Power Bank Under 1000: Why 10,000 mAh Gives 1.3 Charges, 8 Picks (2026)

Last updated: 28 October 2026

The best power bank under 1000 rupees (about $11) for most people is the Portronics Luxcell B 10K at about $7: 10,000 mAh, 22.5W output, a Type-C port that charges both ways and a one-year warranty. If you need two full phone charges, spend about $10 on the Amazon Basics 20000 mAh instead.

Below you'll find eight power banks under ₹1,000 (about $11) that are actually in stock on Amazon India this Diwali season, with the price we saw on 19 October 2026 converted to US dollars at ₹95 per dollar, the weight, the ports and the warranty. We also explain how much charge a 10,000 mAh pack really gives your phone (less than the box suggests) and the DGCA rules for carrying one on a flight.

Quick answer: The best power bank under 1000 in India right now is the Portronics Luxcell B 10K (about $7, 22.5W, 1-year warranty). Pick the Amazon Basics 20000 mAh (about $10) for more backup, the boAt Energyshroom PB300 Neo (about $9) for three devices at once, or the Philips 10000 mAh (about $11) if you want a percentage display.

Best power bank under 1000: comparison table

Prices are Amazon.in selling prices seen on 19 October 2026, during the festive sales, converted at ₹95 per dollar. They move daily, sometimes by $1 to $2 between colours of the same model, so treat them as a guide and check the live price before you pay.

What is the cost in Indian rupees? Amazon.in selling prices on 19 October 2026 (GST included): Luxcell B 10K ₹699, Amazon Basics 20000 mAh ₹949, boAt PB300 Neo ₹899 to ₹1,099, Philips 10000 mAh ₹999, Luxcell Mini 10K Advanced ₹999, Zebronics MB10000S15 ₹649, URBN Edge ₹899 to ₹967 and Luxcell B12 ₹539.

All eight use lithium polymer cells according to their listings. Weights are what the seller lists on Amazon; brand claims and listings sometimes differ, and we show both where they do.

A 10,000 mAh pack covers about one full phone charge, enough for a long day at college.

How we picked these power banks

Every pick had to pass four filters:

1. Selling under ₹1,000 (about $11) on Amazon.in on 19 October 2026. Two picks swing around that cap by colour, and we say so.
2. From a brand with an Indian address and a written warranty. Every listing here names an Indian manufacturer or importer and a warranty period.
3. At least 10,000 mAh. Anything smaller rarely gives a modern 5,000 to 6,000 mAh phone even one full charge.
4. Enough buyer feedback to spot problems. We preferred models with hundreds or thousands of ratings and flag the one that has very few.

Specs come from the brand's Amazon listing and, where available, the brand's own store. We have not run lab discharge tests on these units, so read the capacity section below before you compare "2 to 3 charges" claims.

The 8 best power banks under 1000 in India

1. Portronics Luxcell B 10K: best overall under ₹1,000

At about $7 the Luxcell B 10K is the easiest recommendation in this budget. It gives 22.5W from the USB-A port, a Type-C PD port that also refills the power bank, and a one-year manufacturer warranty from Portronics, a Delhi-based brand. It is the most-rated pick here, with close to 4,000 ratings on Amazon.

• Price seen: about $7 on Amazon (MRP about $19). The same model lists at about $11 on the Portronics store (opens in new tab), so Amazon is cheaper this week.
• Size and weight: 14 x 6.8 x 1.6 cm, 228 g.
• Ports: USB-A (22.5W), Type-C PD out and in, plus a wake-up button for low-power devices like earbuds.
• Skip it if: you want a percentage display. It uses simple LED dots.

2. Amazon Basics 20000 mAh 22.5W: most backup for the money

This is the only 20,000 mAh power bank with real buyer volume that sells under ₹1,000 (about $11) right now, at about $10 with about 2,900 ratings. Amazon's own listing says it can charge a 4,000 mAh device up to 3.5 times, which works out to roughly 70% of the printed capacity reaching the phone. That is honest, and it matches the physics we explain below.

• Price seen: about $10 (MRP about $42).
• Ports: two USB-A and one Type-C out; Type-C and Micro USB in. It charges three devices at once.
• Weight: 394 g. That's heavy for a pocket but fine in a college bag.
• Watch out for: only a 6-month warranty, handled by the service partner named on the listing.

If you take long train journeys or face power cuts at home, the extra 10,000 mAh for about $3 more than our top pick is good value. The Beetel Volte Series PB20 (20,000 mAh, 22.5W, about $9, 410 g, 6-month warranty) is a close alternative with fewer ratings.

3. boAt Energyshroom PB300 Neo: best for charging three devices

The PB300 Neo has three outputs (two USB-A and one Type-C) and two inputs, and it supports pass-through charging. That means you can plug the power bank into the wall and charge your phone from it at the same time, which helps when a hostel room has one free socket.

• Price seen: about $9 for the Electric Blue colour, about $12 for others (MRP about $26). boAt's own store listed Phantom Black at about $9 when we rechecked on 20 October.
• Charging standards: PD, PPS and QC 3.0 at up to 22.5W. PPS matters for Samsung phones (more on that below).
• Weight: 221 g, with a one-year warranty.

boAt's listing claims "2 to 3" phone charges. On a 5,000 mAh phone, expect closer to 1.3. Buy it for the ports, not that claim.

4. Philips 10000 mAh 22.5W: best with a percentage display

The Philips 10,000 mAh pack (model DLP1711NB/94, sold in India by Philiray Electronics) shows the exact battery percentage on a small digital display. That sounds minor until you're at a railway station guessing whether four LED dots mean 60% or 30%.

• Price seen: about $11 (MRP about $26) in Slate Black, Alba White and Deep Cyan.
• Ports: two USB-A and one Type-C output, Type-C and USB-A input.
• Weight and warranty: 233 g, 12-month warranty against manufacturing defects.
• Note: it has fewer ratings (about 140) than the Portronics or Amazon Basics models.

5. Portronics Luxcell Mini 10K Advanced: best pocket-size pick

The Luxcell Mini is the one to buy if the power bank has to live in a jeans pocket. Portronics says it weighs 175 g; the Amazon listing says 190 g. Either way it's lighter and shorter than a standard slab.

• Price seen: about $11 (MRP about $21).
• Ports: USB-A at 22.5W and Type-C PD at 20W, so an iPhone on Type-C gets its full 20W.
• Warranty: one year, BIS-approved according to the listing.
• Trade-off: it's thicker (2.1 cm) to make up for the smaller footprint.

6. Zebronics MB10000S15: cheapest 22.5W power bank

At about $7 this is the lowest price we found for a branded 22.5W pack with a PD 3.0 Type-C port and PPS support. It also has an LED percentage display, which is rare at this price.

• Price seen: about $7 (MRP about $22).
• Ports: dual USB output plus Type-C; Type-C and Micro USB input.
• Recharge time: 3.5 hours, per the listing.
• Watch out for: a 3.8-star average and a 6-month warranty. That's lower than the Portronics, so we rank it below.

7. URBN 10,000 mAh Edge: best for homes with iPhone and Android

URBN's Edge has two Type-C outputs and one USB-A, with PD and PPS at 22.5W. Its display shows battery percentage, plus output voltage and current, so you can see whether your phone is actually fast charging. URBN says it charges an iPhone 15 to 55% in 30 minutes.

• Price seen: about $9 to $10 depending on the listing (MRP about $21).
• Weight: 180 g listed, slim build.
• Warranty: 6 months.
• Caution: it's a new listing with only about 33 ratings. Buy it for the features, knowing long-term reliability data is thin.

8. Portronics Luxcell B12: cheapest branded option

The Luxcell B12 costs about $6 and is the right pick for a feature phone, earbuds, a smartwatch or an elderly parent's basic Android. It tops out at 12W from a single USB-A port, so a modern phone will charge slowly.

• Price seen: about $6 on Amazon (MRP about $16).
• Ports: one USB-A out, Type-C in. Cable included.
• Weight and warranty: 220 g, one year.

Worth stretching to? The Xiaomi Power Bank 4i (10,000 mAh, 22.5W, built-in Type-C cable, steel body) costs about $13. If you hate carrying cables and have about $2 more, it's a good buy, but it's outside this list's budget.

Which mAh power bank is best for you?

For most people, 10,000 mAh is the right size: it gives one full charge plus a top-up to a typical phone and weighs around 200 g. Choose 20,000 mAh only if you need two full charges away from a plug, and accept carrying about 400 g.

The number on the box is not what reaches your phone. A power bank's cells store charge at 3.7V, but USB delivers it at 5V or more, and the conversion plus heat loses energy. In practice about 60 to 70% of the printed mAh ends up in your phone's battery. Amazon Basics' own "3.5 charges of a 4,000 mAh device" claim from a 20,000 mAh pack shows exactly this.

Many 2026 budget phones now ship with 6,000 mAh or bigger batteries. If yours is one of them, a 10,000 mAh pack gives one full charge and not much more. Check your phone's battery size in Settings > About phone before choosing.

Voltage conversion and heat mean only about 70% of the printed mAh actually reaches your phone.

How to choose a power bank: 6 checks before you pay

Here is how to choose a power bank in two minutes, in the order that matters.

1. Match the protocol, not only the watts. iPhones fast charge over USB-C Power Delivery (PD). Samsung's "Super Fast Charging" needs PPS. Most Xiaomi, Redmi, realme and Vivo phones accept Quick Charge or PD at lower speeds. A 22.5W pack with PD and PPS covers almost every phone.
2. Expect 22.5W, not your charger's 45W or 67W. Phones with proprietary 33W to 120W charging fall back to around 18W to 22.5W on any third-party power bank. That's normal, not a fault.
3. Look for a Type-C input. Micro USB input refills slowly. Listings for these packs quote 3 to 3.5 hours to refill with a fast charger; an old 5W charger can take all night.
4. Check the BIS R-number. Power banks sold in India fall under the BIS Compulsory Registration Scheme. The R-number is printed on the body. You can verify it in the BIS Care app or on the Bureau of Indian Standards website (opens in new tab). Skip any pack without one.
5. Read the warranty line. Portronics, boAt, Philips and Xiaomi give one year here; Zebronics, URBN, Amazon Basics and Beetel give six months.
6. Compare the weight with your pocket. 10,000 mAh packs range from 170 g to 230 g in this list. A 20,000 mAh pack nearly doubles that.

Cheap packs also get hot. Some warmth during fast charging is normal. A pack that is too hot to hold, smells, or bulges should go straight to e-waste. Our guide on phone heating problems and fixes explains why charging your phone from a hot power bank under a pillow is a bad idea.

Is a power bank allowed in flight in India?

Yes, but only in cabin baggage, and you can't use it on board. Since the DGCA's January 2026 clarification, Indian flights ban using a power bank to charge any device during the flight, including through seat power outlets, according to IANS reporting (opens in new tab) of the rule.

Here's what that means for a 10,000 or 20,000 mAh pack:

• Hand baggage only. Power banks are not allowed in checked-in bags. Airport security will pull them out.
• Not in the overhead bin. Keep it in the bag under the seat in front of you, as Akasa Air's power bank guide (opens in new tab) explains.
• Under 100 Wh is fine. Multiply mAh by 3.7 and divide by 1,000. A 10,000 mAh pack is 37 Wh; a 20,000 mAh pack is 74 Wh. Both are well under the 100 Wh limit, so every pick in this list is allowed.
• Keep it switched off. Treat it as an inactive item for the whole flight.

Rules can change after incidents, and airlines can add their own limits, so check your airline's baggage page a day before you fly.

Power banks must travel in your cabin bag, never inside the checked suitcase.

Which power bank should you buy?

Pick by how you use your phone:

• College student with a full day outside: Portronics Luxcell B 10K (about $7). Light enough for a bag, enough for one full charge. Pair it with budget earbuds under ₹2,000 and the wake-up button keeps them topped up too.
• Long train trips or power cuts at home: Amazon Basics 20000 mAh (about $10).
• One socket, many gadgets: boAt Energyshroom PB300 Neo (about $9 to $12), thanks to pass-through charging and three outputs.
• You want to see the exact charge left: Philips 10000 mAh (about $11) or Zebronics MB10000S15 (about $7).
• Pocket carry: Portronics Luxcell Mini 10K Advanced (about $11).
• Earbuds, smartwatch or a parent's basic phone: Portronics Luxcell B12 (about $6). It also suits the trackers in our best smartwatch under ₹2,000 list.

What is the cost in Indian rupees? On Amazon.in on 19 October 2026: Luxcell B 10K ₹699, Amazon Basics 20000 mAh ₹949, boAt PB300 Neo ₹899 to ₹1,099, Philips ₹999, Zebronics ₹649, Luxcell Mini 10K Advanced ₹999 and Luxcell B12 ₹539.

A Diwali tip: the sale price on Amazon is often lower than the brand's own store this month (about $7 against $11 for the Luxcell B 10K). Still, buy only from the brand's official storefront on Amazon, or from the brand site, so the warranty is valid. The same habit that helps you check if a phone is original or refurbished applies here: check the seller name before you pay.

Power bank under 1000: six facts to carry to checkout

• Default pick: Portronics Luxcell B 10K at about $7, with 22.5W, Type-C in and out and a one-year warranty.
• Need two full charges? The Amazon Basics 20000 mAh at about $10 is the only well-rated 20,000 mAh pack under ₹1,000 (about $11) this October.
• Divide the box number by roughly 1.5: a 10,000 mAh pack puts about 6,500 mAh into your phone, or 1.3 charges of a 5,000 mAh battery.
• PD for iPhones, PPS for Samsung. 22.5W is the ceiling at this price.
• Find the BIS R-number on the body and read the warranty line (one year beats six months).
• Flying? Cabin bag only, switched off, never used on board.

Buy the Luxcell B 10K unless you need two charges

One long day away from a plug is what most people need from a power bank under 1000, and the Portronics Luxcell B 10K at about $7 covers it. If you need two full charges, the Amazon Basics 20000 mAh at about $10 is the better buy. Either way, check the BIS R-number, prefer a one-year warranty, and keep the pack in your cabin bag when you fly.
