consider safety for your health and the people around you

General safety suggestions:

It is advisable to always have the following items nearby and in a good condition

  • Eye protection clean and scratch free
  • Hearing protection quality earmuffs
  • Dust masks discard old and dirty masks
  • Gloves for easy handling of material and hand protection
Wear Gloves
Eye Protection
Hearing Protection
Dust Mask

To use router bits safely (and to get the best results from your router), the router bits need to be installed properly into the router's collet. Improper installation of your bits can cause excessive chatter and could increase the likelihood that the bits will break when in use. 

Clean and sharp

First of all, before beginning any routing operation, check your bits to make sure that they are clean, relatively free of pitch, and most of all, sharp. If the bit is dull, chipped, is excessively burned or has any other defect, it should be sharpened or replaced before use. 

Correct collet and collet nut fit

Most router collets have a recess (groove) that needs to click into a circlip that resides inside the collet nut. Failing to ensure that the collet 'clicked' into the collet nut will cause you to struggle to remove the router bit after tightening. This could cause the collet to break or be removed by a technical repair centre.

 

Correct fit inside the collet

When installing the bit into the collet, do not tighten the collet with the bit 'seated.' Instead, insert the bit until the shank (bit shaft) reaches the bottom of the collet, then ease it out about 2 mm before tightening the collet.

When the bit is tightened, there should be no less than  2/3 's of the length of the shank in the collet. If your bit has a shank that is too short, then the bit should be replaced. 

 

Safety gear

There are a few other safety measures to keep in mind whenever you use your router. First of all, remember to always wear appropriate safety gear as indicated above.

Correct speed setting

Second, be sure to set your router to the proper speed for your router bit. Setting your router to an incorrect speed will not only affect the router's performance, but also can cause the bit to break much more easily and even cause bodily harm. The speed at which a router bit turns can be important. The typical router runs at about 22,000 rpm, which is fine for most bits. But as the diameter of the bit increases, you ll want to slow things down.

Also, before beginning any routing operation, be certain that you give the router's motor time to come up to full speed for the chosen setting. Beginning to cut before the bit is at full speed can give less than desired results. 

Observe the following at all times

  • Wear a protective face shield or Safety Glasses to prevent eye and face injury.
  • Wear ear plugs or ear muffs to protect your hearing.
  • Use a respirator or dust mask to give protection from dust particles. Wood dust may remain in the air for hours after using power tools.
  • Always read and follow router operator's manual instructions.
  • Make sure that router rpm's and the bit selected match.
  • Dress properly. Wear short sleeves, no loose fitting clothes, proper footwear and no jewellery. Tie back long hair.
  • Always be sure the router is unplugged before replacing bits and that the switch is off before connecting the router.
  • Be sure the router bit has completing stopped spinning before sitting the router down.
  • Be sure bits, clamps and attachments are secure before starting up.
  • Keep children, pets and visitors at a safe distance.
  • Be especially cautious when working small pieces.
  • Keep hands and fingers away from revolving bits and cutters.
  • Do not operate routers in moist or wet areas.
  • Always grip tool tightly and be prepared at start-up to resist the motor torque.
  • When using a router table, make sure on/off switch is easily accessible.
  • Learn the sound of your router and shut it off at any unfamiliar sounds or irregularities.
    Never start the router with the bit in contact with the material.
  • Always feed in the proper direction, against the direction of bit rotation.
  • Maintain equipment. Replace worn parts, discard worn-out bits and check router periodically. Clean parts with appropriate solvents.
  • Don't operate a tool if you are tired or under the influence of medication, drugs, alcohol or while smoking.
  • Check wood for nails, screws or loose knots before routing.
  • Keep your mind on your work, avoid distractions, work at a comfortable pace and stop before you get tired.

Do a dry run

  • Place the router on the final work surface and test you cut by moving the router over the whole are to cut with THE ROUTER SWITCHED OFF
  • You do not want to waste an expensive piece of wood
  • You do not want to start all over
  • Never met anyone with spare fingers - SAFETY

Using a Router in a Router Table

Router Table Safety

Although most router bits are small, they can be potentially dangerous and should deserve your attention and respect.

1 Use push sticks or a push block to position your hands a safe distance from the router bit.

2 Use large-diameter bits only in a router table. Using bits over 25mm Ø (diameter) in a handheld router can possibly cause you to lose control of the tool and harm yourself or bystanders.

3 Always wear a dust mask as well as eye and hearing protection.

4 Take light cuts. Heavy cuts invite kickback. If necessary, move the fence closer to the bit or switch to a larger guide bearing/bush.

5 Use a featherboard (anti-kickback device) to support the workpiece against the router table and/or fence.

6 Never climb-cut. Always feed the stock from right to left. Against the rotation of the router bit. (see illustration)

7 Avoid routing small stock. Instead, rout a larger piece and cut it to size afterwards. If you absolutely have to profile a small piece, build an suitable jig or secure the workpiece.

8 Always use a guard. If the fence didn t come with a guard, make your own.

9 Never start the router with the bit in contact with the material.

10 Don t force the router bit or overload the router. Excessive heat is an enemy.

11 Secure/fasten the router in the base before starting/switch on the router.

12 Don t bottom out the bit in the collet or partially insert the bit. Instead, completely insert the bit, and then back off approximately 2 mm. At least 2/3 's of the router bit shank should be inside the collet.

13 Be sober and not under the influence of medicine that causes a lack of concentration

14 Tidy up your workshop to ensure the ability to move freely with enough room around the router table

Good, but a little spendy and lower capacity for value
Color: Black
I have used this plenty at work anytime I forget to charge my Samsung S25 Ultra (which has a 5,000mah battery) or am using it intensely, often for work. The charge time is actually the new Qi 2, so it's not bad. It's not a fast charger, but it's super good enough to not bring a cable. It's slim enough to not care as well. I am a nerd and keep it in my cargo pocket which also helped save the day for some poor lady who needed to charge her iPhone, so I lent that to her for a short bit. It's super unubtrusive to keep on you so it's handy if or when you need it, or need to help. I like Anker as a brand, and lean to them for battery banks. I have several of their batteries, so I figured I will eat the premium to get the portability. I like the form a lot, and the magnetc retention is rock solid. Charge speed is fair, and heat isn't what I would call concerning if this isn't something you do with frquency. A 5,000mah battery will not go far in real world use. One full recharge, which is perfectly suitable. The price is what will hurt. You can get a conventional bank for the same with much more capacity. It won't be as slim and likely won't be wireless (or as fast). I rather like this battery but am hesitant to recommend it. It really is a case of do you want slim and portable or capacity and budget? It is a solid product, however you decide.

Best travel MagSafe Charger
Color: Black
I recently purchased the Anker Nano MagSafe Portable Charger, Ultra-Slim 5,000mAh, and it has quickly become one of my favorite everyday tech accessories. The compact design and reliable charging performance make it incredibly convenient for keeping my iPhone powered throughout the day, whether I’m commuting, traveling, or simply away from an outlet for extended periods. One of the first things I noticed was how slim and lightweight the charger feels. It attaches securely to the back of the phone with MagSafe, making it easy to use while still comfortably fitting in a pocket or small bag. Unlike bulkier power banks, this one maintains a sleek profile that doesn’t add unnecessary weight or thickness. Charging performance has been very reliable overall. The 5,000mAh capacity provides a helpful boost when my battery starts running low, and the magnetic connection stays firmly in place during use. I also appreciate that the charger delivers consistent power without overheating, even during longer charging sessions. The build quality is excellent, which is something I’ve come to expect from Anker products. The materials feel durable and premium, and the minimalist design looks clean and modern. It arrived well-packaged and immediately gave the impression of being a high-quality accessory. Another feature I appreciate is how simple and convenient it is to use. There’s no complicated setup involved—just snap it onto the back of the phone and charging begins automatically. It’s especially useful when traveling or during busy days when carrying cables around can be inconvenient. After using it regularly, I’ve been very satisfied with its reliability and portability. It keeps my phone charged when I need extra power most, and the ultra-slim design makes it easy to carry everywhere without noticing the extra bulk. Overall, the Anker Nano MagSafe Portable Charger, Ultra-Slim 5,000mAh is a dependable and thoughtfully designed portable charger. It offers reliable charging performance, excellent portability, and premium build quality. I would definitely recommend it to anyone looking for a compact and convenient MagSafe-compatible power bank for everyday use.

A really great portable charger
Color: Golden
Works great with my Samsung Galaxy S25 in a magnetic case. I love the small form factor, which means I can keep it on my phone to charge while I'm using the phone when I need to. It also means it's incredibly easy to take any time I leave the house, not just when I travel. It does get pretty warm, but I find that keeping the phone face down helps that a lot. And of course using the phone while it's charging makes it hotter. One note if You're like me and you've never used one of these: there's a small button on the side that activates or deactivates the magnet. I thought the magnet had died because it was no longer attaching to my phone. Then I randomly held the button down and it snapped right back on. It's a useful feature now that I know that it's there, so I don't leave the magnet on when it might be near swipeable cards in my bag. Funny they don't mention anything about that in all the product images, but now I know.

Heat and Charging Complaints Are Unjustified
Color: White
Good product overall. I was going to give it 4 stars because it hangs slightly off the bottom of my iPhone 15 Pro but I realized it says 16/17. Those models might have the MagSafe ring slightly higher on the phone in which case it would fit cleaner. I was worried about Heat after reading the reviews. All inductive charging systems generate waste heat and all charging generates waste heat. It’s nothing extreme here. If it’s in your pocket without air flow around it, it gets quite warm on the phone for sure. In my hand, using the phone for a while plane flight, there’s enough flow that it’s just a bit warm. Battery life is as advertised. It’s somewhere around a charge or so, I didn’t check this scientifically. Plenty to keep you topped up through a cross country air trip. It’s very small and much nicer to have on the phone than some other models I’ve borrowed. Reviews have some complaints that it “doesn’t charge the phone”. That’s a goofy complaint. If the phone is dormant it will add charge percentage. If you’re streaming and emailing, on Bluetooth, and WiFi all at once you’re going to use power about as fast as it can supply without it spiking temperature. I was very happy to just sit at 75% my whole flight while constantly using my phone. It doesn’t matter if it added percentage, you don’t get this to charge your phone, you get this to extend the battery and it does just that. If you can leave your phone out of your pocket where it can breath/cool a bit you’ll be happy with this. Good product and some seem to be expecting it to cheat physics.

Quality 100W capable all-in-one USB-C hub from Anker
Style: 7-in-2 4K@30Hz, Style: 7-in-2 4K@30Hz
I recently added a 16" MacBook Pro to the family and with the extra size/weight wanted to slim down on carrying adapters. I also have a 13" MacBook Pro (2018) and wanted something that would work for both of these without any shortfalls. The Anker delivers and works flawlessly on both of my MacBooks. Charging - It offers full rate charging on either unit and so far - hasn't gotten all that warm in the process. I expected a bake fest and me returning it, so was surprised there. Plugs/Ports - I skipped the Hyper-hub craze as I just never liked the fit into my MacBooks. So this is the first dual-port type device I have used on my Mac's, but it fits very well and doesn't feel like anything needs to be forced to work. Likewise on the receiving side, the card slots are friendly and you won't lose your cards, but it still holds them well. The USB-C ports respond well and have worked with all charger cables and dongles that I have. The USB-A's are classic Anker quality. Thinking about this more...I think I actually like plugging and unplugging things in this. There are some brands (cough: UNI) that I wonder if "this is the time" when it breaks on me or keeps my cable end. So far so good on the Anker. Peripherals and what works - I have only used portables on it a few times so I do not have much testing with NVME there yet, but SSD is just fine and works as normal. Only (1) port of this has Displayport active on it (the charge port). So if you are plugging in two screens to one side of the MacBook - that will need to change. At the same time, if you can convert one of those to HDMI you can connect the HDMI and then Displayport (via USB-C) over the charge port. In addition to fitting the ports well I should also mention - on the 13" MacBook Pro and Air this should lie mostly flush with the work surface you are on and the laptop edge. On the 16" MacBook Pro it does have a little gap under it due to the height of that unit. But it still does not protrude past the top edge and won't bug you if you brush your hand over it. TL;DR: At the time of this review I am about a week in. and have removed all the "docks" from my office and home so I can give this a decent test. At 60$ it is more expensive than other options, but performs very well for my needs. Cons: price I guess. I wouldn't mind a GigE Ethernet port on it at the same price point of 60$, or wait for it on sale if you don't care about the port. Big ANKER on the top of It sort of annoying, if I am picking nits. Pros: Quality interface, known brand, works well on multiple years of MacBook with no weirdness or driver problems. Compatible with latest models and software. Color matches the Apple Space Gray acceptably. I hope you found this review helpful, if not - leave a comment and let me know how we can change that! Thanks for reading my review, Chris
