Baseus Blade Professional energy financial institution evaluation
Whereas a superb energy financial institution for a lot of causes, the Baseus Blade Professional actually stands out for its skinny type issue, mixed with a big 20,000mAh (74Wh) capability and beefy 100W (20V, 5A) output. There are only a few such energy banks that may slot right into a laptop computer sleeve, but nonetheless supply quick charging, making this my favourite possibility when touring mild.
I additionally suppose the Blade Professional is a superb possibility for cellphone charging if you have to do a number of top-ups, and the slim type works properly in a backpack too. That stated, at 13.4 x 13.4 x 2.0 cm (5.3 x 5.3 x 0.8 inches), it is positively too massive to slot in most pockets comfortably. The exception to that is cumbersome winter put on, and I’ve used it to energy a heated jacket in icy climate when touring.
The Blade Professional has two USB-C ports that may every output 100W, although if each are used on the similar time, they’re restricted to 65W and 35W respectively. The 2 USB-A ports can do 30W (12V, 2.5A) or 27W at 9V, 3A. Whereas charging three units is completely effective, plugging in 4 means all ports are restricted to only 5V output, which ends up in a lot slower charging, and will not cost most laptops.
Charging the Blade Professional by way of both USB-C port occurs at as much as 60W and takes about 1 hour and quarter-hour to achieve full capability. With a 65W or increased charger, the facility financial institution additionally helps pass-through charging, so you possibly can cost the facility financial institution and one other gadget on the similar time. This implies you possibly can plug the facility financial institution between your laptop computer and its USB-C charger, and cost each directly with no need to swap any cables as soon as it’s finished.
You additionally get a low-current cost mode for smaller equipment like headphones (which stops the facility financial institution from turning off when charging units that solely want just a little little bit of energy), together with a implausible show that exhibits the voltage, present and remaining runtime whereas charging.
At 440g (15.5 ounces) the Blade Professional is kind of light-weight for the dimensions, however the flat form means it is barely bigger in complete quantity than the smallest energy banks with comparable capability. For my part, that is greater than offset by the slim design, which makes it really feel a lot much less cumbersome.
I conduct complete testing of energy banks to verify they’ll meet the producer’s claims, as many do not truly do what they are saying they’ll. Total, the Blade Professional provides glorious outcomes that earn it a spot in our best power banks information.
The 20,000mAh (74Wh) capability is sufficient to deliver typical laptops again to a full cost (or not less than hit 70% for these with massive batteries), or cost a cellphone three to 4 instances over, relying on the mannequin.
In testing, when outputting the complete 100W for a sustained time frame, the Blade will decelerate the cost price to verify its cells keep wholesome long run. In our real-world testing with a high-power 100W laptop computer (which usually averages just below 100W), this safety function didn’t kick in.
That stated, with sustained excessive output, the Blade Professional does generate some waste warmth (which is completely regular), so you will get the very best efficiency if it is not left in a bag when charging a laptop computer. In case you’re simply charging a cellphone although, it stays very cool and could be tucked away.
The one different issues I can fault the Blade Professional for are that it tends to select up scratches simply, and after months of pulling it out and in of my bag, it has misplaced one of many little rubber toes.
If shopping for the Blade Professional, understand that it’s usually offered for as little as half the listing worth when on sale, and is usually less expensive than the costs listed under.
Additionally be careful for the older (non-Professional) Blade mannequin, as they give the impression of being very related. The older Blade is a superb energy financial institution (and purchase if discounted), and it has the identical options and outputs because the Professional, however bear in mind it’s bigger total and makes use of an older cell chemistry.
All in all, irrespective of which mannequin you go for, the Blade Professional is good for slipping right into a bag to cost a laptop computer and different units.

Baseus Blade Professional: Check outcomes
If all these numbers do not imply a lot to you, I’ve included scores out of 5 for every check end result so you possibly can see the way it fared at a look.
At phone-charging charges (20W / 9V / 2.22A), the Blade Professional delivers an impressive 91.55% of its rated capability. At 20V and typical laptop computer charging charges, efficiency is even higher, hitting 93% of the rated capability.
Throughout testing beneath a sustained 100W (20V, 5A) load, the Blade Professional will often renegotiate the output at 65W (20V, 3.25A) as soon as the remaining capability drops to someplace between 50% and 30%, primarily to handle warmth. At these increased sustained hundreds, effectivity takes a noticeable hit, and round 54.7Wh (76%) of the rated 74Wh finally ends up being usable.
This may seem to be a priority, however it is not an issue for regular use. However for those who do want an influence financial institution that may output the complete 100W for the whole capability, then think about a mannequin just like the Anker 737 or the ZMI No.20 – each of which might maintain their full output.

How I check energy banks
I get hands-on with each energy financial institution I can, and carry out in depth testing in each the lab and real-world eventualities. Utilizing tools just like the ChargerLab POWER-Z KM003C, I examine cost voltage, protocol assist, and log capability checks.
Every energy financial institution can also be examined with actual units, together with telephones, tablets, laptops, and extra, in addition to related to a programmable load tester for a number of cost cycles. I carry a range day by day in each pockets and baggage to evaluate their sturdiness and talent to resist tough, on a regular basis use.
