekThis is a small, compact charging block that I have been using for my iPhone. I keep it in my work bookbag. Its easy to travel with it because its small, but the prongs dont fold in. That would be the only drawback, but no big deal.

Greater than one weekI dont usually leave reviews but since the new phones dont come with chargers anymore, I did so much research to find the best charger for the best price. First of all, I didnt even know about GaN until I was researching for a new charger for my pixel 7. My new charger had to be GaN, after reading up on it. If you are buying a new charger thats not GaN you are making a huge mistake. Even though the pixel 7 can only support charging up to 20w, I wanted to get a charger that will be somewhat future proof. This supports up to 30w. Since new phones dont come with chargers this will be used for my next several phones. The design of this charger is what I wanted. I bought the white because the pixel cable that was included with the phone is white. Its matte white too, not that shiny white plastic which get scratched which looks terrible over time. The other options I seriously considered were UGREEN and ANKER. Both of them were exactly twice the price of this VOLTME. I assumed the VOLTME is cheaper because not make people are buying it. I have never heard of VOLTME before researching chargers but after seeing YouTube reviews and looking at their website they are not a cheap knock off brand. Its a legit brand. The specs of all 3 brands are 100% equal. Even if all 3 brands were priced the same I would select VOLTME over the other two based on the design. The other two had shiny plastic which I know will scratch and look terrible. Hope this saves you time since Ive done the research.

> 3 dayI took a chance on this random brand because it was on sale and because it was ostensibly a 30W GaN charger. First impressions are good. It didnt self-immolate when plugged in; it charged an iPad Pro quickly and without any drama. The charger became warm but not too hot to touch. Some of the other VOLTME charger bricks have foldable prongs but this one has fixed prongs. From a size perspective, it is ever so slightly larger (length/width) than an Anker 511 Nano 3 30W charger. However, the depth of the charger (from tip of prongs to USB-C port) is shorter than the Nano 3. If it holds up it will be well-worth the price I paid (which was ~ 50% off list.) I also included a snapshot of the backside of the charger, where all the print is. Interestingly, the QR code generates a bunch of text including the model # and stuff -- googling it resulted in no results, which I found suspect. UPDATE: I charged a laptop that contains a 6000 mAh battery and the charger was hot to touch. However, this was no different from the Anker GaN Nano referenced above - they were both equally hot to touch. Not burning hot, but certainly more than just warm. I do not think this will be problematic because I think this is how these chargers behave.

05-06-2025Hi everyone! Sean here with another review for you. Todays item is the VOLTME Revo 30W GaN power brick. First off, you might be wondering what GaN means. It is the chemical abbreviation for Gallium Nitride, which is used in the composition of the semiconductors in high-quality chargers. It is used because it improves the conduction of electricity, meaning that they can charger faster and more efficiently than other chargers. Back to the VOLTME. For my test, I connected the power brick to a magsafe wireless charger, which was then hooked up to an iPhone 12 Pro Max. Here is the low-down of my observations: [THE GOOD] - SIZE: It is smaller than many other GaN chargers for its class - PERFORMANCE: Works as intended, and at a rate that is noticeably faster than with a non-GaN power brick - SAFETY: This product, even at a sustained charge for 30 minutes, did not feel warm or hot to the touch - AESTHETICS: It looks reminiscent of an Apple iPhone charging brick, but slightly larger and with stylized imprints on the sides that also act as grips when pulling or inserting the brick to an electrical socket. [THE BAD] - PRICING: GaN power bricks are generally more expensive, and this product follows that trend. Its price point is comparable to competitors in the space, however. [THE UGLY] - STRENGTH: This is only a 30W GaN. There are 60W GaNs that are only slightly more expensive, making it a more sensible choice if you have devices that can take in the higher output. And if price isnt an issue, there are GaN power bricks that are at 150W (and potentially greater). Bottom line: This is a great power brick, with a compact and solid design. It works well for what it is, and is priced at a competitive level. This is definitely a must-have for the professional on the go, because it can fit into any bag and then be used to quickly recharge a device in a pinch.

> 3 dayThis Voltme brick will charge your iPhone 14Pro/ProMax and most android phones at full speed. It provides more power than my Pixel 7 pro, with a max charge speed of 23w, could munch. I rarely come across any new USB-C charger brands that seem to be fairly higher quality, Voltme feels like it is. Feels very solid in the hand, and has a distinctive graphical logo on the side. Gripes: Takes up more than one plug size on a power strip, see my pic, you will have to give it a larger plug at the end etc. Would be better If it had a foldable plug. Overall quite good build quality, and fairly compact, but not the most compact 30w Charger out there.

> 3 dayIt’s silent. No high frequency noise, even when charging, unlike most devices of its size and type.

> 3 dayI was highly skeptical after buying multiple fast chargers on Amazon that failed to deliver more than 10W. But this charger is actually fast, small and doesnt get hot (only slightly warm). See the photo for power consumption when charging an iPhone 12 Pro Max.

> 3 dayVolume 33w charger This little charger is significantly smaller than even Apple’s own OEM 20w charger. In fact, it’s more powerful and yet much smaller. ALL OF THE PROTOCOLS are supported that is listed on this charger. (See test images) Comes in assorted colors too and for the price, it’s much better deal than the OEM apple 20w charger. Rest assured you are getting a genuine 33watt charger. Not a fake one like so many listed on Amazon. For the price and performance after testing, this is a solid 5-star charger. The only thing I’d like to see it support is a foldable outlet prong. Otherwise, it’s still amazing they can fit so much power in a small little package like this. After conducting some charging tests on many devices (iPads, iPhones, etc), the GaN charger does not get HOT at all. Luke warm to warm at touch but nothing to note. A well made product!
