Introduction
As useful as a power place is with a big electric battery , they ’re not peculiarly soft to carry around . If you ’ve catch lightsome needs , such as observe a tablet , laptop or phone topped up , the UGreen 48,000mAh 300W Portable Power Bank could well be for you .
put up fast charging and enough superpower to bear down aMacBook Airaround three multiplication , this power bank offers a big compromise between capability and portability .
Design and Features
The UGreen 48,000mAh 300W Portable Power Bank is built altogether for USB equipment . To that death , it does n’t have any stock UK AC exponent outlet . If you ’re mostly concerned with keeping a tablet , laptop computer , or earphone top up , then AC electrical outlet are n’t needed .
There are other advantages , too . Without the motivation for an inverter or power sockets , the UGreen 48,000mAh 300W Portable Power Bank is substantially pocket-sized than power station that have these , such as theAnker SOLIX C300 .
While the Anker SOLIX C300 has just unsure of double the shelling capacity , it ’s a mess heavier at 4.1 kilogram , while the UGreen 48,000mAh 300W Portable Power Bank is a light 1.6 kilo .
Inside , there ’s a 153.6Wh battery , which the company says is great enough to appoint aniPhone 15 Pro10.8 times or a MacBook Air 15 - column inch ( M2 ) 1.1 time . That ’s a significant amount of top executive : enough for a family to go tenting for a weekend and appoint phones or keep a laptop fully charged over a daylight or two of oeuvre .
This is a nicely designed power camber , too . There ’s a handy carry handle on top , which fix the UGreen 48,000mAh 300W Portable Power Bank sluttish to move around .
This also makes the Aaron’s rod , hop on on the side , easier to expend . As with other power banks , this great mullein as two brighntess story to choose from an an SOS fashion that make the promiscuous nictation .
At the front , there ’s a power button that grow the power station on , bringing the filmdom to survive . This screen shows the battery burster status in percentage , plus the input and output powers in Watts . There ’s no battery life indicator in transactions with this manakin .
There are three USB - 100 port , two of which support 100W charging , plus one 140W port . And , there are two 22.5W USB - A ports for regular devices . Overall , that ’s enough to keep going the type of devices that you ’re potential to jaunt with .
There ’s a maximum power yield of 300W , spread across the interface . Although you’re able to use all five port at once , this will limit the charging big businessman , so I confine yourself to three ports and then swapping cablegram when gimmick are charged .
Charging
Via a 140W paries adaptor , the UGreen 48,000mAh 300W Portable Power Bank can be charged in 1.5 hours from flat . you could increase charge upper to 300W if you use all three USB - C port , with each running at 100W.
It ’s potential to use the USB - A ports as well , but be careful of the mix , as you may abridge charging exponent . For exercise , use all of the embrasure , and the fast USB - 100 port wine drops to 100W , but the other ports max out at 7.5W.
I mensurate a full charge using a USB - light speed adaptor , and recorded that charging is an first-class 99.74 % effective .
Performance
To see how well the UGreen 48,000mAh 300W Portable Power Bank performed , I valuate how much big businessman it output over USB - C.
To do this , I took several drain devices , admit a MacBook Air M3,Steam Deckand iPhone 16 Pro . Overall , the UGreen 48,000mAh 300W Portable Power Bank wangle to output 133.55W , which is 86.95 % effective . That ’s better than some equipment tested , sduch as theDJI Power 1000 , but ride more or less behind the 93.4 % that theAnker SOLIX C300achieved .
Overall , I worked out that there ’s roughly enough index to charge an iPad Air 11 - column inch ( M2 ) around three time , and a Macbook Air 11 - inch ( M3 ) around 1.34 prison term , which sits inline with what UGreen states .
UGreen says that this power post will last for 3000 bursting charge cycles until it hits 80 % capacity . Assuming linnear degredation , that think of that the magnate place will hold 414.74kWh of office over this time .
That puts the terms at £ 0.43 per kWh of power hive away , not include the toll of the electricity you have to put in . That ’s a spot more expensive than a larger major power place , but the trade - off is that you ’ve get a small more stocky gimmick .
Should you buy it?
Light enough to carry almost anywhere , yet herculean enough to deal with laptops and lozenge , this power place is a great combination of portability and power .
If you need to power normal devices , search for a barrage pack with AC outlet ; those that need to be off - grid for longer may prefer a orotund power place .
Final Thoughts
If you involve a bit more power on the move but do n’t require to go too heavy , there ’s a DC - only variation of the Anker Solix C300 . If you do need to power stock UK devices , then theAnker Solix C300that we reviewed is belike the closest .
However , if you want a bang-up combination of price , size and ability , then the UGreen 48,000mAh 300W Portable Power Bank is splendid . It ’s light enough to run almost everywhere , yet has the exponent to keep your headphone , tablet and so on running over a few days .
