Best Power Bank (Portable Charger) Under $30? Let’s find out!

Samsung devices fast charge using their special PPS protocol. Samsung is a poor way to test for USB PD fast charging speed.

Omg another awesome video thank you so much for all your hard work. Do you have the milwaukee m18 175w inverter? If so can you see what the output power is on the USB a and c? When I use the USB c port to charge my phone it comes up superfast charging on the phones screen. I never seen that before and would live to see how fast it's really charging. Thanks so much

Yes I would like to see more on solar recovery power banks...good content and thanks

99% of these are Chinese garbage and will fail bf 12 months. Misleading capacities are rampant in this sector

Just something to keep in mind with the capacity, basically every battery bank quotes the mAh rated capacity of its internal battery cell (because it's the biggest number) but none of them will get that when charging. That capacity is usually specced at something like 0.5-1A discharge rate (at the cell) and most phones will easily pull 2-3A or more from the cell, which reduces the output, plus the efficiency of the charge circuit (which should be in the 90s) so based on the 10W discharge rate, I would expect the ones within ~80% of their rating to be accurate. Plenty of them are just outright lying, 50% of its rating is unacceptable, but just keep in mind that none of these are going to actually match their stated capacity unless you rip the cell out and test that directly. It's a bit stupid, but at least it's pretty consistent that every company reports it in that way.

The main reason i don't trust any powerbank, is that probably all of them stopped working after only 3 chargers and then they died.
Powerbanks is the most unreliable electronics i have ever experienced. Even the famous Anker have failed for many early on.

excellent job Todd! Great review

Yeah. Can you do a video comparing other high quality power banks like the Anker 737? Like other anker products and Ugreen products and the like.

Can you do reviews on Endoscopes,

Love to see how well the solar paper banks work. I’m guessing 1 watt every hour

My favorite thing about your channel is just seeing these amazing physical experiments! Id love to see an episode on Carabiners and what sorts of tortures you can bring to them, thank you!

Please test out more high end power banks such as the Anker 737 designed to power notebooks, this video was very informative and a lot of people like myself stick to the end.

Off-topic I don't know where else to message you, I wish you would have a review about which is the best knee pads. I've been in the industry for 25 years and I wear a lot of different kinds of knee pads. But I would like to see you with your expertise sort out which one is the best, thank you I'll be looking forward to seeing the video

Hi, need to know the best glue work for bonding metal (aluminum) to Glass

roof, gutter, solar and battery for a house or ADU

A video on motorcycle Security chains would be great :) mine got stolen just recently:(

Best laundry detergent?

Cooler testing such as ones you'd take to work in the summer?

Center punch test?

I’m trying to imagine his collection of New Balance sneakers… it’s gotta be a whole entire wall. All organized by durability, functionality and color…

Of you're in the market for a power bank or charger I would also advice researching a bit in protocols like PD, PPS etc.

Figure out what protocols you require for your appliances and try to match it a bit. Also keep in mind cables need to support those protocols.

Luckily many devices are moving towards PD and/or PPS. But with PPS for example there is generally a limited range a supply can deliver. Not all manufacturers clearly advertise those.

The “brand” names…..

Could you test wireless charging pads and cigarette socket usb chargers?

I know you tested chemical drain openers including enzyme/microbiological products in the past. You found the enzyme products ineffective for (rapid) drain opening but mentioned they might be good fro drain maintenance. These products are also sold for maintenance of septic systems. It would be interesting to see a variety of these enzyme/micro products in a longer duration test to see if they have any benefits for septic systems.

Best laundry detergent? Can you test that?

I would love to see a comparison on steel dump carts > 12 cu ft. I just broke my 3rd dump cart in 8 years and would love to find one that can stand up to heavy loads. Ohio Steel 20 cu ft, John Deere 18, etc. throw in some poly darts for comparison. :).

What’s “VERY IMPRESSIVE” is this channel.

I would love to see your in depth and rigorous testing of cordless, rechargeable precision screwdrivers.
Some have built-in batteries, while a few offer replaceable, rechargeable batteries.
For me, torque (electric powered), lighting, speed, battery duration and locked torque for snugging up or loosening screws.

happy ur doing this..very informative content

Thanks you are awesome!

I would love to see reverse osmosis systems compared. They range in price but seem like they all do the same thing. Plus, is it any better than a Zero Water filter?

Best flat file or round file next?

Great video! I always enjoy watching your reviews. Here’s a couple of ideas for future reviews. Maybe a review of cheap digital battery chargers?Also, there’s a lot of Chinese cam chains, cam chain tensioners, clutch kits and top end rebuild kits for popular Japanese ATVs, Honda’s TRX300FW, Yamaha Warrior etc. Would be nice to see a comparison between stock Japanese OEM parts vs the cheap Chinese replacement parts.

The only thing I use a power bank for is to power LED strip lights.

It is missing ravpower.

Great video as always!

I have a suggestion for a new video for you. You should do a comparison of shoe glue types.

I noticed the sole on my right shoes is starting to separate from the boot part. The shoe is in great condition otherwise. I think it's from when I sometimes cheat taking the shoe off where yoh use other foot as leverage on the trim of the sole.

I usually search up for your channel first before getting things like shoe glue but you don't have a video on it yet. Hopefully you see this and decide to give it a try before I need to commit and make the repair.

I would like to see a lawn mower test.

I would recommend Anker PowerCore 26800 Portable Charger, 26800 mAh Battery, I have had it for 2 years and it has never left me down in airports where there is no place to charge my cell phone, I have charged it using my portable charger and also the people at the airport asked me to charge their cell phones and this charger charges them very quickly. This charger got me out of a lot of trouble I bought it on Amazon

At this point number and output of USBC ports is really what matters.

Nitecore stuff...review please..lol

Best axe?

Love to see a show down with the top handle battery chainsaw like M18 Milwaukie 2826-22t vs Dewalt and more
Love your video New 2023 and 2024 saws

I would love to see more of the expensive power banks like shargeek

Could you please test faraday bags.

I just found out that k and n makes a washable hvac filter...
Can you do another video on hvac filters?
I would love to see how a washable filter stacks up.

I try wiress adapters there over and onde change my phone.

Solar power bank review please

H yea!

This is definitely the guy we need. Single handily destroying cnet lol
