Buyers who expect it to charge laptops will be disappointed due to the 33W limit, but regular smartphone users will find great value here.

Should you buy this?

Buy it if: If you are a frequent traveler needing reliable backup power, at ₹1,999 this massive 20000mAh battery makes complete sense. It easily handles multiple phone charges during long days out. You do get convenient triple output ports for sharing power, though you must live with the heavier weight and larger size in your travel bag. If you are a college student juggling a smartphone, tablet, and earbuds all day, this power bank fits your routine well. At ₹1,999, the 33W fast charging keeps your gear topped up between classes without hassle. Just keep in mind that its maximum output won't be enough to charge a standard laptop efficiently.
Skip it if: If you are a remote worker or professional who needs a portable charger to power up your laptop, you should skip this model. The 33W output is capped too low for laptops, and you would be much better off looking for a 65W or higher power bank instead. If you prefer a lightweight charger that easily slips into a tight pocket or small purse, avoid this item. The 20000mAh capacity cell makes the unit bulky and heavy, so you should look for a slim 10000mAh power bank instead.

How this rating was made

The score comes from one evaluation of the Amazon specification table against today's cash price, calibrated so most consumer electronics land between 65 and 88. Affiliate partnerships never change a score, and no brand pays for placement. Where the store withholds a specification, the model is told to treat it as unknown rather than assume a good value.
